Diaphragm Compressors Manufacturer

Gl2-50/7-160 CHMembrane Compressors

DSW has been manufacturing diaphragm compressors for industrial gas worldwide since 2007. Our comprehensive lineup of air compressors can compress a range of gases such as argon, carbon dioxide, carbon monoxide, deuterium, ethylene, fluorine germane helium hexafluoropane hydrogen krypton methane neon nitrogen oxygen polypropylene silane sour syngas tetrafluoromethane xenon gas mixtures, etc.

Ideal for precision gas applications that require high pressure.

air compressors in all sizes and for all applications

DSW Diaphragm compressors are the ideal choice for hydrogen recovery and fueling stations. Our hydrogen compressors are designed and manufactured in-house using static metal seals that ensure safety & reliability up to 7,000 psig & 10,000 psig.

What is a reciprocating compressor?

A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure. Pressures of up to 5,000 PSIG are commonly produced by multistage reciprocating compressors.
