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 EC reverse centrifugal fan PB3N400B2EX is made especially for air handling units (AC units) and central air conditioning units (AHUs). It has a very efficient EC motor that is powered directly by 230V AC mains. Under all operating circumstances, it offers notable energy savings of 30% to 50% when compared to conventional AC asynchronous motors with the same specifications. The motor itself creates extremely little heat, resulting in minimum waste heat discharged into the circulating air, therefore not increasing the internal thermal load of the AHU and keeping exact control of the supply air temperature.
PMB specializes in the development and production of superior EC/DC fans and intelligent airflow systems. To satisfy the various demands of manufacturers of AHU equipment and central air conditioning units, PBM provides a range of specialized services.
