ABSTRACT:
An air distribution system for a vehicle cab is disclosed herein. Fresh air is drawn into the system, filtered and transferred to the interior of the vehicle cab. The system uses a blower for transferring air into the cab with all fresh air passing first through a fresh air filter. The fresh air filter has air flow from a hollow interior out through air permeable sides. This air flow traps particulates within the interior of the filter which is then easily removed from an air filter chamber without emptying dirt into the chamber or on the operator. Furthermore during operation, accumulated dust and dirt is kept within the filter and does not drop off on or around the cab. This system may be used for simple ventilation or may be combined with other air conditioning and air recirculation means thereby providing a total vehicle ventilation system.
