G3G250-MW50-01 ebmpapst 380-480V 2400W centrifugal blower

Description

The ebmpapst G3G250-MW50-01 is an extremely high-performance 250 mm EC Centrifugal Fan (Backward Curved) utilizing GreenTech EC technology for superior energy efficiency. It operates on a nominal voltage of 400 VAC (380-480 VAC range) at 50/60 Hz. The fan achieves a high nominal speed of 6100 RPM, with a maximum power consumption of 2400 W and a current draw of 4.0 A. This fan is engineered for high static pressure, offering a peak air flow of 1165 m³/h and an impressive maximum static pressure of 4000 Pa (16.06 inAq) at its optimum efficiency point. It features an integrated Ball Bearing motor (M3G112-EA), durable die-cast aluminum housing, and includes an advanced 0-10 VDC / PWM control interface, Tach output, and motor/electronics protection, making it ideal for high-end industrial burners and advanced gas condensing boiler systems.
