More than 20 years oil free compressor manufacturing experience
CMN brand has a history of more than 60 years.
The lubrication technique used to maintain an air compressor's air-end moving smoothly distinguishes oil-free air compressors from oil-filled ones. Oil-injected compressors are used in the majority of industrial air compressors due to their lower cost and longer lifespan compared to oil-free compressors.
The air end of a oil injected air compressor uses oil for lubrication, so the air end does not require maintenance. However, since oil-related accessories need to be replaced, the cost is relatively higher than oil free compressor. Using an oil-free air compressor can reduce the problem of waste oil disposal also.
