Description
The ebmpapst K3G310-BB49-02 is a high-efficiency 400 VAC 3-phase EC Centrifugal Fan module featuring a backward-curved 7-blade sheet aluminum impeller with a size of 310 mm, single-intake design, and an integrated painted black steel support bracket. Constructed with a die-cast aluminum electronics housing, galvanized sheet steel support plate and inlet nozzle, painted black rotor, and maintenance-free ball bearings, it has a total weight of 22.1 kg. Driven by an energy-efficient M3G112-GA 3-phase EC motor operating across a voltage range of 380 – 480 VAC at 50 / 60 Hz, it draws a rated current of 2.5 A with a power consumption of 1650 W. Operating at a nominal speed of 3140 RPM under max. load, it produces a max. air flow of 1786.3 CFM (3035.0 m³/h / 50.58 m³/min) and a max. static pressure of 114.62 mmH₂O (1124.0 Pa / 4.51 inAq). Engineered for an operating temperature range of -25 to +60 °C (transport/storage temperature range of -40 to +80 °C), it features IP54 degree of protection, Class B insulation, Class I protection rating, F4-1 moisture/environmental protection class, internal thermal overload protection, 0-10 V / PWM control, RS-485 MODBUS-RTU, integrated PID controller, terminal box electrical connection, ErP 2015 efficiency compliance (ηes 61.1%), and complies with CE, EAC, and UL agency approvals.
