ASK Series

At the heart of each HPC ASK series rotary screw air compressor is the specially designed airend with flow-optimised Sigma Profile rotors delivering more compressed air for less energy consumption. The efficiency of the airend is further complimented by a highly effective cooling system with dual-flow fan. This innovative design not only enhances cooling performance, but also minimises sound emissions. Furthermore, separate intake of motor-cooling air and air for compression from the ambient surroundings ensures optimum motor cooling and increased compression performance.

 

The internal “Sigma Control Basic” controller provides automatic system monitoring and precisely adjusts compressor performance to match actual compressed air demand. Models are also optionally available equipped with the “Sigma Control 2”, which allows connection to compressed air management systems.

 

These units are also exceptionally service-friendly: The housing cover on the left of each unit is easy to remove and allows excellent component accessibility, whilst the new maintenance-free drive belt between the motor and airend eliminates the need for intermittent belt tensioning and adjustment. This both guarantees optimum power transmission and reduces service costs.
