Duty sheet
Zhongshan
Aipuer in Zhongshan Xiaolan publishes two-stage and PM VSD oil-injected screw. It is a PRD factory-air OEM, not a process-gas API shop.
Aipuer rows published here: Two-stage screw; PM VSD screw. 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.
If the RFQ only says “screw compressor, China”, Aipuer in Zhongshan cannot price it. Start with the published architecture — Two-stage screw; PM VSD screw — then bar(g) and FAD.
General factory air for Aipuer: kW or FAD, bar(g), 50/60 Hz and voltage, plus whether the package is oil-injected or oil-free. Named works: Zhongshan. Duty-sheet prompts used on this desk: Working pressure in bar(g); Required FAD at that pressure; Motor kW or site limit.
Do not treat “compressor, China” as a Aipuer RFQ. Architecture (screw compressor) and the Zhongshan works belong on the first line.
A buyer comparing Chinese screw compressor factories should treat Aipuer as one works in the Zhongshan cluster, not a warehouse brand. FOB port and inspection window are named on the quotation.
