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.
630mm EC Centrifugal Fan with Bracket is made especially for the cooling and ventilation systems of big generator sets and motors. With an airflow of 18,600 m³/h, static pressure of 900 Pa, speed of 1250 RPM, power of 2700 W, and noise level of 85 dB (A), it employs a 380V EC motor. There is no need for a complicated volute since the bracket design enables direct installation on top of or next to the motor. Narrow internal cooling channels and filters are overcome by the high static pressure of 900 Pa, guaranteeing that enough cooling air reaches vital parts like windings and bearings to avoid overheating and derating. Megawatt-class motors and diesel generator sets may be adequately cooled by the enormous airflow of 18,600 m³/h. When compared to fixed-speed fans, the EC motor's 0–10V/PWM speed regulation allows for dynamic airflow adjustment based on load rate, saving over 40% on energy. It is the perfect cooling partner for high-voltage motors, exciters, and frequency converters because of its IP55 protection rating, which adapts to industrial dust and oil mist, and its 50,000-hour lifespan, which guarantees dependability in continuous operation situations like power plants and chemical plants.
