Additional Information N/A
  • Robust stainless steel-aluminum cooler combination
  • All models available with i.HOC® integrated heat of compression dryer
Advantages N/A
  • Heat-recovery made easy - Thanks to radial fans with high residual thrust, the heated exhaust air can easily be ducted away and used for heating an adjacent room without additional auxiliary fans.
  • Energy-efficient features - In standby mode, the temperature-controlled Kaeser standstill fan reliably dissipates residual heat. This allows the main fan to turn off and cools the package down for quicker service.
  • Exceptionally maintenance-friendly - Swing-out coolers make cleaning easy.
Low Life Cycle Costs N/A Our custom consulting services, award-winning product design, and continual investment in our research and development give you superior quality that's tailored for your needs.

Hydraulic Inlet Valve N/A The hydraulic inlet valves in Kaeser's oil-free rotary screw compressors are unaffected by contamination and condensate. This makes them more reliable and easier to maintain than pneumatic valves.
Fiber-Free Pulsation Dampeners N/A Kaeser's new fiber-free pulsation dampeners keep pressure losses to an absolute minimum, help maintain consistent air quality and, unlike fiber versions, eliminate the possibility of compressed air contamination.
Reliable Oil Reservoir Venting N/A The microfilter in the oil tank venting system prevents the intake of oil-laden air. This ensures compressed air quality is maintained at all times.
Highly Efficient Condensate Separator N/A Thanks to its flow-optimized design, the newly developed condensate separator reliably separates the condensate downstream from the air coolers, and with minimal pressure loss.
Bolt-Down Machine Mounts N/A Machine mounts for bolting the unit to the floor
Silencer for Air Inlet Opening N/A Dampening louvers in front of heat exchangers
Cooling Air Filter Mats N/A
  • Cooling air filter mats in the inlet area of the compressor
  • Reduce build-up on heat exchanger surfaces and inlet air filters
Hot Air Connection N/A
  • Direct use of the hot compressed air, e.g. for heat regenerating desiccant dryer or as hot process air.
  • With certain models, the required hot air temperature can be controlled in ranges.
