Abstract (en)
[origin: US4971518A] In a radial fan suitable in particular for traction vehicles, 10-15% of the conveyed air quantity is diverted radially from the cooling-air path by guide devices (10) which at the same time serve as a separator; the main proportion passes to the coolers after a 90 DEG deflection. In this way, dirt particles such as dust, snow, spray water, etc, are effectively kept away from the coolers.
