How to specify an air compressor

If the RFQ only says “compressor, China”, a plant cannot price it. Start with architecture, then the duty point, then the papers.

How to specify an air compressor · duty, not a SKU

What belongs on the RFQ

Write the duty point

Write working pressure in bar(g). Write FAD at that pressure, or the process that implies flow. Write motor kW or the site electrical limit. Write 50/60 Hz and voltage. Write oil-injected or oil-free and the ISO 8573-1 class if it matters.

Then quantity, destination, FOB China port or CIF named port, packing, and whether a third-party inspection is required before loading. That is a sheet a plant engineer can answer. A brochure comparison is not.

CompressorB2B is the English specification desk. We route that sheet to listed Chinese manufacturing plants. We do not take the PO.

  • Architecture (screw, oil-free, piston, centrifugal, PET, refrigeration, gas)
  • Working pressure in bar(g)
  • FAD at that pressure
  • kW or site limit, voltage, frequency
  • Certificates actually required
  • Quantity, inspection, 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.

The plant remains the seller. Quotes are comparable because the RFQ is the same sheet.

FAQ

Before you send the sheet

What if I do not know FAD?

Describe the process: table count, bottle cavities, tools, hall machines. Plants can propose FAD; they cannot invent your process.

Who is the seller?

The manufacturing plant. This desk issues the English duty sheet.

How to specify an air compressor: Voltage and frequency matter as much as bar. Typical first reply: 1–2 working days after the plant confirms it can hold the duty.
