Abstract
The invention disclosed here is a filter cap device for releasably mounting large filters to a barrier wall. The filter cap has an oversize radius overlapping a filter opening in the wall. A plurality of hand-operated outboard locking devices releasably connect the cap to the wall. Likewise, a plurality of hand-operated inboard locking devices releasably connect the cap to the filter. The cap has a central opening which defines an air passageway from the filter through the wall. When it is desired to replace a filter, the filter cap and filter can be removed from the opening as a single unit, followed by disconnecting the used filter from the filter cap. A replacement filter is then attached to the cap and the entire unit is reinstalled.
