ABSTRACT:
A ventilation system for a vehicle to pressurize the cargo area of the vehicle including a duct mounted adjacent the top wall of the vehicle cab with a first end in flow communication with an opening in the front wall of the vehicle, and a second end in flow communication with the cargo area of the vehicle. An adjustable damper is disposed within the duct adjacent the first end. The damper is adjustable between a closed position and an opened position to adjust the amount of air flow through the duct. The center portion of the duct includes a plurality of apertures to direct a portion of the air flowing through the duct into the cab. The lower wall of the center portion includes a plurality of diagonal channels to collect water and direct it to a drain adjacent the first end of the duct. A fan is mounted within the duct to provide air flow into the cargo area when the vehicle is not moving. A filter is also mounted within the duct to prevent dust and particulate matter from entering the cargo area.
