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-RZ0 220mm IP55 EC-DC Backward Curved Centrifugal Fan is designed for renewable energy equipment cooling including photovoltaic inverter cabinets, energy storage system cooling, and EV charging pile cooling modules, as well as industrial ventilation and dust collection systems such as factory exhaust, dust collection systems, and drying equipment air supply.
With high static pressure output, this backward curved centrifugal fan easily overcomes resistance from HEPA filters, dense coil arrays, and long-distance ductwork, maintaining stable airflow in AHU, FFU, and cleanroom systems. The fan supports 0–10V DC / PWM dual-mode stepless speed control input.
With over 15 years of expertise in DC/EC motor and fan technologies, PBM provides complete engineering support and multi-dimensional customization services.
Choose the PB3N220B48-RZ0 for a high static pressure, low noise, IP55 EC-DC backward curved centrifugal fan.
