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.
Complete Unit	N/A Ready for operation Fully automatic Super-soundproofing Vibration-dampened Service-friendly design
Airend	N/A Two-stage, oil-free compression rotary screw compressor with precision gearing as per AGMA Q13/DIN- 5 2nd compression stage uses stainless steel rotors and jacket cooling Rotors feature durable coating Integrated oil tank with oil tank ventilation Fiber-free pulsation dampeners downstream of both compression stages
Drive Motor	N/A Manufactured by SIEMENS Premium and Super Premium Efficiency Motor Continuous motor winding temperature monitoring Enclosure protection: IP 55
Cooling	N/A Generously sized compressed air aftercooler with stainless steel precooler and aluminum cooler Reliable compressor performance up to 115 °F Aluminum cooler for gear oil

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 desired hot air temperature can be controlled in ranges.
