What is Diaphragm Compressor ?
Diaphragm compressors are classified from reciprocating compressors.
A diaphragm compressor is a specially constructed volumetric compressor that uses a rotating diaphragm to compress air or gas. The rotating diaphragm helps to deliver air or gas within the compression chamber and applies the required pressure to deliver air in the desired area.

The cylinders are highly sealed, no lubrication is required, and the compressed gas medium avoids contact with any lubricant, so diaphragm compressors can compress gases of very high purity, typically up to 99.999% purity. Diaphragm compressor is especially suitable for the compression, transport, bottling of precious and rare gases, in addition to extremely corrosive, toxic, flammable and explosive, radioactive gases, also suitable for the use of diaphragm compressor.
Why Choose Minnuo Diaphragm Compressor?
Established in 1987, Min Group has been developing and manufacturing industrial diaphragm gas compressors. They are the preferred equipment for high purity, hermetic gas lift compression for hydrogen fuel stations, chemicals, oil, and gas, etc. We have developed H, D, L, V, and Z models and more than 30 product series for intelligent diaphragm gas compression systems.
We can design and manufacture full instrumentation oil-free reciprocating diaphragm gas compression systems according to customer requirements.
Sizes range from 3 hp (2 kW) – 250 hp (186 kW). Output pressures range from 50 psi- 45,000 psi (3,100 bar).
