Available from CompAir Australasia , the D Series rotary screw compressors are 100% oil-free and available in air-cooled and water-cooled options.

Providing oil-free compressed air, rotary screw compressors guarantee non-contact, non-wearing labyrinth seals that prevent bearing lubricant entering the compression chamber. 

Featuring heavy duty, low friction ball and roller bearings and helical drive and timing gears the compression element of D Series rotary screw compressors also feature thrust balance pistons to equalise the loads across the bearings, thus allowing each bearing to attain optimal life expectancy.

The compression element of D Series rotary screw compressors are designed for energy efficiency and the asymmetric rotor profiles and optimised radial and axial porting make sure optimum air output for low energy consumption. For high compression efficiency the rotor casings feature generously-sized liquid cooling channels for even heat distribution, enabling closer tolerances.

Correct lubrication and cooling of bearings and gears, under any condition, is vital for extending the life of oil-free rotary screw compressors. The CompAir D Series features an electric motor-driven oil pump that provides lubricant pressure prior to starting and during the stopping phases to combat this.

A two-stage inlet filtration function protects D Series rotary screw compressors against the intake of airborne particles into the compression elements. 

D Series oil-free rotary screw compressors are free standing and feature coolers, drive motor, silencing system, inlet filtration, integrated compressor controls and all service connections.
