CompAir Oil-Free Rotary Screw Compressor - D Series

 

CompAir Compression Element

100% Oil-Free Compressed Air - Guaranteed Non-contact, non-wearing labyrinth seals prevent bearing lubricant entering the compression chamber. The design also features heavy duty, low friction ball and roller bearings and helical drive and timing gears. Thrust balance pistons equalise the loads across the bearings, allowing each bearing to achieve its optimum life expectancy.

 

DH Series - A Reliable and Efficient Heart

At the heart of the compressor is an innovative single screw compression element, featuring a single main rotor with 6 flutes meshing with a pair of 11 tooth gate rotors, that is proven in thousands of installations.

 

Compression takes place in two chambers above and below the main rotor, as a result compression loads are balanced and bearing loads are significantly reduced. The low bearing loads extend compression element life and significantly reduce lifetime operating costs.

 

Water injected into the compression element provides lubrication, sealing and cooling. The superior cooling properties of water allows the compressor to operate at a low temperature providing near isothermal compression, low power consumption and class leading efficiency levels. A reverse osmosis membrane cartridge filters the injection water entering the compressor; as a result the water is always maintained at a high purity level.
