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

"HPC Air Compressors Come Complete With A Fully Inclusive 5 Year 'No Quibble' Parts & Labour Warranty"

The HPC BSD series rotary screw compressors are the perfect partners for high efficiency industrial compressed air stations. The internal SIGMA CONTROL 2 compressor controller offers numerous communication channels, which allows seamless connection with advanced master controllers, such as KAESER’s SIGMA AIR MANAGER, and in-house centralised control systems. This enables simple set-up and achieves unprecedented levels of efficiency. 

The distinctive and eye-catching design of the HPC BSD series from the outside is complemented by intelligent component layout on the inside for even greater energy efficiency: All service and maintenance points are within easy reach and directly accessible. This saves both time and money when it comes to servicing.
