The W3G250-HK19-11 from EBM-Papst is a compact and powerful EC axial fan in a 280 × 280 × 80 mm format, driven by an electronically commutated motor for high efficiency and low energy consumption. The fan delivers an airflow of up to 1120 m³/h at 2700 rpm and is ideal for demanding ventilation projects where energy efficiency and operational reliability are crucial.
Thanks to built-in support for 0–10 V DC and PWM control, as well as tach output for speed feedback, the fan is ideal for systems requiring precise regulation. The robust construction with a die-cast aluminum housing and IP54 protection class makes it suitable even in harsher environments.
