Oil Free Air Compressor by Halward

Oil-free technology delivers many benefits Where contaminated compressed air can result in expensive product spoilage, you can rest assured that a CompAir oil-free compressor will eliminate oil-carryover in the compressed air supply. In addition, the removal of oil from the compression process enables compressed air users to operate with maximum environmental efficiency.

CompAir have been designing, manufacturing and supplying oil-free compressors for more than 90 years.

CompAir‘s D-range of compressors generate the highest quality oilfree air and have been certified ISO 8573-1 Class Zero (2010) and silicone free, making them the ideal choice for manufacturing processes where air is in direct contact with the product or sensitive equipment. 

CompAir compression element – 100 % oil-free compressed air, guaranteedNon-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.

Excellent efficiency The CompAir compression element design sets the industry standard for energy efficiency. Advanced asymmetric rotor profiles and optimised radial and axial porting ensure maximum air output for minimum energy consumption.The rotor casings feature generously-sized liquid cooling passages for even heat dissipation, enabling closer tolerances to be used for high compression efficiency.

Extended service lifeFor the longest working life, the correct lubrication and cooling of gears and bearings under all conditions is essential. For this reason, the CompAir D-range features an electric motor-driven oil pump that delivers full lubricant pressure prior to starting and during the stopping phases, thereby extending the operating life of the compression element. 

Two-stage inlet filtration protects against the ingress of airborne particles into the compression elements. Filter element life is extended by the enclosure mesh panel filters. This also ensures that the motors and coolers operate with the maximum cooling capability.
