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 PK3N250B4E-YZ5 is a 250mm EC Backward Curved Centrifugal Fan with Support Bracket designed specifically for industrial air handling systems. Dust, wood chips, and particle matter are continuously produced by production lines in industries such as wood processing, furniture manufacturing, chemicals, metallurgy, and food processing. These items must be collected and transported to a central dust collector via a system of central dust collection ducts. The high-efficiency EC motor in this fan uses between 30% and 50% less energy than traditional AC motors under all operating conditions. The EC motor generates less heat during operation in applications such as high-temperature exhaust systems, which stops extra heat from being released into the airflow and further heating the airstream.
Industrial ventilation, heating, refrigeration, battery environmental management, new energy production lines, high-end automation equipment, medical devices, and power electronics are just a few of the high-precision industrial sectors that PBM supports. Superior EC/DC fans and sophisticated airflow solutions are the company's areas of expertise. We support dust collection and air treatment systems. PBM offers a variety of tailored services to meet the different needs of industrial equipment manufacturers.
