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 250mm EC fan PK3N250B2E-MZ0 was created especially for fresh air handling units (MAUs), fan filter units (FFUs), and clean air handling units (AHUs). It offers substantial energy savings of 30% to 50% over conventional AC fans under all operating situations because to its high-efficiency EC motor. During operation, the EC motor produces extremely little heat and releases very little waste heat into the surrounding air. It does not provide extra thermal burden to the AHU interior in cleanroom air conditioning systems with constant temperature and humidity, therefore supply air temperature is precisely controlled.
In addition to supporting modular air handling units, fan filter units, and cleanroom air conditioning systems, PBM specializes in the research and development and production of premium EC/DC fans and intelligent airflow solutions. PBM provides customisation services to meet the various demands of manufacturers of air handling equipment.
