Abstract
A ventilating system for a vehicle cab includes a blower which draws fresh air from the exterior of the cab into the interior of the cab. A filter housing is inserted generally transverse to the direction of air flow through a service opening in the ventilating system into the channel through which the fresh air flows. The filter housing encloses a fresh air filter. The blower also draws recirculating air from the interior of the cab through a recirculating air intake opening and blows it back through a recirculating air filter into the cab through an outlet opening. The recirculating air filter is also mounted in the filter housing. A filter insert includes a filter housing which contains the fresh air filter and the recirculating air filter, which are adjacent each other on either side of a separating wall, fresh air and recirculating air are separately filtered.
