Specification pages
Specify the duty, then RFQ the plants that can build it
Browse compressor duties by power, pressure and application. Open a specification page to see matching products and plants.
We do not help you browse another China compressor list. Each row is a duty you can put on a PO. Open it, check the RFQ points, send the same English sheet to matching plants.
Parameter duties
| Duty | What to write | |
|---|---|---|
| 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 |
| 22 kW VSD screw compressor | 22 kW VSD is a flow band, not a single nameplate FAD. The plant needs min/max flow at the working pressure, or it will quote a fixed-speed machine with an inverter sticker. | Open |
| 13 bar rotary screw compressor | 13 bar(g) is a laser and textile pressure, not a general 8 bar plant. Write FAD at 13 bar and the kW the site can feed. | Open |
| 30 bar oil-free compressor | Specify whether 30 bar is gauge or absolute pressure, where it is required and how much air must be supplied at that point. A 30 bar working duty does not, by itself, identify a compressor architecture, motor size or air-quality class. | 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 |
| 50 Hz 380 V screw compressor | Chinese plants build 50 Hz 380 V packages every day. They cannot retag a 60 Hz 460 V nameplate in the quotation without a motor change. Write the supply first. | Open |
Technology
| Duty | What to write | |
|---|---|---|
| Rotary screw compressor manufacturers in China | China already has more screw-compressor storefronts than a buyer can audit. This desk lists manufacturing plants against a duty sheet — kW, bar(g), FAD — and routes one English RFQ. | Open |
| 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. | Open |
| Centrifugal compressor manufacturers in China | Centrifugal machines are duty-built. A 250 kW “centrifugal compressor China” RFQ without gas, suction and discharge pressure cannot be quoted. | Open |
| Piston compressor manufacturers in China | 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. | Open |
| Refrigeration screw compressor manufacturers in China | A refrigeration screw compressor is selected for a refrigerant and operating conditions. Start with required cooling capacity, evaporating and condensing temperatures, electrical supply and the system arrangement. An air-compressor pressure rating or a motor nameplate alone cannot define this duty. | Open |
| Process gas compressor manufacturers in China | Process gas is not plant air. Molecular weight, suction pressure, discharge pressure and flow size the machine. A kW from an air catalogue is unused. | Open |
Applications
| Duty | What to write | |
|---|---|---|
| Compressor for PET bottle blowing | Bottle blowing is a high-pressure oil-free process. The blower OEM’s pressure and the cavity count size the compressor, not the word PET. | 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 |
| Compressor for a food factory | Food air is a validation file. Class, test point and treatment matter as much as kW. A general 8 bar screw without papers is not a food quote. | Open |
| Compressor for a pharmaceutical plant | Pharma procurement is a document pack: IQ/OQ support, material certs, residual oil. The machine is the easy part if the RFQ lists the papers. | Open |
| Compressor for a textile factory | Jet looms and spinning do not share a pressure. Write the machine OEM’s bar(g) and the hall FAD, then 50 Hz voltage for most Asian mills. | Open |
| Compressor for mining | Site air at altitude is not a 7 bar catalogue FAD. Diesel vs electric, hose length and ambient change the machine. | Open |
| Compressor for CNC machines | Machine tools need dry, stable 7–8 bar air. Size from the cell, not from a round kW number a vendor likes to sell. | Open |
| Compressor for wastewater treatment | Most aeration trains want low-pressure blowers. If this RFQ is actually 7–8 bar plant air for valves and instruments, say so — it is a different machine from a maglev blower. | Open |
Procurement
| Duty | What to write | |
|---|---|---|
| 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 |
| Compressor RFQ — one English duty sheet | The product is not a directory row. The product is a duty sheet a plant can quote against — and the same sheet sent to more than one works. | Open |
| Compressor procurement checklist | A $1,500 workshop piston and a $100,000 oil-free skid do not share a checklist. This page is for industrial packages bought from Chinese plants on an English duty sheet. | Open |
| FOB compressor from China | FOB is the default industrial quote: the plant packs and clears export, you nominate the forwarder. CIF is a landed-cost option with freight as a separate line. | Open |
Not on a spec page: If the duty is not listed, write it. Voltage and frequency matter as much as bar.
