Shanghai screw compressor works — Shanghai United

United (SUNC) in Jiading Nanxiang is a Hitachi-linked air-end OEM. UD-VPM oil-injected, OSD oil-free screw and the oil-free centrifugal line are three commercial objects. Own air-ends are the works claim on the public about page.

Shanghai United rows published here: UD-VPM PM VSD oil-injected screw; OSD oil-free VSD screw; Oil-free centrifugal compressors. Those names come from official product pages. Nameplate kW, bar(g) and FAD are confirmed on the RFQ — they are not typed in from a brochure photo.

Shanghai United in Shanghai is a centrifugal conversation (flow, pressure ratio, driver). A catalogue 22 kW oil-injected screw is the wrong packing list. Public rows: UD-VPM PM VSD oil-injected screw; OSD oil-free VSD screw; Oil-free centrifugal compressors.

Food / pharma air for Shanghai United: ISO 8573-1 class on the paper, not a brochure adjective. Dryer and sterile-air extras stay on the RFQ. Named works: Shanghai. Duty-sheet prompts used on this desk: ISO 8573-1 class at package outlet or after treatment; Dryer and sterile / sterile-housing filter; Washdown, filling line or clean-utility duty.

Do not treat “compressor, China” as a Shanghai United RFQ. Architecture (screw compressor) and the Shanghai works belong on the first line.

A buyer comparing Chinese screw compressor factories should treat Shanghai United as one works in the Shanghai cluster, not a warehouse brand. FOB port and inspection window are named on the quotation.
