Oil-free and oil-less technology are used in a variety of applications across the globe. Hospitals, pharmaceuticals, the food industry, among many others depend on Gardner Denver to provide the cleanest, oil-free air for their systems and processes.
In a lubricated machine oil is used to seal, lubricate and cool, however this then leaves high oil content in the compressed air that has to be removed. Oil free compressor, or oil less compressors, use an alternative medium such as water to seal, lubricate and cool, or compression takes place in multiple stages, the compressor then delivers the highest quality air without the need for separation and filtration. The types of technologies used in oil free compressors include, Water Injected compressors, two stage dry screws, single or two stage oil free pistons or centrifugal compressors.
Gardner Denver offers a wide variety of oil-free and oil-less technologies including a two stage dry screw capable of pressures over 150 psig and a water injected single screw compression element that provides a system package 100% free of oil, completely eliminating the possibility of oil contaminating the system. This technology makes Gardner Denver an industry leader in providing oil free compressed air. In an oil-free machine, the air is compressed entirely through the action of the screws, without the assistance of an oil seal. They usually have lower maximum discharge pressure capability as a result. However, multi-stage oil-free machines, the air is compressed by several sets of screws. Oil-free machines are used in applications where entrained oil carry-over is not acceptable.
