Delivering a rated airflow of 1,035 CFM (29.30 m³/min) at 8 bar pressure, this model is designed to support demanding pneumatic operations, multiple production departments and large industrial utility networks. Equipped with Variable Frequency Drive (VFD) technology, the SJ RV220 adjusts compressor motor speed according to changing compressed air demand within its designed operating range. This demand-responsive operation makes it suitable for facilities where air consumption varies with production schedules, machinery cycles and simultaneous equipment operation. Combining oil-injected rotary screw compression technology with variable speed control and industrial supporting systems, the SJ RV220 is designed for applications where high airflow capacity, controlled operating pressure and dependable compressed air availability are essential to production continuity. Why Choose This Capacity? A 220 HP screw compressor is intended for large industrial installations with substantial compressed air consumption. With a rated airflow of 1,035 CFM (29.30 m³/min) at 8 bar, the SJ RV220 can serve large centralised compressed air networks and multiple production areas when correctly sized for the plant's actual demand. This capacity can be considered for: - Large automotive and automobile component manufacturing complexes - Heavy engineering and industrial manufacturing plants - Large CNC machining facilities and automated production lines - Large textile mills and industrial processing facilities - Plastic processing and injection moulding plants - Industrial packaging and bottling production facilities - Large pharmaceutical and chemical manufacturing utilities - Centralised compressed air networks serving multiple departments - Heavy-duty manufacturing operations with high-volume pneumatic equipment - Industrial plants operating several compressed air-consuming processes simultaneously The VFD configuration is particularly relevant where compressed air demand changes throughout the operating day. By adjusting motor speed within its permitted operating range, the compressor can better match output to actual consumption rather than relying exclusively on fixed-speed load/unload operation. This may reduce unnecessary full-speed operation during lower-demand periods and improve energy management under suitable operating conditions. Actual energy consumption depends on the plant's load profile, operating pressure, leakage levels, compressor control range, installation conditions and total running hours. Energy savings should be evaluated using measured operating data rather than assumed percentages. For a compressor of this capacity, proper system planning is particularly important. The plant's average and peak airflow requirements, simultaneous machine demand, operating pressure at points of use, existing compressor capacity, future expansion and compressed air storage should be evaluated before selection. Correct sizing helps prevent inadequate air supply, excessive unloading or inefficient operation. Advanced Rotary Screw Compression Technology The SJ RV220 uses rotary screw compression technology, in which two precision-engineered screw rotors rotate inside the compression element to progressively compress incoming atmospheric air. This continuous compression principle is designed for industrial applications requiring substantial compressed air output over extended operating periods. In an oil-injected rotary screw compressor, compressor lubricant performs important functions within the compression element, including sealing, cooling and lubrication. The resulting air-oil mixture passes through an air-oil separation system, which separates lubricant from compressed air before it is delivered to the downstream compressed air network. Rotary screw technology is widely used in industrial compressed air systems because it is suited to continuous-duty applications and high-volume air generation. The SJ RV220 combines this compression arrangement with variable speed control to address industrial installations with changing air consumption. Key functional advantages include: - Continuous rotary screw compression for high-volume industrial air requirements - High airflow capacity for large manufacturing facilities - Oil-injected compression technology for sealing, cooling and lubrication - Integrated air-oil separation arrangement - Variable speed operation through VFD control - Compatibility with industrial air storage and treatment systems - Suitability for large centralised compressed air installations Variable Frequency Drive (VFD) Technology The SJ RV220 incorporates Variable Frequency Drive technology to regulate compressor motor speed according to compressed air demand. The VFD controls the electrical frequency supplied to the motor, allowing the compressor to adjust its operating speed within the designed minimum and maximum operating limits. A conventional fixed-speed compressor generally operates at a fixed motor speed and regulates output through load/unload operation. A VFD compressor can vary motor speed in response to changing air consumption, helping the compressor match its output more closely to the plant's demand profile. Key benefits of VFD operation include: - Demand-based motor speed adjustment - Compressor output regulation within the permitted operating range - Reduced unnecessary full-speed operation during lower-demand periods - Improved pressure regulation under suitable operating conditions - Potential reduction in unloading losses compared with conventional fixed-speed operation - Better adaptability to changing production requirements The actual energy benefit depends on compressed air consumption patterns, operating pressure, system leakage, compressor operating range, control settings and total running hours. VFD technology does not guarantee a fixed percentage of electricity savings in every installation. For accurate energy evaluation, the plant's compressed air demand profile and existing compressor operating data should be assessed before estimating potential savings. Premium Industrial Components The SJ RV220 is designed around industrial compressor components and supporting systems intended for high-capacity compressed air operation. Component makes and exact specifications should be confirmed in the approved technical quotation for the supplied machine. Compression Element: The rotary screw airend is the primary compression component. It draws atmospheric air into the compression chamber and progressively compresses it through the meshing movement of the screw rotors. Airend options may include approved industrial makes such as Baosi, Hanbell or an equivalent approved specification. Electric Motor: The compressor uses an industrial electric motor selected to drive the screw airend. Motor efficiency class, insulation class, enclosure protection and electrical ratings should be verified against the final machine configuration.

Correct drive sizing, electrical protection, cooling and parameter configuration are important for reliable variable speed operation. Air Intake Filter: The intake filtration system helps prevent dust and airborne particles from entering the compression element, reducing contamination and premature component wear. Oil Filtration System: The oil filter removes contaminants from the circulating compressor lubricant to support effective lubrication and protect internal compressor components. Air-Oil Separator: The separator element separates compressor lubricant from the compressed air-oil mixture before the air is supplied to the downstream system. Maintaining the separator in good condition is important for controlling oil carryover and supporting efficient compressor operation. Cooling Arrangement: The cooling system manages heat generated during compression and helps maintain suitable operating temperatures under specified installation and ambient conditions. Industrial Controller: The control system supports compressor operation, operating status indication, parameter monitoring and protective functions according to the selected controller configuration.

Its 220 HP motor rating and rated airflow of 1,035 CFM (29.30 m³/min) at 8 bar make it suitable for high-demand compressed air applications. The VFD control arrangement allows the compressor to respond to changes in air consumption by adjusting motor speed within its designed operating range. When correctly selected and integrated into the plant's compressed air network, this can support more controlled operation under fluctuating demand conditions. For dependable performance, the compressor should be installed with adequate ventilation, sufficient maintenance access, a suitable electrical supply, correctly sized air piping and an appropriate compressed air treatment system. Regular inspection and scheduled replacement of filters, separator elements and compressor oil are essential for maintaining operating reliability. At this capacity, downstream equipment selection is especially important. Air receiver tanks, dryers, filters, moisture separators and distribution piping must be appropriately sized for the actual airflow and pressure requirements. Undersized treatment or distribution equipment can cause excessive pressure drop and restrict the usable air supply at the point of consumption. Where the application requires dry or filtered compressed air, the SJ RV220 can be integrated with suitable refrigerated or desiccant air dryers, moisture separators and filtration stages. The required air treatment configuration depends on the end-use air quality specification and applicable process requirements.

40 HP 10 Bar SJ VFD Variable Speed Screw Air Compressor The SJ RV40 is a 40 HP industrial VFD screw air compressor designed for manufacturing facilities and industrial applications requiring a 10 bar compressed air supply with variable airflow demand. Powered by a 30 kW motor, the SJ RV40 delivers a specified airflow capacity of 138 CFM (3.91 m³/min) at 10 bar pressure. Its Variable Frequency Drive (VFD) technology adjusts motor speed according to compressed air demand within the designed operating range. Unlike a conventional fixed-speed compressor that operates at a fixed motor speed during loaded operation, the SJ RV40 can vary its motor speed to respond to changing air consumption. This makes it relevant for production environments where multiple machines and pneumatic systems have different operating cycles and compressed air requirements. The SJ RV40 combines single-stage rotary screw compression with variable-speed operation for industrial compressed air applications requiring controlled pressure and changing airflow demand. Why Choose This Capacity? Selecting an industrial air compressor requires more than matching the motor horsepower. The actual airflow requirement, operating pressure, simultaneous machine consumption and future production requirements must also be considered. The SJ RV40 provides: • Motor Power: 40 HP / 30 kW • Operating Pressure Rating: 10 Bar / 145 PSI • Rated Air Flow: 138 CFM / 3.91 m³/min • Compression Technology: Single-stage rotary screw • Operating Technology: Variable Speed with VFD The 40 HP capacity can be evaluated for medium to large manufacturing facilities, multi-machine production environments, machining clusters and automated industrial systems requiring a substantial compressed air supply. Its specified airflow of 138 CFM at 10 bar makes it relevant for applications where several machines operate simultaneously. However, the total demand of connected equipment must be calculated before selecting the compressor. The 10 bar pressure rating is relevant where the connected machinery or process genuinely requires this pressure level. If the application operates satisfactorily at a lower pressure, the lower-pressure compressor configuration should also be evaluated because operating at unnecessarily high pressure can increase electricity consumption. The SJ RV40 is particularly worth evaluating when compressed air demand changes throughout the production cycle. Examples include machining centres, automated assembly systems, packaging lines and manufacturing facilities with varying pneumatic consumption. Before selecting the compressor, calculate the combined airflow requirement of simultaneously operating machines and account for pressure losses across the air distribution and treatment system. Advanced Rotary Screw Compression Technology The SJ RV40 uses single-stage rotary screw compression technology for industrial compressed air generation. A rotary screw compressor uses two intermeshing helical rotors to compress air within the compression chamber. As air enters the compression element, it becomes trapped between the rotor profiles and housing. The reduction in trapped volume raises the air pressure before compressed air is discharged from the element. The principal functional systems of an oil-injected rotary screw compressor include: • Air Intake System: Supplies atmospheric air to the compression element through an intake filtration arrangement. • Screw Airend: Performs the compression process through the rotating screw elements. • Lubrication System: Circulates compressor oil for lubrication, cooling and sealing in an oil-injected configuration. • Oil Filtration System: Helps remove contaminants from the circulating lubricating oil. • Air-Oil Separation System: Separates lubricating oil from compressed air in an oil-injected configuration. • Cooling System: Helps manage heat generated during compression. • Control System: Coordinates compressor operation and monitors available operating parameters according to the supplied configuration. Rotary screw technology is widely used in industrial compressed air systems where production processes require a dependable source of compressed air. The actual air quality delivered to the factory network depends not only on the compressor but also on downstream air treatment, filtration, piping and condensate management. Variable Frequency Drive (VFD) Technology The SJ RV40 incorporates Variable Frequency Drive technology to adjust motor speed according to compressed air demand within its designed operating range. In a conventional fixed-speed compressor, the motor operates at a fixed speed during loaded operation. When system demand falls, the compressor generally regulates capacity through its load/unload control arrangement. In a VFD-controlled compressor, the drive changes the electrical frequency supplied to the motor, allowing the motor speed to vary. This enables the compressor to adjust its output according to changing compressed air consumption. Key operating advantages of VFD technology include: • Variable Motor Speed: Adjusts motor speed according to compressed air demand within the designed operating range. • Demand-Based Air Delivery: Helps match compressor output more closely to changing system consumption. • Pressure Control: Supports pressure regulation through the supplied controller and feedback arrangement. • Reduced Unnecessary Full-Speed Operation: Allows lower-speed operation when demand decreases, subject to operating limits. • Reduced Load-Unload Cycling: Can reduce reliance on repeated load/unload cycles under suitable operating conditions. • Potential Energy Savings: Lower motor speed during partial-load demand can reduce electricity consumption compared with fixed-speed operation in suitable applications. Actual electricity savings depend on the factory's air consumption profile, pressure settings, leakage, operating hours, compressor operating range and overall compressed air system design. A fixed energy-saving percentage cannot be guaranteed. VFD operation is particularly relevant for facilities where compressed air demand varies between production shifts, machine cycles or operating stages rather than remaining consistently close to maximum capacity. Premium Industrial Components A screw compressor's operating reliability depends on the quality and compatibility of its compression, lubrication, separation, cooling and electrical systems. The SJ RV40 is intended for industrial compressed air applications where these functional systems must work together as an integrated compressor package. Important component groups include: 1. Rotary Screw Airend The airend is the primary compression assembly. Its rotor design, operating speed, lubrication arrangement and compatibility with the motor and drive system influence the compressor's operating performance. 2. Electric Motor The motor supplies mechanical power to the screw compression element. Motor selection must be compatible with the compressor's rated power, electrical supply, VFD operating range and thermal requirements. 3. Air Intake Filter The intake filter helps prevent airborne dust and particulate contamination from entering the compression element. Regular inspection and replacement are important, particularly in dusty industrial environments. 4. Oil Filter The oil filter helps maintain lubricating oil cleanliness by removing contaminants from the circulating oil. 5.
