Duty, not brochure
Pressure, FAD, voltage, oil-free class and destination port. The desk matches plants that can actually build it.
Specification desk · EN
Specify the compressor. Then RFQ the plants that can build it.
Not another China supplier list. A technically correct duty sheet — kW, bar, FAD, voltage, ISO class — sent to Chinese factories that can actually hold it.
The airend
Duty first. Supplier list second.
We do not help you browse another China compressor directory. We help you specify kW, bar, FAD, voltage and ISO class, then send the same English RFQ to Chinese plants that can actually build it.
Duty catalog
Machines on the desk
Engineers compare kW, bar and FAD — not storefront tiles. Series are listed from each plant’s published data. Empty cells stay confirm-on-RFQ. The plant remains the seller.

Specification pages
Buyer-intent duties, not a supplier list
75 kW 8 bar, PET 40 bar, Class 0 — pages built for how engineers search. Each one RFQs matching listed plants.
| Duty | Write on the RFQ | |
|---|---|---|
| 75 kW 8 bar rotary screw compressor | 75 kW at 8 bar(g) is a common plant-air point. FAD is not a brochure range — it is the flow at that pressure, after the cooler, for the voltage you actually run. | Open |
| 110 kW 10 bar rotary screw compressor | 10 bar(g) is not 8 bar with a different sticker. FAD falls as pressure rises. Write 110 kW and 10 bar together, then the flow you need at that point. | Open |
| 40 bar PET compressor | PET blowing at 40 bar(g) is a high-pressure oil-free duty. Cavities, bottle volume and recovery pressure size the skid — not the word “PET compressor”. | Open |
| Class 0 oil-free compressor | Class 0 means a stated test method at a stated point in the air system. An oil-free airend without a paper is not Class 0 on this desk. | Open |
| Compressor for laser cutting | Choose the air system from the laser maker's gas specification. The compressor motor rating and laser power do not, by themselves, determine the required pressure, flow or air quality. Identify whether the supply is for cutting assist gas, machine services or both before requesting a package. | Open |
| 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. | Open |
Explore Chinese compressor manufacturers by specialty, then open each plant profile to review its product range and request a quote.

Why this desk
Specify the compressor. Then RFQ the plants that can build it.
Overseas buyers do not need another supplier directory. They need a technically correct duty sheet — and the same sheet sent to Chinese factories that can actually hold the pressure.
CompressorB2B (Compressor B2B) is the industrial compressor specification and RFQ platform at compressorb2b.com. Compare product information in English and send one duty sheet to the plants suited to your application. The manufacturing plant provides the quote.
A1
Factory-direct
No relabelled trader stock. The quote comes from the works that machines the airend or packages the skid.
A2
English spec sheets
kW, bar, FAD, voltage, ISO class and packing — written for a buyer file, prepared from the plant’s source data.
A3
Technical documents
Ask for the current datasheet and application-specific certificates with your RFQ.
A4
One RFQ, several plants
Shortlist machines across clusters. We issue the same duty sheet so quotes are comparable.
Export desk
Terms before the PO
FOB Ningbo / Shanghai / Shekou
Standard for screw and piston packages. Plant handles export packing and customs; you nominate the forwarder.
CIF named port
Used when the buyer wants a landed-cost number. Insurance and ocean freight stated as a separate line.
Packing & HS 8414
Plywood cases, moisture barrier, lifting marks. Commodity code and wood treatment called out on the packing list.
Inspection
Factory trial run, third-party inspection on request, and documents scanned before the vessel cut-off.
FAQ
Buyer questions
What goes on the duty sheet, who sells the machine, and which factories appear on this English desk.
What specification should an RFQ include?
Working pressure in bar(g), required FAD at that pressure, motor kW or site limit, ISO 8573-1 class if oil-free, 50/60 Hz and voltage, quantity, destination and FOB or CIF.
Who is the seller?
The manufacturing plant. CompressorB2B is the English specification desk and RFQ router — not a trading company.
Do you sell as a trader?
No. The plant remains the seller. CompressorB2B is the English specification desk and RFQ router.
What HS code applies?
Most air compressors ship under HS 8414. The packing list states the commodity code and wood treatment.
Desk notes
Specify before you buy
ISO class, PET pressure, FOB packing — written for a buyer file, not a brochure.
FOB Ningbo and HS 8414 packing
Terms before the PO: plywood cases, moisture barrier, lifting marks and the commodity code on the packing list. The plant remains the seller.
PET blowing: 30–40 bar packages
Bottle blowing is a high-pressure oil-free duty. Cavities, recovery and booster staging belong on the RFQ.
ISO 8573-1 Class 0 for food and pharma air
Class 0 is a plant claim against a stated test method, not a sticker. Put the class, dryer and sterile filter on the duty sheet.
How to write a factory-direct compressor RFQ
Send bar(g), FAD, kW, ISO 8573-1 class, voltage and Incoterm. The desk routes the duty sheet to the works that can build it.
RFQ desk
Send the duty sheet
A plant engineer can answer this form. If you already shortlisted models, they are copied in. If not, describe the process and we route it.
- → Work email only. Quotes go to the company, not a public inbox.
- → Voltage and frequency matter as much as bar. State both.
- → Typical first reply: 1–2 working days after the plant confirms capacity.
Chinese plants: send the product list and certificates. We handle the English specification pages and the buyer RFQ. Onboarding lives on the factory-join page.
