Abstract
A device for sealing filters in a dust collector. The preferred dust collector has a housing enclosing clean-air and dirty-air chambers, a support base in the housing having a support side and an opposite side, and a contact surface spaced from the support base and facing the support side. A filter is positioned between the contact surface and support side. A push, lift or hold-release device is provided to secure the filter in sealed engagement with the support side and the contact surface. In a “hold” position, said device secures the filter with respect to the housing. In a “removal” position, said device permits the filter to be removed from the housing.
