ebm-papst RER 220 TD - S-Force Series Centrifugal Fan, 48 V dc, 1063m³/h, DC Operation, 220 (Dia.) 71mm

The RER Series is unique among centrifugal fans as they work of DC circuits rather than the more common AC units. Switching from AC circuits to DC circuits gives several benefits including safety (lower voltages) and DC units are more energy efficient. This series is available in various options ranging from size, voltage ratings, airflow and certain models have the added benefit of integrated speed control via PWM or analogue voltage.

Centrifugal fans are ideally suited to applications where the required cooling air needs to be conducted at an angle of 90° and especially where high pressure is essential.
