Can an oil-injected plant quote oil-free?
Only if they actually build that airend. We match on published oil-free series, not on a trading-company catalogue.
Technology
Oil-free screw compressor manufacturers in China
Oil-free screw is a different factory from oil-injected screw. Dry airends and water-lubricated airends are also different quotes. Name the architecture.
What belongs on the RFQ
Same sheet, matching plants
Chinese plants build dry oil-free screw and water-lubricated oil-free screw. Mixing them in one RFQ produces prices you cannot compare. Say which architecture the validation file allows.
ISO 8573-1 class, dryer and sterile housing belong on the same sheet as kW and bar. A food plant that only writes “oil-free China” will get an industrial dry screw without the paper trail.
Rows below are published oil-free series. Missing Class 0 reports are not invented.
- Dry screw or water-lubricated
- ISO 8573-1 class and test point
- Working pressure and FAD or kW
- Dryer / filter train
- Voltage / frequency
- Incoterm
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.

FAQ
Oil-free screw compressor manufacturers in China — buyer questions
Oil-free screw 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.
