Which compressor for your gas? Get a spec-ready answer in 60 seconds.
Enter your gas and duty conditions. Our rule base screens every machine type against its published envelope — pressure, differential pressure, capacity, staging and discharge temperature — then generates an RFQ-ready specification sheet you can send to any manufacturer.
Pre-selection reports are engineering aids, not final specifications — machine selection, materials, staging and safety classification must be confirmed with the manufacturer's engineering team.
Scope: positive-displacement process gas compressors (diaphragm, piston, dry and oil-injected screw, liquid ring, Roots). Centrifugal and axial machines are deliberately out of scope — when your duty points there, this tool tells you so rather than guessing.
This is a free tool supported by Chinese manufacturing partners: on request, we can forward your inquiry to compressor manufacturers we work with — that is how this tool stays free. We do not endorse, warrant, or act as agent for any manufacturer; supplier evaluation and due diligence remain your sole responsibility.
