XINLEI Compress Co., Ltd.
About
Xinlei Compressor Co., Ltd. is a Chinese manufacturer headquartered in Zhejiang Province that produces over 800,000 units of energy-saving air power equipment annually, sold across more than 110 countries. The company's cumulative equipment runtime exceeds 210 million hours with reported energy savings exceeding 149 billion kWh. Xinlei's core technology centers on magnetic levitation and air suspension bearing systems adapted from aircraft turbine engine design, applied across a comprehensive product range serving both general industry and wastewater treatment. For sewage treatment aeration, Xinlei offers oil-free screw blowers, magnetic suspension centrifugal blowers, air suspension centrifugal blowers, permanent magnet variable frequency centrifugal blowers, and high-speed aerators — all designed for continuous-duty oxygen delivery in activated sludge basins. The company also manufactures magnetic levitation centrifugal compressors and vacuum pumps for industrial process applications. Beyond aeration, Xinlei produces a full line of screw air compressors: the SE series in single-stage and two-stage oil-cooled configurations, the JF and AP series in air-cooled versions including all-in-one packaged units combining compressor, dryer, and filtration, and SE and JF water-cooled models for high-duty-cycle environments. Permanent magnet variable frequency screw compressors provide part-load energy optimization. Additional product lines include XLSC screw heat pump units for HVAC applications, magnetic levitation centrifugal chillers, piston compressors, and refrigeration compressors. Xinlei operates both OBM and OEM business channels, serving sewage treatment, petrochemical, cement, mining, food, and textile industries.
