The Whisper 3C fan's greatest advantage is its very small dimensions, optimised to fit in small spaces. Whisper 3C is a heating fan mainly intended for heating systems for minibuses and citybuses. The heating fan, which is of a very compact design, consists of a heating core with 22 mm connection and an axial fan for 24 VDC voltage. The entire fan is housed in an aluminium box. In one simple operation, the heater core can be turned from the left to the right side and vice versa. You simply unscrew the side plate, remove the heating core, turn it round and mount it back again. Product info Installation instructions Spare parts
