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

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.
