Abstract

A filter system includes a housing having an inlet opening surrounded by a sealing surface, an outlet opening, and a door having a seating surface surrounding a through-port opening. The door is movable between an open and closed position and a closed position. In an embodiment, a hinge connects the door to the housing, such that the door pivots between open and closed positions about the hinge. A panel pre-filter is seated along the seating surface of the door. A V-bank filter is positioned in the inlet opening, and has a flange in general alignment with the sealing surface, and has a plurality of filter media sections projecting away from the flange and into the housing interior. A latch is adapted to keep the panel pre-filter positioned inline and upstream of the V-bank filter. A seal is disposed between the flange of the V-bank filter and the sealing surface.
