Is water-lubricated the same as dry screw?
No. Water-lubricated oil-free screw is a distinct architecture on Sunsource’s public list. Dry screw is a different OEM conversation.

Wenling
Oil-free specialist, four public families
Sunsource (Zhejiang Shengyuan Air Compressor) is a Zeguo, Wenling oil-free specialist. The desk lists water-lubricated oil-free screw, silent oil-free compressors, laboratory / research compressors and EV onboard oil-free compressors from the factory’s public list pages — each URL is a different commercial object.
Water-lubricated screw is not a silent piston box. Laboratory machines care about duty cycle, noise and often oil-free at small flows. EV onboard is a vehicle component RFQ (voltage, envelope, vibration), not a factory-air packing list. Treating them as one “oil-free compressor” block is how Google and buyers both see a template.
CE is listed from the public-page check. The plant remains the seller.

Buyer notes
Water-lubricated vs silent piston
Can this factory quote a diesel portable 18 bar for mining?
That is not the published series. This page is oil-free specialist lines from Zeguo.
Medical air — do you print a pharmacopoeia certificate?
Only if the works sends the paper. This desk does not invent a medical certificate.
