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 PB3N190B2E-RZ2 190mm IP55 EC-AC Backward Curved Centrifugal Fan is designed for fresh air systems and energy recovery ventilators (ERV) including wall-mounted and ceiling-mounted units, serving residential and commercial ventilation applications requiring medium-to-high static pressure with waterproof and dustproof protection.
Powered by EC motor (electronically commutated brushless motor) technology, this backward curved centrifugal fan delivers 30%–50% energy savings compared to traditional AC induction motors. Compared to RZ0/RZ1 versions (450–540 m³/h, 450–530 Pa), the RZ2 version significantly enhances performance to 800 m³/h airflow and 790 Pa static pressure, making it ideal for commercial purification equipment and industrial exhaust systems.
With over 15 years of expertise in EC/AC motor and fan technologies, PBM offers full customization and complete engineering support from sample validation to mass production for commercial air purifiers, fresh air systems, range hoods, and industrial exhaust equipment.
Choose the PB3N190B2E-RZ2 for a high static pressure, low noise, IP55 EC-AC backward curved centrifugal fan.
