Xinda Ningbo publishes named screw series: XG two-stage, WG water-lubricated oil-free and SD portable. Those are not one packing list. Own air-ends are the works claim. Emails on the page are personal QQ — CRM stays empty.
Ningbo Xinda Screw Compressor rows published here: XG(P)T two-stage screw; WG(P)S water-lubricated oil-free screw; SD(C)Y portable 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.
A coalescing filter on an oil-injected machine does not make it a Ningbo Xinda Screw Compressor oil-free quote. Ningbo public oil-free / clean-air rows: XG(P)T two-stage screw; WG(P)S water-lubricated oil-free screw; SD(C)Y portable screw. ISO class stays on the paper, not in the headline.
Food / pharma air for Ningbo Xinda Screw Compressor: ISO 8573-1 class on the paper, not a brochure adjective. Dryer and sterile-air extras stay on the RFQ. Named works: Ningbo. 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 Ningbo Xinda Screw Compressor RFQ. Architecture (screw compressor) and the Ningbo works belong on the first line.
Papers on this Ningbo Xinda Screw Compressor file are only marks that survive a public-page check. Missing ISO class, PED or ASME is left missing. Packing, Incoterm and lead time come from the Ningbo works — Ningbo Xinda Screw Compressor remains the seller.
