Kaeser's 20 HP Screw Compressor Models

Standard 20 HP Air Compressor

Kaeser's standard 20 hp screw compressor models in the SK and AS series offer impressive performance and quiet operation. They feature a robust design with super-silenced, vibration-dampening, and powder-coated panels, suitable for ambient temperatures up to +115 °F. The unit is equipped with an IE3 premium efficiency motor (IP 54) and an innovative dual-flow fan with separate airflow channels for efficient cooling of the motor, fluid/compressed air cooler, and control cabinet. Key fluid and airflow features include a 'Honeycomb' air intake filter, pneumatic inlet and venting valves, a triple-separation system in the cooling fluid separator tank, and comprehensive pressure and fluid management components.

20 HP Air Compressors with Integrated Dryers

SK 20T - 20 hp screw compressor with dryer

The SK 20T and AS 20T are rotary screw compressors with integrated refrigerated dryers sized for the full flow of the compressor. The dryer is located in a separate cabinet so it is not exposed to preheated air or contaminants from the compressor package.

Energy-Saving Control:

The integrated refrigerated dryer in "T” units provides high efficiency performance thanks to its energy saving control. The dryer is active only when compressed air actually needs to be dried. This approach achieves the required compressed air quality with maximum efficiency.

Eco-Drain:

The integrated refrigerated dryer also features a zero loss Eco-Drain. The advanced level-controlled condensate drain eliminates the compressed air losses associated with solenoid valve control. This saves energy and considerably enhances the reliability of the compressed air supply.

Climate-Friendly Design:

In addition to energy-saving controls, our integrated dryers feature the new R-513A refrigerant with 56% lower global warming potential than common dryer refrigerants. Combined with our advanced heat exchanger design, we need only half the refrigerant — resulting in the most climate-friendly dryer possible.

20HP Rotary Screw Compressor with Variable Speed Drive

kaeser sfc series 20 hp variable speed drive rotary screw compressor

The SFC 15 20-hp rotary screw compressors is the perfect solution for smaller compressed air systems with varying air demand to achieve significant energy savings while maintaining stable pressure. KAESER SFC units are up to 18% more efficient than the competition. The SFC 15T model has an integrated dryer. Learn more about Kaeser's SFC series of compressors with variable speed drive.

A variable speed screw compressor should be the most frequently loaded unit in a properly designed system. Each is optimized to deliver significantly more air with lower kW than comparable compressors.

Complete 20HP Compressed Air System
