Import 5.5kw Mini Screw Air Compressor — Buy in Bulk from Supplier in China

The 5.5kW Mini Screw Air Compressor from Shandong Hanchau International Trading Co., Ltd. is a rotary screw compressor rated at 5.5 kilowatts, designed for continuous-duty compressed air supply in industrial settings. The unit employs a positive-displacement screw mechanism with intermeshing rotors, delivering consistent airflow without the pulsation common to reciprocating designs. Its compact footprint suits workshops and manufacturing floors where space is constrained, while the 5.5kW motor rating positions it for light to medium pneumatic tool loads and small-scale automation. The supplier sources this unit from Linyi City, Shandong Province, a region with established machinery manufacturing infrastructure.

The airend typically comprises precision-machined helical rotors housed in a cast-iron casing, with bearings rated for continuous operation. Standard industry practice for this power class includes an air-cooled oil-injected system, where compressor oil serves dual duty for sealing and heat removal, with typical discharge temperatures of 80 to 100 degrees Celsius after the airend. Oil separation is normally achieved through a combination of mechanical impingement and coalescing filtration, with residual oil content typically below 3 parts per million at full load. The drive train may be direct-coupled or belt-driven depending on the specific variant; buyers should confirm the configuration with the supplier. Noise attenuation is commonly addressed through acoustic enclosures or lined sheet-metal panels, with typical sound pressure levels in the 65 to 75 decibel range at one metre for enclosed screw compressors in this kilowatt class.

This compressor suits workshops running pneumatic drills, grinders, spray guns and small automated assembly equipment. Typical buyers include automotive repair facilities, metal fabrication shops, woodworking operations and packaging lines requiring 400 to 700 litres per minute of free air delivery at 7 to 8 bar working pressure. Shandong Hanchau International Trading Co., Ltd. lists flexible minimum order quantities and offers FOB and CIF shipping terms, though exact figures are not stated and should be confirmed directly. The supplier holds a harbor-tier trust rating with no recorded response data, so buyers should establish communication channels and verify lead times, warranty coverage and spare parts availability before committing.

Shandong Hanchau International Trading Co., Ltd. is based in Linyi City, Shandong Province, with registered address at Linyi 276000. The company operates as an imported-tier supplier on the platform, indicating it was onboarded through external data sources rather than direct verification. Its trust tier is classified as harbor, which represents a baseline verification level. The response rate is recorded at 0.00 percent with zero average response hours, meaning no response data is available through the platform. Buyers should therefore initiate direct contact via the supplier's listed channels to assess responsiveness.

The company's profile does not disclose establishment year, registered capital, employee count, factory ownership, revenue figures, named clients, or specific quality certifications. No ISO certificates or other accreditations are confirmed in the available data. The supplier's primary category is air compressor trading, with this 5.5kW mini screw unit representing its listed offering. Given the limited verification signals, due diligence should include a request for business licence, factory audit reports or third-party inspection certificates before placing a substantial order.
