When is piston better than screw?
High pressure at modest flow, intermittent duty, or process gases screws cannot swallow. Put the duty, not the preference, on the RFQ.
Technology
Piston packages in China run from workshop portables to API-style process recips. Those are not one RFQ. Write pressure stages and whether the air must be oil-free.
Specification
A 12 bar two-stage piston for a workshop is a different factory from a hydrogen diaphragm or a process recip. Put the number of stages, lubrication, and the gas on the sheet.
Listed plants with piston series are matched from published rows. Portable piston and industrial piston should not share a shortlist unless you meant that.
RFQ points
Missing nameplate fields on catalog rows stay confirm-on-RFQ. We do not fill them in to look complete.
Listings below are Chinese manufacturing plants drawn from public factory data and files we hold. A row is not exclusive agency, not a “verified factory” badge, and not a claim the plant appointed CompressorB2B. Plants that finish onboarding receive RFQs in the factory desk.
Matching plants
The plant remains the seller. Quotes are comparable because the RFQ is the same sheet.

FAQ
High pressure at modest flow, intermittent duty, or process gases screws cannot swallow. Put the duty, not the preference, on the RFQ.
Piston compressor manufacturers in China: Voltage and frequency matter as much as bar. Typical first reply: 1–2 working days after the plant confirms it can hold the duty.
