ABSTRACT:
The disclosure provides a system for mounting and sealing a filter in a vacuum cleaner, such as a wet and dry vacuum cleaner, that concentrates compressive sealing forces on a specific, relatively thin seal portion rather than the filter body as a whole. The concentrated compressive stress provides a well-defined region to consistently provide a sealing engagement. A portion of the seal is positioned into an undercut portion of a mounting assembly and is compressed or “pinched” between opposing surfaces to cause the sealing. Further, one or more of the surfaces are movable to compress the seal portion therebetween by actuation of a rotatable filter clamp engageable with a cam. The filter clamp translates toward the seal portion as the filter clamp is rotated along a sloped surface of the cam to engage and clamp the seal portion between the surfaces.
