Description
The ebmpapst W3G800-LV05-03/F01 is a high-capacity industrial EC axial fan with a nominal voltage of 400 VAC and dimensions of 970 x 970 x 350 mm, specifically engineered for large-scale air handling units and industrial cooling applications requiring high static pressure. Driven by a high-torque M3G150-NA GreenTech EC external rotor motor with a maximum power consumption of 3500 W and a current draw of 5.3 A, this unit features a heavy-duty dual ball bearing system designed for long-term mechanical stability and continuous S1 duty. Its advanced aerodynamic design, incorporating PP plastic guide vanes and an internal diffuser, delivers a powerful balance of massive airflow and high back pressure up to 350 Pa, making it highly effective at maintaining air circulation in industrial halls and commercial HVAC systems. Constructed with a galvanized and black plastic-coated sheet steel housing and a die-cast aluminum electronics enclosure, this 51.4 kg fan provides a dependable and energy-saving cooling solution with integrated Modbus-RTU interface and thermal overload protection for data centers and large-scale infrastructure at the end.
