Oil free compressors are a subset of screw compressors. In this type of compressors, due to the absence of oil, compressed air is produced with proper quality and without pollution, and due to being free of oil in industries such as the production of electronic components, It is used for pharmaceutical, hospital, military, etc., for whom the exhaust air is important.
The reason is that the presence of a particle of oil in the exhaust air causes damage to the product produced in an industry such as the production of electronic components, and even more serious risks in the pharmaceutical and food industries, etc.
In these compressors, two Airend devices are used, which are more advanced in terms of the quality and lightness of the rotors compared to the air generator unit in oil inject compressors, and its internal material is made of Teflon.
In this type of oil free compressors, the output air is hotter than oil-injected compressors, and cooling devices must also be used, and in order to reduce the noise in the inlet and outlet openings, a muffler must be used. These compressors have lower pressure than oil compressors, but in terms of speed, due to the use of rotors or an air-generating unit that does not have oil, and also because the internal components are lighter, they have a higher speed than oil compressors.
