Abstract
A filter unit is removably attached to a machine housing over an air intake vent to prevent particulate matter from entering the machine and thereby damaging the machine. The filter unit includes a filter, a filter housing, and fasteners to removably attach the filter housing to the machine. The filter unit can be retro-fit by a user of the machine or can be attached during manufacturing.
Claims7
A filter unit for preventing particulate matter from entering an air intake vent in a machine housing of a machine, said filter unit comprising:
- an air filter;
- a filter housing for removably receiving said air filter;
- and
- attachment means for removably attaching said filter housing to said machine housing in a location such that said filter extends over the entire air intake vent of said machine housing;
- said filter housing comprises two parts placed end to end collectively forming four side walls, said four side walls each having a length, a near edge and a far edge, a mounting flange extending perpendicularly outward from each said near edge of said four side walls along said length thereof, a top flange extending perpendicularly inward from each said far edge of said four side walls along said length thereof, and a housing cover having at least one opening mounted to said top flanges, said attachment means placed in association with said mounting flanges;
- said filter being removable from said filter housing upon detaching one of said two parts of said filter housing from said machine housing.
A filter unit for preventing particulate matter from entering an air intake vent in a machine housing of a machine, said filter unit comprising:
- an air filter;
- a filter housing for removably receiving said air filter;
- and
- attachment means for removably attaching said filter housing to said machine housing in a location such that said filter extends over the entire air intake vent of said machine housing;
- said filter housing comprises first and second rectangular box-shaped mounting elements each having an end wall and four side walls and defining an opening for receiving an end of said filter, said attachment means placed in association with one of said four side walls;
- said first box shaped mounting element placed on one end of said air intake vent, and said second box shaped mounting element placed on an opposite end of said air intake vent;
- said filter being removable from said filter housing while said filter housing is attached to said machine housing.
A filter unit in combination with an electro-mechanical machine for preventing particulate matter from entering an air intake vent in a housing of said machine, said filter unit comprising:
- an air filter;
- a double box end filter housing for removably receiving said air filter;
- and
- attachment means for removably attaching said filter housing to said machine housing in a location such that said filter extends over the entire air intake vent of said machine housing;
- said filter housing comprises two parts placed end to end collectively forming four side walls, said four side walls each having a length, a near edge and a far edge, a mounting flange extending perpendicularly outward from each said near edge of said four side walls along said length thereof, a top flange extending perpendicularly inward from each said far edge of said four side walls along said length thereof, and a housing cover having at least one opening mounted to said top flanges, said attachment means placed in association with said mounting flanges;
- said filter being removable from said filter housing upon detaching one of said two parts of said filter housing from said machine housing.
