Abstract
A filter assembly, panel filter element, and servicing method is provided for reducing inlet flow restriction from a housing inlet into an inlet plenum and reducing outlet flow restriction from an outlet plenum to a housing outlet.
Claims17
A filter assembly comprising a housing having an inlet and an outlet, a panel filter element in said housing for filtering fluid flowing from said inlet to said outlet, said panel filter element dividing said housing into an inlet plenum and an outlet plenum, said panel filter element being configured to:
- a) reduce inlet flow restriction from said inlet, to said inlet plenum;
- and b) reduce outlet flow restriction from said outlet plenum to said outlet, wherein fluid flows along an axial direction in at least one of said inlet and outlet plenums, and flows transversely through said panel filter element from said inlet plenum to said outlet plenum, said inlet plenum and said outlet plenum are transversely spaced on opposite sides of said panel filter element therebetween, wherein said panel filter element extends obliquely relative to said axial direction, and wherein the volume of said inlet plenum increases as fluid progresses away from said inlet, and the volume of said outlet plenum decreases as fluid progresses towards said outlet.
A filter assembly comprising a housing having an inlet and an outlet, a panel filter element in said housing for filtering fluid flowing from said inlet to said outlet, said panel filter element dividing said housing into an inlet plenum and an outlet plenum, said panel filter element being configured to:
- a) reduce inlet flow restriction from said inlet to said inlet plenum;
- and b) reduce outlet flow restriction from said outlet plenum to said outlet, wherein said panel filter element has a border frame having distally opposite first and second endwalls, said first endwall being proximate said inlet, said second endwall being proximate said outlet, each said endwall having a height extending along the direction of fluid flow through said panel filter element, wherein the height of said first endwall is different than the height of said second endwall.
A filter assembly comprising a housing having an inlet and an outlet, a panel filter element in said housing for filtering fluid flowing from said inlet to said outlet, said panel filter element dividing said housing into an inlet plenum and an outlet plenum, said panel filter element being configured to:
- a) reduce inlet flow restriction from said inlet to said inlet plenum;
- and b) reduce outlet flow restriction from said outlet plenum to said outlet, wherein fluid flows along an axial direction in at least one of said inlet and outlet plenums, and flows transversely through said panel filter element from said inlet plenum to said outlet plenum, said inlet plenum and said outlet plenum are transversely spaced on opposite sides of said panel filter element therebetween, and wherein said housing comprises a base and a cover meeting at an interface split line, and wherein at least one of said split line and said panel filter element extends obliquely relative to said axial direction, wherein said split line extends parallel to said axial direction, and said panel filter element extends obliquely relative to said axial direction.
A filter assembly comprising a housing having an inlet and an outlet, a panel filter element in said housing for filtering fluid flowing from said inlet to said outlet, said panel filter element dividing said housing into an inlet plenum and an outlet plenum, said panel filter element being configured to:
- a) reduce inlet flow restriction from said inlet to said inlet plenum;
- and b) reduce outlet flow restriction from said outlet plenum to said outlet, wherein fluid flows along an axial direction in at least one of said inlet and outlet plenums, and flows transversely through said panel filter element from said inlet plenum to said outlet plenum said inlet plenum and said outlet plenum are transversely spaced on opposite sides of said panel filter element therebetween, and wherein said housing comprises a base and a cover meeting at an interface split line, and wherein at least one of said split line and said panel filter element extends obliquely relative to said axial direction, wherein said split line and said panel filter element extend in non-parallel relation to each other.
A filter assembly comprising a housing having an inlet and an outlet, a panel filter element in said housing for filtering fluid flowing from said inlet to said outlet, said panel filter element dividing said housing into an inlet plenum and an outlet plenum, said panel filter element being configured to:
- a) reduce inlet flow restriction from said inlet to said inlet plenum;
- and b) reduce outlet flow restriction from said outlet plenum to said outlet, wherein fluid flows transversely through said panel filter element from said inlet plenum to said outlet plenum, said housing comprises a base and a cover meeting at an interface split line, said panel filter element has a border frame for mounting and sealing said panel filter element in said housing, each of said base and said cover has a respective set of shelves engaging and trapping said border frame in mounted and sealed relation therebetween at least one of said shelves being transversely spaced from said split line.
