The CompAir WS range of water sealed oil-free screw compressors.

With the requirement for high quality oil-free air no longer the sole preserve of the pharmaceutical, medical, food and electronics industries, engineers have been searching for a system which will supply air to increasingly stringent international purity standards without the drawbacks associated with today’s oil-free compressors.

Now CompAir has the answer
CompAir WS water sealed oil-free screw compressors have none of the inherent disadvantages on conventional oil-free plant. No expensive inter-cooling or after cooling equipment is required.

Simplicity of design and construction means there are less moving parts. The use of advanced materials provides spectacular output gains and means there is no oil anywhere in the system while the condensate - pure water - can be piped directly into the mains drainage system.

CompAir can now offer what engineers have been searching for - a more effective and reliable source of oil-free air for industry


More Energy Efficient
CompAir WS compressors provide an output improvement of up to 15% over the move traditional piston, hook compression and oil-injected rotary screw plant. The key to this improvement lies in the revolutionary cooling and lubricating system.

At the heart of the compressor are two rotors made from a high quality ceramic material which is impervious to corrosion or wear. The use of this almost indestructible material means that water is used in place of oil in the compressor. The rotors operate within a rugged stator casing and water - the most natural of substances - is piped through the housing to cool and lubricate the rotors.

The heat produced during compression is dissipated almost immediately by the water passing along the rotors. This enables the compressors to operate at a very low temperature and means that less power is required to compress the air.

Energy efficiency is also improved via the water sealing process. Not only is water cleaner and cheaper than oil, but it has lower viscosity. The rotors meet less resistance than in oil-injected compressors and the power consumption on the CompAir WS compressor is reduced yet further.


Highly reliable and Ultra Quite
The effectiveness of the CompAir WS water cooling and lubrication system means that no internal gears, filters, inter-cooling or after-cooling equipment are necessary to provide a consistent supply of cool clean-room standard air.

This makes the WS one of the most reliable and quiet oil-free compressors on the market today. Normal conversation is possible in the plant room and expensive external sound proofing measures are unnecessary. The compressor itself makes ess noise than the electronic motor which powers it.


Minimal Maintenance
The very simple single stage screw design of the CompAir WS range means it has less moving parts and ancillary items than any other comparable compressor. This results in longer component life, less compressor down-time and reduced maintenance costs. The ceramic rotors themselves are completely maintenance free.

Plant room safety is also improved. The almost instantaneous heat dissipation means that the compressor casing is cool to the touch, even at full load.


Environmental Benefits
The CompAir WS range of water sealed oil-free screw compressors will fit well within any ecological production porcess.

Not only is the possibility of oil contamination of the compressed air avoided, but there is no longer the problem of waste oil disposal. The condensate - pure water - can be piped direct from the compressor into the mains drainage system.
