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 allow 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.100% Oil-Free ConstructionLow operating temperatures and bearing loads enable maintenance free sealed bearings to be used, totally removing the need for lubricating oil in the compressor. 100% oil-free compression is therefore guaranteed and the maintenance and environmental costs associated with oil and oil filter changes are eradicated.The Comp Air range of oil-free compressors can be relied upon to deliver a consistent flow of high quality, clean and economical compressed air.
