Will you quote a screw for aeration?
Not as a default. If the process engineer asked for 50–80 kPa, that is a blower RFQ.
Application
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.
What belongs on the RFQ
Numbers a plant can quote
Maglev and high-speed centrifugal blowers from Chinese plants serve aeration. Do not send that duty to an oil-injected 8 bar screw list. Discharge pressure in kPa and air flow in Nm³/min belong on the sheet.
If the site needs instrument air, use a screw duty instead. This page matches published centrifugal / process series; the RFQ must still name blower vs compressor.
- Aeration blower vs 7–8 bar instrument air
- Discharge pressure (kPa or bar)
- Flow and turndown
- Gas (usually air) and ambient
- Motor kW and voltage
- 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
Compressor for wastewater treatment: Voltage and frequency matter as much as bar. Typical first reply: 1–2 working days after the plant confirms it can hold the duty.
