Import 25hp Screw Air Compressor — Buy in wholesale FOB from Supplier in China

The 25hp screw air compressor from Dongguan City Jiubei Compressor Co.,Ltd is a rotary screw type positive displacement compressor delivering continuous compressed air for industrial automation and powered tooling. The 25 horsepower (approximately 18.5 kW) motor drives a pair of meshing helical rotors within an air-end housing, producing oil-flooded compressed air at typical discharge pressures of 0.7 to 1.0 MPa (7 to 10 bar). Screw compressors of this rating typically deliver free air delivery (FAD) in the range of 2.5 to 3.5 cubic metres per minute at 7 bar, though buyers must confirm the exact FAD and specific power (kW per m3/min) with the supplier for this model.

The air-end assembly typically contains high-precision timing gears and coated rotors with tip clearances of 0.03 to 0.10 mm, requiring clean intake air and proper lubricant maintenance for longevity. Separators downstream of the compression chamber reduce oil carryover to less than 3 ppm by mass, with filtered intake systems using paper or synthetic media rated at 5 to 10 micrometres absolute. Cooling is usually air-cooled via a motor-driven fan and aluminium finned heat exchanger, though some variants offer fluid cooling for enclosed installations. The compressor package integrates an aftercooler to reduce discharge air temperature, a moisture separator, and typically a microprocessor-based controller with pressure transducer feedback.

This capacity class serves automotive repair facilities, general machining workshops, packaging lines, textile operations and small manufacturing plants running pneumatic actuators, spray guns, grinders and assembly tools. Buyers should confirm whether the unit is base-mounted, tank-mounted with integrated air receiver, or packaged with a refrigerated air dryer. For import from Dongguan, Guangdong Province, verify the motor efficiency class (IE2, IE3 or IE4), noise emission level in decibels, and whether the control system offers load/unload, variable speed or fixed-speed operation. The supplier's location in Chang'an Town places it within Dongguan's dense manufacturing equipment supply chain.

Dongguan City Jiubei Compressor Co.,Ltd is located in Chang'an Town, Dongguan, Guangdong, China, postal code 523800. The supplier holds harbour trust tier status on the platform, with a response rate of 0.00 and no recorded average response hours. This limited communication trace means buyers should initiate direct contact early to assess responsiveness and English-language capability before relying on platform messaging alone.

The company profile does not disclose founding date, factory size, employee count, annual turnover, export markets served, or specific quality certifications held. No ISO 9001, ISO 14001, CE marking or other compliance documentation is verified in the available data. Chang'an Town is a significant manufacturing hub within Dongguan, but this geographic concentration alone does not indicate production capability or quality systems. Buyers should request a company introduction brochure, factory video tour, and customer reference list for compressors sold to their target market. Due diligence should include verification of the business licence scope to confirm air compressor manufacturing is an authorised activity.
