Description
The ebmpapst K2D250-AH06-06 is a robust AC Centrifugal Fan (also referred to as a diagonal fan) designed to deliver high-pressure stability and airflow. It is commonly integrated into the Rittal SK 3244.140 TopTherm Filter Fan Unit for industrial enclosure ventilation. The fan operates on a dual-frequency, three-phase voltage, with a power consumption of 93 W at 50 Hz (400 V AC) and 140 W at 60 Hz (460 V AC). It utilizes a high-efficiency M2D068-DF motor and achieves speeds up to 2930 min⁻¹. The fan unit, including a filter mat, is rated with an IP 54 degree of protection and is suitable for continuous operation in ambient temperatures from −30 °C to 55 °C.
