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.
400mm DC Backward Curved centrifugal fan made especially for AHUs in Telecom and Cloud Server Data Center is the PB3N400B48M. The motor's electromotive force is synced with the stator voltage thanks to a high-efficiency DC brushless motor that combines asynchronous start and permanent magnet synchronous motor technology, resulting in a highly integrated intelligent motor system. Its lightweight and compact design saves a large amount of installation space within the AHU unit enclosure by combining the high efficiency and energy-saving capabilities of DC motors with the ease of direct grid connection of AC motors.
We provide OEM customization services. PBM offers airflow solutions for your data center air handling systems in addition to manufacturing fans. PBM enables data center owners, IDC operators, and HVAC engineering clients achieve reduced PUE, quieter operation, more dependability, and more affordable contemporary data center HVAC infrastructure with its excellent DC backward centrifugal fan technology.
