At the heart of each HPC ASD series direct drive rotary screw air compressor complete with integral refrigerant dryer 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.
