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 PB3N220B2E-RZ0 IP55 EC-AC Backward Curved Centrifugal Fan is a high-efficiency AC-driven cooling solution specifically engineered for demanding ventilation scenarios requiring waterproof and dustproof protection, including electrical control cabinet cooling and outdoor enclosure cooling such as telecom base station cabinets, outdoor electrical boxes, and photovoltaic inverter cabinets, as well as industrial automation equipment cooling including variable frequency drive (VFD) cooling, servo drive cooling, and PLC control cabinet cooling. Powered by EC motor (electronically commutated brushless motor) technology, this backward curved centrifugal fan combines the convenience of direct AC mains connection with the high-efficiency control characteristics of a DC motor. Compared to traditional AC induction motors, the EC motor delivers 30%–50% energy savings across all operating conditions, significantly reducing long-term energy costs for fresh air systems and industrial ventilation equipment.
PBM is more than just a fan manufacturer — we are your ventilation and thermal management system solution provider. With an IP55 protection rating ensuring reliable operation in harsh environments, and full OEM customization services available, the PBM technical team provides complete engineering support from sample validation to mass production delivery.
