Rotatable sealed filter outlet

A air filter comprising:

• a housing having distally opposite axial ends;
• a cylindrical filter element in said housing, said cylindrical filter element having an annular sidewall with a hollow interior and extending between distally opposite axial ends, wherein air flows radially inwardly through said annular sidewall into said hollow interior and then axially through said hollow interior;
• an outlet tube extending axially through one of said axial ends of said housing and communicating with said hollow interior of said cylindrical filter element for exhausting air therefrom;
• a first seal axially engaged between one of said axial ends of said cylindrical filter element and said one axial end of said housing in axial sealed relation;
• a second seal engaged between said outlet tube and said one axial end of said housing in sealed relation.
