Fusheng SWT oil-free screw compressors — Fusheng

Datasheet

Product overview

Power: 55–400 kW, family envelope · Pressure: 7.5–10 bar, model-dependent · Flow: 6.9–66.8 m³/min, family envelope

Fusheng's mainland SWT page describes an oil-free screw compression process with gear drive and shaft sealing. Its catalog lists family bounds of 55–400 kW, 0.75–1.0 MPa working pressure and 6.9–66.8 m³/min delivery. Those limits span the family and are not a single machine's simultaneous rating. The original family illustration carries SWTV250WIII identification; no pressure, flow or motor rating is assigned to it without a corresponding model row.

The manufacturer describes drawer-type coolers and monitoring of compressed-air temperature and humidity. Ask for the actual cooling arrangement, service withdrawal space, inlet conditions and selected-model performance. A compression air path without lubricating oil is separate from gearbox/bearing lubrication and from downstream drying.

The product page states ISO8573-1 Class 0. Where this is a process requirement, obtain the exact offered model's certificate and test scope, conditions and air-quality measurement boundary. Define pressure dew point and particles independently, followed by receiver, dryer, filtration and distribution acceptance. Do not interpret oil-free as sterile or already dry air.

Submit duty pressure, normal/peak/minimum demand, operating hours, process-air quality, electrical supply and site/cooling conditions. Agree capacity reference, package input and control range, installation drawings, treatment scope, serial/model-linked test records, destination documentation and commissioning/service responsibilities. The quotation should identify the legal seller and assembly/test site rather than assuming every group package has the same origin.
