Description
The ebmpapst A3G400-AC22-52 is a high-efficiency 400 mm EC Axial Fan (EC motor with AC input) designed for a wide voltage range of 200 VAC to 277 VAC, compatible with both 50 Hz and 60 Hz networks. It operates at a nominal speed of 1630 RPM, providing a maximum air flow of approximately 3605 m3/h (free air) and a maximum static pressure of 160 Pa (0.64 inAq). The fan consumes 400 W of power and draws 2.6 A at maximum load. Featuring an IP54 protection rating and a 0-10 VDC / PWM control interface, this fan is ideal for robust, high-performance, and speed-controllable industrial ventilation, refrigeration, and air conditioning applications.
