10 HP 10 Bar SJ VFD Variable Speed Screw Air Compressor – Model SJ RV10 The SJ RV10 is a 10 HP (7.5 kW) variable speed rotary screw air compressor designed for industrial applications requiring controlled compressed air delivery at a maximum operating pressure of 10 bar. With a specified airflow capacity of 34 CFM (0.96 m³/min) at 10 bar, the SJ RV10 combines rotary screw compression technology with an integrated Variable Frequency Drive (VFD) system. The VFD adjusts motor speed according to compressed air demand within its designed operating range. This variable-speed operating arrangement is particularly relevant for applications where compressed air consumption changes throughout the production cycle. Instead of relying exclusively on fixed-speed load/unload operation, the compressor can adjust its operating speed to respond to variations in system demand. The SJ RV10 is suitable for evaluating in applications such as CNC machining, automotive workshops, spray painting operations, pneumatic control systems and assembly lines with fluctuating compressed air requirements. Manufactured and supplied by Sarv Jagat Corporation in Ahmedabad, Gujarat, India, the SJ RV10 is part of the SJ variable-speed industrial screw air compressor range. Why Choose This Capacity? A 10 HP VFD screw air compressor is generally considered for smaller industrial facilities, individual production sections and machinery groups requiring a controlled compressed air supply. The SJ RV10 provides a specified airflow of 34 CFM (0.96 m³/min) at 10 bar, making it a capacity option for applications where both the required pressure and airflow are within the compressor's rated operating capability. Key capacity considerations include: • Variable Air Demand: Suitable for evaluating applications where compressed air consumption changes during different production cycles. • Controlled Pressure Supply: VFD technology adjusts motor speed to respond to changes in compressed air demand within its designed operating range. • Small Industrial Installations: Can be considered for workshops, individual manufacturing sections and smaller pneumatic production systems. • Precision Applications: Relevant for processes where maintaining a stable compressed air pressure is important. • Intermittent Machine Usage: Can be evaluated for machinery that operates with varying air consumption rather than maintaining a constant demand. • Capacity-Based Selection: The 34 CFM rated airflow should be compared with actual average and peak compressed air consumption before selecting the compressor. The SJ RV10 should be selected according to actual machinery requirements, operating pressure, peak airflow demand and the compressor's specified operating range. Important pressure-selection consideration: The SJ RV10 has different specified airflow capacities at different pressure ratings: • 8 Bar: 46 CFM (1.31 m³/min) • 10 Bar: 34 CFM (0.96 m³/min) • 13 Bar: 30 CFM (0.85 m³/min) Higher operating pressure generally requires more compressor energy. Therefore, 10 bar should be selected only when the connected machinery or process genuinely requires this pressure. If the application can operate reliably at a lower pressure, evaluating a lower-pressure configuration may help avoid unnecessary energy consumption. Advanced Rotary Screw Compression Technology The SJ RV10 uses single-stage rotary screw compression technology to generate compressed air for industrial applications. Rotary screw compressors use two intermeshing helical rotors to compress incoming air within the compression chamber. As the rotors rotate, air enters the compression element, becomes trapped between the rotor profiles and is progressively compressed before discharge. In a typical oil-injected rotary screw configuration, compressed air passes through an air-oil separation system and downstream cooling arrangement before entering the compressed air network. Key technology considerations include: • Rotary Screw Compression: Uses a rotating screw element to generate compressed air for industrial applications. • Single-Stage Compression: Uses a single compression stage as specified for the SJ RV10 model series. • VFD-Based Motor Control: Combines rotary screw compression with variable-speed motor operation. • Air-Oil Separation: In oil-injected configurations, the separation system reduces oil carryover from compressed air before downstream treatment. • Cooling and Temperature Management: Cooling systems help manage operating temperatures within the compressor. • Industrial System Integration: Can be integrated with a suitably selected air receiver, air dryer, moisture separator and filtration equipment. The final compressed air quality depends on the compressor configuration, downstream treatment equipment, installation conditions and maintenance practices. Applications requiring specific air purity levels must be designed around the relevant compressed air quality requirements. Variable Frequency Drive (VFD) Technology The SJ RV10 incorporates Variable Frequency Drive technology to adjust motor speed according to compressed air demand within its designed operating range. A VFD controls the electrical frequency supplied to the motor, allowing the motor speed to change instead of operating continuously at one fixed rotational speed. When compressed air consumption decreases, the VFD can reduce motor speed. When demand increases, the system can increase motor speed within its permitted operating range to respond to the changing requirement. Key VFD operating characteristics include: • Variable Motor Speed: Adjusts motor speed according to compressed air demand within the designed operating range. • Demand-Based Airflow: Compressor output changes as motor speed changes. • Pressure Regulation: Supports pressure control by adjusting compressor speed according to system requirements. • Partial-Load Operation: Can reduce unnecessary energy consumption when demand is lower than the compressor's maximum operating capacity. • Reduced Load/Unload Cycling: Variable-speed operation can reduce reliance on conventional fixed-speed load/unload cycling, depending on system demand and controller settings. • Controlled Motor Starting: VFD-based starting can provide a controlled acceleration profile, subject to drive configuration. • Application Flexibility: Relevant for production systems where compressed air consumption changes throughout the operating cycle. Potential energy benefits depend on the actual demand profile, pressure settings, operating hours, leakage, compressor operating range and system design. A VFD does not guarantee a fixed energy-saving percentage in every installation. For applications with consistently high and stable compressed air demand, a fixed-speed compressor may also be worth evaluating. The final selection should be based on a comparison of the expected operating profile and lifecycle electricity costs. Premium Industrial Components The performance and service life of a VFD rotary screw air compressor depend on the quality, compatibility and maintenance of its mechanical, electrical and cooling components. The SJ RV10 configuration can include the following functional systems, subject to the final supplied specification: • Rotary Screw Airend: The main compression assembly responsible for compressing incoming air. • Industrial Electric Motor: Supplies the mechanical power required to drive the compression system. Motor compatibility with the VFD, efficiency class, protection rating and insulation class should be confirmed from the approved technical specification. • Variable Frequency Drive: Controls motor speed by adjusting the electrical frequency supplied to the motor according to system demand. • Air Intake Filter: Filters incoming atmospheric air before it enters the compression system. • Oil Filter: Removes contaminants from the lubricating oil circuit to support proper lubrication. • Air-Oil Separator Element: Separates lubricating oil from compressed air in an oil-injected compressor configuration. • Lubricating Oil System: Supports lubrication, sealing and heat transfer within the compression system. • Oil Cooler: Helps regulate lubricating oil temperature during compressor operation. • Aftercooler: Reduces compressed air temperature downstream of the compression stage, subject to the supplied cooling arrangement. • Electrical Control Panel: Houses the electrical control and protection components required for compressor operation. • Compressor Controller: Provides operating information and control functions according to the installed controller configuration. • Acoustic Enclosure: Helps reduce operating noise and protects internal components, where included in the supplied model configuration. The exact airend, motor, VFD, controller, drive arrangement and component brands should be confirmed in the approved quotation and technical documentation. Component selection may vary according to the final compressor configuration. Reliable Industrial Performance The SJ RV10 is designed for industrial users evaluating a variable-speed compressed air solution for applications with changing airflow requirements. Its 10 HP motor rating and specified airflow of 34 CFM (0.96 m³/min) at 10 bar make it relevant for smaller industrial systems where pressure requirements remain important but compressed air consumption varies throughout the operating cycle. The VFD system allows the compressor to adjust motor speed according to demand within its designed operating range. This can help match compressed air production more closely with actual consumption and reduce unnecessary full-speed operation during periods of lower demand. However, reliable and economical operation depends on selecting the correct compressor capacity and operating range. A properly engineered installation should consider: • Actual compressed air consumption of connected machinery. • Average and peak airflow demand. • Required operating pressure at the point of use. • Variations in air consumption during production cycles. • VFD operating range and motor compatibility. • Pressure losses across pipelines, filters and air treatment equipment. • Air receiver capacity and pressure control strategy. • Ambient temperature and compressor room ventilation. • Required compressed air quality for each application. • Preventive maintenance requirements and replacement component availability. • Future production expansion and additional compressed air demand. For applications with frequent variations in compressed air consumption, the SJ RV10 can be evaluated as a variable-speed compressor option. The final selection should be based on measured or calculated demand rather than assuming that VFD technology automatically produces energy savings in every operating condition. Sarv Jagat Corporation provides industrial screw air compressor solutions along with associated compressed air equipment, spare parts and service support. The SJ RV10 can be evaluated as part of a compressed air installation designed around the actual pressure, airflow and operating requirements of the facility. Heavy Duty Cooling System The SJ RV10 is designed for industrial compressed air applications where effective temperature management is important for reliable compressor operation. During compression, air and lubricating oil temperatures increase. The cooling system helps manage these temperatures and maintain suitable operating conditions for the compressor components. The cooling arrangement may include: • Oil Cooling System: Helps regulate lubricating oil temperature during compressor operation. • Compressed Air Aftercooler: Reduces the temperature of compressed air before it enters the downstream air treatment system, where included. • Cooling Fan: Supports heat removal from the compressor enclosure. • Ventilation Arrangement: Helps circulate cooling air through the compressor. • Temperature Monitoring: Controller-based temperature monitoring and alarms, subject to the installed controller configuration. The compressor should be installed in a properly ventilated area with sufficient clearance for cooling airflow and routine maintenance. Hot cooling air should not be allowed to recirculate into the compressor intake or cooling system. The final cooling arrangement should be confirmed according to the supplied compressor configuration and installation conditions. Intelligent Electrical & Safety Features The SJ RV10 uses VFD-based motor control to adjust compressor speed according to compressed air demand within its designed operating range.

40 HP 8 Bar Variable Speed Rotary Screw Air Compressor The Sarv Jagat SJ RV40 is a 40 HP (30 kW) industrial variable speed rotary screw air compressor, engineered for manufacturing facilities and industrial operations requiring a higher-volume compressed air supply with variable demand control. Operating at a rated pressure of 8 Bar, the SJ RV40 delivers 184 CFM (5.21 m³/min) of rated airflow. Its Variable Frequency Drive (VFD) technology adjusts compressor motor speed according to changing compressed air demand, helping match air production more closely to actual consumption. The 40 HP capacity makes the SJ RV40 suitable for medium-to-large manufacturing facilities operating multiple pneumatic machines, automated production lines and air-operated industrial equipment. It is particularly relevant to installations where compressed air consumption varies throughout production shifts or between different processes. Combining rotary screw compression technology with variable speed motor control, the SJ RV40 provides an industrial compressed air solution for businesses seeking flexible air delivery, controlled operation and reliable production support. Why Choose This Capacity? The 40 HP compressor category is suitable for industrial facilities with substantial compressed air requirements, multiple connected machines and production processes that demand a higher airflow capacity. With a rated airflow of 184 CFM at 8 Bar, the SJ RV40 can support a range of pneumatic applications, provided that their combined operating demand remains within the compressor's available capacity. The 40 HP VFD configuration is particularly relevant to facilities where compressed air consumption changes according to production schedules, machine operating cycles and varying pneumatic loads. Unlike a conventional fixed-speed compressor that generally regulates air production through load/unload operation, the VFD system can adjust motor speed within its designed operating range to respond to changing air demand. Key capacity advantages: • 40 HP / 30 kW motor rating for demanding industrial compressed air requirements. • Rated airflow of 184 CFM (5.21 m³/min) at 8 Bar. • Variable speed operation for fluctuating compressed air consumption. • Suitable for multiple pneumatic machines and production equipment. • Helps reduce unnecessary unloaded operation under suitable operating conditions. • Greater operating flexibility for facilities with changing production loads. • Suitable for medium-to-large manufacturing and industrial installations. The correct compressor capacity should be selected using actual compressed air consumption, peak demand, required working pressure and future production requirements. Motor HP alone is not sufficient to determine whether a compressor can support a particular plant. Advanced Rotary Screw Compression Technology The SJ RV40 uses rotary screw compression technology, in which two precision-engineered helical rotors rotate inside a compression element to progressively compress incoming atmospheric air. As the rotors turn, air enters the compression chamber, becomes trapped between the rotor profiles and casing, and is compressed as the available volume decreases. Rotary screw compressors are widely used in industrial environments where a continuous and relatively stable compressed air supply is required. The compression system follows these principal operating stages: • Air Intake: Atmospheric air enters through the compressor's air intake and filtration arrangement. • Compression: The rotary screw airend compresses incoming air through the rotating screw elements. • Oil Injection and Separation: In an oil-injected configuration, lubricating oil supports sealing, lubrication and heat removal during compression. The downstream separation system separates oil from compressed air. • Cooling: The cooling arrangement manages heat generated during compression. • Air Delivery: Compressed air passes through the outlet connection into the connected compressed air distribution system. Variable Frequency Drive (VFD) Technology The SJ RV40 uses Variable Frequency Drive technology to regulate compressor motor speed according to compressed air demand. In a conventional fixed-speed compressor, the motor operates at a fixed speed, with air production generally controlled through load/unload operation. In a VFD compressor, motor speed can be adjusted within its permitted operating range to better match the required air output. When compressed air demand increases, the VFD can increase motor speed. When demand decreases, the drive can reduce motor speed, subject to the compressor's minimum and maximum operating limits. This operating method is relevant to industrial facilities where compressed air consumption changes throughout the working day due to production cycles, machine operation and varying pneumatic loads. Potential operating benefits include: • Better matching of compressor output with actual air consumption. • Reduced unnecessary unloaded operation under suitable demand conditions. • More controlled pressure regulation when correctly configured. • Greater operating flexibility for fluctuating compressed air requirements. • Potential reduction in electricity consumption compared with an appropriately comparable fixed-speed operating arrangement. Energy savings are not guaranteed at a fixed percentage. Actual performance depends on the compressed air demand profile, operating pressure, compressor control range, system leakage, installation conditions and annual operating hours. Premium Industrial Components The reliability and operating performance of an industrial screw compressor depend on its major mechanical, electrical and control components, together with correct system integration and preventive maintenance. The SJ RV40 is designed around an industrial compressor configuration incorporating the principal systems required for compressed air generation and variable speed operation. Rotary Screw Airend The screw airend is the main compression assembly. Its rotor profile, manufacturing precision, lubrication arrangement and operating conditions influence airflow performance, compression efficiency and service life. The airend must operate within its specified pressure, speed and temperature limits to maintain dependable performance. Industrial Electric Motor The electric motor drives the screw compression element and is selected according to the compressor's rated power and operating requirements. Important motor characteristics include rated power, insulation class, enclosure protection, cooling arrangement and efficiency rating. The final motor specification should be confirmed against the supplied configuration. Variable Frequency Drive The VFD controls motor speed according to compressed air demand. Correct drive selection, parameter configuration, electrical protection and cooling are essential for reliable variable speed operation. Air Filtration System The air intake filter helps prevent dust and airborne contaminants from entering the compression element. Regular filter inspection and replacement help maintain suitable intake conditions and reduce the risk of contamination. Oil Filtration and Separation System The oil filter removes contaminants from circulating compressor oil. The oil-air separator element separates lubricating oil from compressed air before the air reaches the compressor outlet. Cooling System The cooling arrangement manages heat generated during compression and supports operation within the intended temperature range. Cooling system cleanliness and adequate ventilation are particularly important in industrial environments with elevated ambient temperatures or airborne dust. Industrial Control System The compressor controller supports operating control and monitoring functions according to the supplied configuration. Controller functions, alarm features and communication options should be confirmed in the final technical quotation.

Heavy Duty Cooling System The Sarv Jagat SJ RV40 is designed with an industrial cooling arrangement to manage the heat generated during the rotary screw compression process. During compression, air temperature increases as its volume is reduced. The compressor cooling system helps maintain suitable operating temperatures for the compression element, lubricating oil and other heat-generating components. The cooling arrangement supports: • Heat removal from the lubricating oil and compression system. • Temperature management during industrial operation. • Stable compressor operation within the specified operating limits. • Reliable performance when the cooling system is maintained correctly. For dependable operation, maintain sufficient ventilation around the compressor, keep cooling surfaces clean and inspect the cooling arrangement at recommended service intervals. High ambient temperatures, restricted airflow and accumulated dust can negatively affect cooling performance. Intelligent Electrical & Safety Features The SJ RV40 uses Variable Frequency Drive (VFD) technology to regulate compressor motor speed according to compressed air demand. The VFD adjusts motor speed within the compressor's designed operating range. This allows the compressor to respond to changes in air consumption instead of relying exclusively on fixed-speed load/unload operation.

175 HP 10 Bar SJ VFD Variable Speed Screw Air Compressor – SJ RV175 The SJ RV175 is a 175 HP (132 kW) industrial variable-speed rotary screw air compressor designed for large manufacturing facilities and industrial operations requiring high compressed air capacity at 10 bar pressure. With a specified airflow of 706 CFM (19.99 m³/min) at 10 bar, the SJ RV175 is intended for demanding compressed air installations involving multiple production lines, large CNC machining clusters, automotive manufacturing, industrial automation and centralized factory air networks. The compressor combines single-stage rotary screw compression technology with Variable Frequency Drive (VFD) operation. Its VFD arrangement adjusts motor speed according to compressed air demand within the designed operating range, allowing compressor output to respond to changes in plant consumption. In large industrial facilities, compressed air demand can fluctuate as machines start and stop, production lines change operating rates and different departments run simultaneously. A variable-speed compressor can help match air generation with these changing requirements. The SJ RV175 is designed for applications where the required operating pressure is 10 bar and the calculated airflow requirement is compatible with its rated capacity. KEY PRODUCT SPECIFICATIONS • Model: SJ RV175 • Compressor Type: Industrial Rotary Screw Air Compressor • Motor Power: 175 HP / 132 kW • Operating Pressure: 10 Bar • Pressure Equivalent: 145 PSI / 1 MPa • Rated Air Flow: 706 CFM • Metric Air Flow: 19.99 m³/min • Compression Stage: Single Stage • Operating Technology: Variable Speed • Drive Technology: Variable Frequency Drive (VFD) WHY CHOOSE THIS CAPACITY? A 175 HP industrial screw compressor is considered for installations with substantial compressed air consumption across multiple machines, production departments or process systems. The SJ RV175 provides a specified airflow of 706 CFM (19.99 m³/min) at 10 bar. Its capacity should be assessed against the actual compressed air demand of the plant, including simultaneous consumption, peak demand and future expansion requirements. 1. HIGH-CAPACITY COMPRESSED AIR GENERATION With a specified airflow of 706 CFM at 10 bar, the SJ RV175 can be evaluated for industrial facilities where the combined compressed air requirement is beyond the capacity of smaller compressor configurations. Potential applications include: • Large CNC and VMC machining clusters. • Automotive manufacturing and assembly plants. • High-capacity packaging and bottling facilities. • Industrial automation and robotic production systems. • Large engineering and fabrication facilities. • Chemical and process manufacturing plants. • Centralized compressed air installations. The actual suitability depends on the required airflow, minimum operating pressure, air quality and operating conditions. 2. VARIABLE AIR DEMAND MANAGEMENT Compressed air consumption in large manufacturing facilities is not always constant. For example: • Several production lines may operate simultaneously during peak production. • Individual departments may stop or reduce production at different times. • Pneumatic actuators and machinery may consume air intermittently. • Automated production systems may have different consumption patterns. • Shift changes can create variations in total compressed air demand. The VFD arrangement allows motor speed to be adjusted according to the configured control demand within the compressor's designed operating range. This makes variable-speed technology relevant to installations where compressed air consumption changes throughout the production cycle. 3. CENTRALIZED COMPRESSED AIR SYSTEMS Large manufacturing facilities often use centralized compressor rooms to supply several production departments through a common compressed air distribution network. The SJ RV175 can be evaluated as a primary compressed air source where the calculated plant demand is compatible with its rated capacity of 706 CFM at 10 bar. Centralized system design should consider: • Total connected equipment demand. • Simultaneous operating airflow. • Average and peak compressed air consumption. • Required pressure at the point of use. • Air receiver capacity. • Pipeline diameter and pressure losses. • Air leakage across the distribution network. • Required compressed air quality. • Future production expansion. A compressor should not be selected only by adding the nominal air consumption of every connected machine. Actual simultaneous demand and operating patterns should be assessed. 4. 10 BAR INDUSTRIAL PRESSURE REQUIREMENT The SJ RV175 is specified for a 10 bar operating pressure configuration. This pressure should be selected when the connected machinery and production processes genuinely require it. Before choosing a 10 bar compressor, evaluate: • Minimum pressure required by production machinery. • Pressure losses across filters and dryers. • Pipeline pressure drop between the compressor room and points of use. • Required pressure at the most distant machine. • Pressure fluctuations during peak consumption. • Possibility of reducing system pressure through improved distribution design. Operating at a higher pressure than necessary can increase electricity consumption. The system should therefore be designed around the minimum pressure that reliably satisfies production requirements. ADVANCED ROTARY SCREW COMPRESSION TECHNOLOGY The SJ RV175 uses single-stage rotary screw compression technology for industrial compressed air generation. A rotary screw compressor uses two intermeshing helical rotors inside a compression element. Air enters through the intake side, becomes trapped between the rotor profiles and casing, and is compressed as it moves towards the discharge side. This continuous compression process is suitable for industrial installations requiring substantial compressed air capacity. PRINCIPAL COMPRESSION PROCESS 1. AIR INTAKE Ambient air enters through the compressor's air intake arrangement. An intake filtration system helps reduce the entry of dust and airborne particles into the compression system. The intake filter requires regular inspection and maintenance according to the operating environment. Dust accumulation can restrict airflow and increase pressure drop across the filter. 2. ROTARY SCREW COMPRESSION The compression element uses two rotating screw rotors to reduce the volume of trapped air and increase its pressure. The compressor's single-stage compression arrangement is designed to deliver compressed air according to the selected operating pressure configuration. 3. LUBRICATION AND INTERNAL COOLING For an oil-injected rotary screw configuration, lubricating oil performs several functions within the compression process. These functions generally include: • Lubrication of moving components. • Sealing between rotor clearances. • Absorption and removal of heat generated during compression. • Supporting the operating conditions of the compression element. The exact oil circuit and component arrangement depend on the supplied compressor configuration. 4. AIR-OIL SEPARATION In an oil-injected screw compressor, compressed air leaving the compression element contains oil that must be separated before the air is delivered to the downstream system. An air-oil separation arrangement reduces oil carryover in the compressed air stream. The separator element requires inspection and replacement according to the manufacturer's maintenance schedule and actual operating conditions. 5. COMPRESSED AIR DISCHARGE After the separation and cooling stages included in the supplied configuration, compressed air is discharged towards the downstream compressed air installation. Depending on the system design, downstream equipment may include: • Air receiver tank. • Moisture separator. • Refrigerated or desiccant air dryer. • Compressed air filters. • Distribution piping. The required treatment arrangement depends on the application and specified compressed air quality. VARIABLE FREQUENCY DRIVE (VFD) TECHNOLOGY The SJ RV175 uses Variable Frequency Drive technology to regulate motor speed according to compressed air demand within its designed operating range. This is relevant for large industrial installations where compressed air consumption can change significantly during production. Unlike a conventional fixed-speed arrangement, where the motor operates at a substantially fixed speed during loaded operation, a VFD compressor can vary motor speed by adjusting the electrical frequency supplied to the motor. HOW VFD CONTROL WORKS 1. PRESSURE MONITORING The compressor control arrangement monitors system pressure through its configured pressure feedback system. 2. DEMAND RESPONSE When compressed air consumption increases, system pressure can decrease. The control system can increase motor speed within the permitted operating range to respond to the increased demand. 3. SPEED ADJUSTMENT When compressed air consumption decreases, the control system can reduce motor speed within the designed operating limits. 4. AIRFLOW REGULATION Changing motor speed changes compressor output. This allows air generation to respond to variations in system demand. 5. PRESSURE CONTROL The VFD and controller work together to regulate compressor operation according to configured pressure settings and control parameters. OPERATIONAL RELEVANCE IN LARGE INDUSTRIAL PLANTS Consider a large manufacturing facility operating multiple production departments. During peak production, CNC machines, automated assembly systems, pneumatic fixtures and packaging lines may operate simultaneously. At other times, some departments may reduce production or stop individual machines. Consequently, total compressed air consumption changes throughout the day. A variable-speed compressor can adjust motor speed to respond to these changes within its designed operating range. POTENTIAL OPERATIONAL BENEFITS • Variable Output: Compressor airflow can be adjusted according to demand within the designed operating range. • Demand Matching: Helps match compressed air generation with changing plant consumption. • Pressure Regulation: Supports pressure regulation through the configured VFD and controller arrangement. • Reduced Load-Unload Cycling: Can reduce reliance on conventional load-unload cycling under suitable operating conditions. • Partial-Load Operation: Can reduce unnecessary full-speed operation when plant demand is below the compressor's available capacity. • Centralized System Integration: Can be evaluated for compressed air networks with changing demand. VFD ENERGY CONSUMPTION CONSIDERATIONS A VFD does not guarantee a fixed percentage of electricity savings. Actual energy performance depends on: • Daily compressed air demand profile. • Average operating load. • Required system pressure. • Compressor operating range. • Air leakage throughout the distribution network. • Number of operating compressors. • Control strategy. • Operating hours. • Maintenance condition. The greatest potential for energy reduction generally exists where compressed air demand varies sufficiently and the compressor can operate efficiently across the required range. If the plant operates continuously near full compressor capacity, the energy advantage over a correctly selected fixed-speed compressor may be limited. For this reason, a demand assessment and comparison of specific power consumption under actual operating conditions are recommended before making an energy-saving estimate. PRESSURE-WISE AIRFLOW CONFIGURATIONS The official SJ specification sheet lists different airflow capacities for the SJ RV175 at different pressure configurations. • 8 Bar: 883 CFM / 25.01 m³/min • 10 Bar: 706 CFM / 19.99 m³/min • 13 Bar: 636 CFM / 18.01 m³/min For this product page, the applicable configuration is: SJ RV175 – 175 HP – 10 Bar – 706 CFM – 19.99 m³/min. The airflow figures for 8 bar and 13 bar must not be used as the rated airflow for the 10 bar configuration.
