Abstract
A security vent includes a housing, a drawer and a latch. The housing includes first and second ends defining a passageway in which the drawers receive. The drawer includes a filter receiving slot. The drawer is movable in and out of the passageway to provide access to the filter receiving slot such that a filter can be inserted and removed therefrom. The latch assembly allows the drawer to be locked in a closed position and unlocked for opening. In another embodiment of the invention, a security vent mountable to the existing air duct inlet opening includes a housing assembly having a mounting frame and a housing wall secured to the mounting frame. The housing wall includes a front faced space from the mounting frame. The front face is perforated. The housing wall and mounting frame define a filter receiving region for holding an air filter. A door is secured to the housing wall and may be moved between an open position and a closed position to either permit or prevent access to and from the filter receiving region. The vent further includes a latch assembly for locking the door in a closed position. In another embodiment of the invention, a system for ventilating an enclosed region includes a secure vent affixed to the wall of the region, the vent including a removable filter. An access door is provided and is movable between a closed position and an open position to either permit or prevent access to the filter.
