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.
160mm EC forward curved centrifugal fan from PBM is made especially for medium-sized commercial fresh air systems and air handling equipment. With an air volume of 670 m³/h, static pressure of 378 Pa, speed of 2160 RPM, power of 177 W, and noise level of under 70 dB (A), it employs a 230V EC motor. By successfully overcoming the resistance of HEPA filters and branch ducts, the forward-curved impeller design maintains an adequate air volume even under medium to high static pressure, guaranteeing that clean air is distributed uniformly throughout every area. The 670 m³/h air volume is appropriate for stores or offices of 100–150 square meters, and the 378 Pa static pressure satisfies the air supply needs of duct systems up to 20 meters long. Significant energy savings can be achieved by using the EC motor with a CO₂ sensor for on-demand operation and supporting 0-10V/PWM stepless speed control. Because of its low noise level, it may be used in commercial and office settings where quiet operation is necessary. Ceiling installation is made possible by IP44 protection. It is the perfect power source for compact fresh air exchangers, air conditioners, and purification equipment because of its 50,000-hour lifespan, which guarantees long-term, reliable operation in commercial venues.
