Datasheet
Product overview
United UD-VPM single-stage permanent-magnet VSD screw compressors from Shanghai United / SUNC Compressor (Hitachi JV)
United's UD-VPM page identifies a single-stage permanent-magnet variable-speed screw family with published working ranges of 5.5–55 kW, 7–10 bar and 0.9–10.6 m³/min. These are separate family ranges; they do not establish one model's simultaneous rating or a pressure-matched delivery point. Obtain the complete model sheet with air-delivery reference conditions and the test basis.
The manufacturer describes an oil-injected air end, an integrated motor/air-end drive arrangement, variable-speed vector control and oil/air separation. It publishes a motor enclosure reference of IP65 for this range; confirm the offered model's actual motor and drive configuration. Do not transfer the enclosure rating to the complete machine or treat oil separation as oil-free construction.
Specify minimum, normal and peak air demand, required outlet and point-of-use pressures, operating schedule, power supply and ambient/ventilation conditions. Ask for delivery and total package input at the selected pressures, permitted speed/demand range and part-load behaviour. Coordinate dryers, filters and the distribution pressure-drop allowance separately. The photograph is the corresponding official UD-VPM family image, rather than a substitute compressor or a dimensional drawing.

Specification pages
Specifying a Rotary screw duty
| Duty | Write on the RFQ |
|---|---|
| Compressor for a textile factory | Jet looms and spinning do not share a pressure. Write the machine OEM’s bar(g) and the hall FAD, then 50 Hz voltage for most Asian mills. |
| Compressor for CNC machines | Machine tools need dry, stable 7–8 bar air. Size from the cell, not from a round kW number a vendor likes to sell. |
| How to specify an air compressor | If the RFQ only says “compressor, China”, a plant cannot price it. Start with architecture, then the duty point, then the papers. |
