FOCUS ON EC FAN ONLY
PBM FOCUS ON EC FAN ONLY. Certificate: CE,UL,ROHS; Supply Ability: 100,000 pcs per year; MOQ: 1~100 pcs based on EXW price; 100 pcs above based on FOB price.
The PB3N220B48-TZ0 220mm IP55 DC Backward Curved Centrifugal Fan is designed for cleanroom systems and FFU fan filter units in semiconductor cleanrooms, pharmaceutical workshops, and biological laboratories — overcoming HEPA filter resistance and maintaining stable cleanroom differential pressure in ultra-high static pressure industrial ventilation applications.
Rated at 48V DC and powered by advanced brushless DC (BLDC) / EC motor technology, this backward curved centrifugal fan delivers an industry-leading 1165 m³/h (685.6 CFM) of airflow and 950 Pa (3.80 inH2O) of ultra-high static pressure at 3,500 RPM. The 950 Pa ultra-high static pressure easily overcomes cumulative resistance from HEPA filters, dense coil arrays, and long-distance ductwork, ensuring stable airflow in AHU, FFU, and cleanroom systems.
Choose the PB3N220B48-TZ0 for a high static pressure, low noise, IP55 EC-DC backward curved centrifugal fan for your most demanding cleanroom and FFU applications.
