What Clients Say

Since 2006, we have ordered more than 40 sets oil free air compressor from CMN. The compressed air is direct contact with drugs so we have strict requirements in terms of moisture content, oil content and microbial content. With our first corporation with CMN, we surprisingly find that they have passed all tests according to requirements of GMP, WTO certifications and also has features of lower noise, higher efficiency and higher stability compared with dry oil free compressor we used before.

Hisun Pharmaceutical Co., Ltd.

We used first set of CMN oil free compressor in 2010, and gradually purchased 6 sets more. The earliest machine has reached operation time of 50000 hours and has no failure yet. We were using dry oil free compressor of a famous international brand before we know CMN, CMN has reduced countless maintenance cost for us and we believe water lubricated compressor is definitely a cut edge invention.

Zhejiang Conba Pharmaceutical Co., Ltd.

CMN is an innovative company, they have launched a lot of products that no company had ever manufactured before and help to promote the development of the industry. We had purchased more than 10 sets of CMN oil free low pressure air compressor in manufacturing the glass bottle, machines are running well so far with great features of low noise, low energy consumption and low maintenance cost.

Oil Free Compressor VS Oil Injected Compressor

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.

What Is Better Oil Free Compressor Or Oil Injected Compressor?

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.
