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.
220mm EC Centrifugal Fan with Bracket from PBM is made especially for quiet commercial ventilation systems and upscale office buildings. It has an air volume of 1000 m³/h, a 230V EC motor running at 3100 RPM, and a noise level of just 69 dB (A). Without the need for intricate enclosures, the bracket design enables direct installation into duct systems or ventilation units. It may be installed within office ceilings without interfering with staff work or meetings because of its extremely low noise level of 69 dB(A). The 1000 m³/h air volume satisfies the ventilation requirements of highly populated areas and is appropriate for open-plan workplaces or meeting rooms with 150–200 square feet. Significant energy savings can be achieved by using the EC motor with a CO₂ sensor for on-demand air delivery and supporting 0-10V/PWM stepless speed control. A 50,000-hour lifespan guarantees long-term reliable operation in commercial settings, and IP55 protection adapts to dusty ceiling situations, making it the perfect power source for complete heat exchangers and silent ventilation systems.
