Shenjiang piston and portable miniature compressors, Changzhou

Changzhou Shenjiang Compressor (Changzhou Shenjiang Compressor Co., Ltd.) sits in Caoqiao, Wujin. The official site is a short factory page, not a slogan wall. It states that the company was founded in 1996 and is one of Jiangsu’s specialised makers of portable miniature air compressors. In 2005 it invested a 2,000 m² foundry and a 1,500 m² machining shop for compressors and parts. That is the useful identity for a buyer: a piston and portable works with its own iron, not a trading label pasted on a Wenling carton.

The homepage tiles that survive a public-page check are industrial piston frames, a portable miniature line, plus a rotary-screw tile, a four-in-one screw package and a refrigerated dryer. This English desk publishes only two series from that file: SHENJIANG-PISTON and SHENJIANG-PORTABLE. The screw and dryer families are real objects on the factory site. They are not minted as extra SKUs here. If you need a four-in-one package, write that duty in prose and let Shenjiang name the frame.

Three piston tiles print frame names a buyer can actually read: V0.67-8, V0.2-10 and V1.05-12. Those strings are homepage labels, not a complete nameplate. Displacement, pressure and motor power stay confirm-on-RFQ unless a later official datasheet is attached to the quote. Do not treat a photograph of a tank as a kW band.

Portable miniature air is a different commercial object from a workshop piston set on a receiver. Wheels, tank volume, single-phase versus three-phase and whether the machine lives in a service van all change the packing list. An indoor piston set needs voltage, frequency and the duty cycle. Mixing both on one model line is how Caoqiao sends a clarifying question instead of a price.

The about block says products meet national standards, that the works is a Changzhou metrology-qualified enterprise, that it holds ISO 9001-2000, and that it holds a compressor-industry production licence. This listing will not upgrade that 2000-edition quality certificate into ISO 9001:2015, and it will not invent ISO 8573-1 Class 0, CE or ASME. If you need the current scan, the RFQ asks Shenjiang for the scan.

Contact lines on the same homepage print a Caoqiao, Wujin address and landline numbers. They do not print an export Incoterm. A European buyer who wants FOB Shanghai still has to write the port, the voltage and whether the crate is a wheeled miniature or a receiver-mounted piston. Use the Caoqiao landline the quotation names.

Changzhou is a piston-and-accessories cluster as much as a screw cluster. Shenjiang’s own about block leans on portable miniature air and on the 2005 foundry investment. That is why a 200 kW factory-screw RFQ is the wrong sheet even though a screw tile sits on the homepage. If the buyer later needs the screw or the four-in-one package, the works can name the frame. This catalogue will not invent one.

The seller is Shenjiang. CompressorB2B does not buy a Caoqiao piston and relabel it. Put architecture, pressure and the works on the sheet. Quotes, Incoterms and the commodity code on the packing list come from Changzhou.
