How do Oil Free Compressors Work?
Oil-free rotary screw compressors utilize oil for lubrication of bearings and gears, which are isolated from the compression chamber. The lubricating oil, therefore, does not cause compressed air contamination.
Oil Free Air Compressors are used when there is a need to meet the Highest Air Purity Standard
Air purity is critical for many applications where even the tiniest drop of oil, or air contaminated with oil can cause product spoilage, product recall or damage production equipment.
Various industries have developed stringent quality standards to ensure safety of both manufacturing processes and end customers. Oil Free compressors are guaranteed to meet ISO 8573-1 Class Zero.
Oil-free air compressors can be the perfect solution for the compressed air applications where meeting the highest air purity standards is key. A 100% dry oil-free air supply can be achieved with the use of a number of different oil-less compressor technologies such as scroll, water injected screw , 2 stage dry screw, depending on your requirements.
