Shandong Huadong Blower Co. Ltd
About
Shandong Huadong Blower Co., Ltd. is a Chinese manufacturer based in Jinan City, Shandong Province, with over 20 years of experience producing Roots-type blowers, vacuum pumps, and compressors for industrial and environmental applications. Recognized by China's Ministry of Industry and Information Technology as an energy-saving equipment manufacturer, the company has developed both air bearing and magnetic levitation turbo blower core technologies. The HDSR series of three-lobe Roots blowers covers capacities from 0.45 to 198.1 cubic meters per minute at pressures up to 98 kPa, serving wastewater treatment, pneumatic conveying, and general industrial aeration. The HDSR-MJ variant delivers the same performance envelope in a compact footprint for space-constrained installations. The HDLH series targets aquaculture aeration with capacities from 0.15 to 31.84 m3/min, while the HG series offers high-rotary-speed, air-cooled operation from 0.5 to 157.2 m3/min. The HDR two-lobe design provides large-capacity air delivery from 4.04 to 452.4 m3/min for heavy industrial duty. The HDSR-V Roots vacuum pump handles negative-pressure applications from -9.8 to -79.9 kPa. Huadong also manufactures sealed gas and biogas blowers for landfill gas recovery and agricultural biogas, MVR mechanical vapor recompression steam compressors in SS304, SS316L, and SS2205 stainless steel for zero-discharge evaporation, and dedicated aquaculture aeration blowers. The company holds ISO and CE certifications, cooperates with Fortune 500 partners, and is expanding internationally through China's Belt and Road initiative.
