Abstract
An air filter assembly comprises a filter housing having a filter media is mounted therein, and interposed between the inlet and outlet of the housing. An end cap having an annular groove formed therein is mounted to one end of the filter media. A gasket formed of a pliable material is mounted within the groove. The assembly is provided with means for urging the end cap against an adjacent end wall of the housing to compress the pliable gasket therebetween, thereby sealing the inlet from the outlet, and insuring that air passing through the outlet must first pass through the filter media of the filter unit.
Claims17
An air filter assembly, comprising:
- a filter housing having opposing end walls and a side wall between the end walls, said housing having an air inlet and an air outlet formed therein;
- a filter media mounted within said housing and interposed between the inlet and outlet of said housing;
- a metal end cap secured to one end of said filter media, said end cap having a pair of radially spaced annular projections extending from said end cap to form an annular groove in said metal end cap, each of said projections being comprised of a pair of opposed sidewalls interconnected at the distal ends thereof;
- a gasket disposed within said groove, said gasket being formed of a pliable material;
- and
- means for urging said end cap against an adjacent end wall of said housing to compress said gasket therebetween, thereby sealing said inlet from said outlet and insuring that air passing through said outlet must first pass through said filter media.

- an end cap secured to one end of said filter media, said end cap having a groove formed therein by a pair of radially spaced annular projections extending from said end cap, each of said projections being comprised of a pair of opposed sidewalls stamped from said metal end cap;
- a pliable, foamed rubber gasket disposed within said groove;
- and
- means for urging said end cap against an adjacent end wall of said housing to compress said gasket therebetween, thereby sealing said inlet from said outlet so that no air can pass out of said outlet without having first passed through said filter media.
