The R1G220-RD61-03 from EBM-Papst is a DC-powered centrifugal fan with backward-curved blades, specially developed for demanding vehicle environments. The fan combines a RadiCal fan impeller made of PA plastic with a brushless EC motor and a robust housing made of cast, black-painted aluminum. Thanks to IP6K9K protection for the electronics and IP24KM for the motor, it handles moisture and dust without problems.
The fan is perfectly suited for vehicle-mounted ventilation and cooling systems where high performance, compact size, and reliable operation are crucial. Soft start, current limitation, and reverse polarity protection make it easy to integrate into existing systems.
