PBM Motor and Fan (Suzhou) Co., Ltd. is one of the most reliable manufacturers and suppliers of 310mm waterproof ip55 ec-ac backward curved centrifugal fan pb3n310b4e-yz5 in China. With abundant experience, we are committed to providing high quality customized products with competitive price. If you're going to buy bulk premium 310mm waterproof ip55 ec-ac backward curved centrifugal fan pb3n310b4e-yz5, welcome to get pricelist from our factory.
Rated at 380V AC (operating range 304–456V AC) with 50/60 Hz compatibility, and powered by EC motor (electronically commutated brushless motor) technology, this backward curved centrifugal fan delivers an industry-leading 4500 m³/h (2648.25 CFM) of airflow and an industry-top 1600 Pa (6.40 inH2O) of static pressure at 3,000 RPM. The 1600 Pa ultra-high static pressure easily overcomes cumulative resistance from HEPA filters, dense coil arrays, and long-distance ductwork, ensuring stable airflow in central dust collection systems, AHU, and cleanroom systems.
Choose the PB3N310B4E-YZ5 for a high static pressure, low noise, IP55 EC-AC backward curved centrifugal fan for your most demanding large-scale ventilation applications.
