Six Reasons Plant Engineers Choose Us
Not the cheapest, not the largest — but the partner that engineers and EPC buyers come back to, project after project.
Engineering-Driven Manufacture
We forge, cast, machine, balance and assemble in-house — full control over quality from raw material to finished fan.
Engineering Support, Not Just Sales
Send your spec and get a sized fan, performance curve and quotation from a chief engineer — not a price list from a salesperson.
ISO 9001 Quality, Documented
Material certificates, dimensional reports, balance records and run-test data accompany every shipment.
Process-Specific Engineering
50 °C ambient, 380/415/440 V, high dust, corrosive gas — fans engineered to your exact site conditions.
Spare Parts on the Same Drawing
Original drawings stay on file, so replacement impellers and wear parts are form-fit years later.
Transparent Pricing & Terms
EXW / FOB / CIF · T/T 30/70 or L/C · clear lead times — no hidden costs, no surprises.
How It Works
From RFQ to Running Plant
A clear, four-step path from your first enquiry to a commissioned fan — with engineering support at every stage.
Send Spec
Share flow, pressure, gas temperature and application — or just your nameplate / datasheet.
Sized Quote
Get a model, performance curve, price and lead time — sized and signed by a chief engineer.
Production
We forge, cast, machine, dynamically balance to G6.3 and run-test before shipment.
Ship & Support
FOB Qingdao / Shanghai with full documentation, plus on-site or remote commissioning support.
