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 PB3N310B2E-MZ0 310mm IP55 EC-AC Backward Curved Centrifugal Fan is specifically engineered for air handling units (AHU) and modular air conditioning systems including fresh air systems, central air conditioning fan coils, and industrial ventilation units — delivering high-efficiency AC-driven performance in demanding industrial ventilation scenarios requiring high static pressure with waterproof and dustproof protection.
Powered by EC motor technology, this backward curved centrifugal fan delivers significant energy savings compared to traditional AC induction motors across all operating conditions. The motor generates minimal waste heat emissions into the circulating airstream, imposing no additional thermal load on temperature- and humidity-controlled cleanroom HVAC systems.
PBM backward curved centrifugal fans are widely used across industrial and commercial ventilation, HVAC systems, cleanrooms, and other critical environments.
Choose the PB3N310B2E-MZ0 for a high static pressure, low noise, IP55 EC-AC backward curved centrifugal fan for your most demanding AHU and HVAC applications.
