Parameter duty

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.

What belongs on the RFQ

Same sheet, matching plants

Small VSD screws are often bought for workshops that do not run a flat 22 kW load. If the RFQ only says “22 kW inverter screw”, the plant cannot size the airend turn-down or the dryer.

State working pressure, the lowest and highest FAD you expect, whether the motor is PM or induction, 50/60 Hz, and if the starter and cabinet must be tropicalised. Altitude matters more on a small package than buyers expect.

Matching rows are published oil-injected screw series from listed Chinese plants. PM VSD is a plant claim against a stated motor — we do not print IE4 on a page that the factory did not document.

FAQ

22 kW VSD screw compressor — buyer questions

Is VSD always cheaper to run?

Only if the load actually varies. A flat 22 kW duty can be cheaper as fixed speed. Put the load profile on the sheet.

Do you list a 22 kW SKU?

Only if a published plant series exists. This page is the duty. Missing FAD stays confirm-on-RFQ.

22 kW VSD screw 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.
