Abstract
A filter element with an improved mounting frame and method of assembly are provided. The filter element includes a filter media pack with a mounting frame attached to the outer periphery of the filter media pack. The mounting frame defines a channel that holds a shut-off material for preventing leakage of an adhesive securing the mounting frame to the filter media pack. A filter element that includes a polymeric material between the filter media pack and the adhesive is also provided. The shut-off material may be pre-formed or applied in a flowable state.
Claims35
A filter element comprising:
- a filter media pack having first and second flow faces and an outer periphery extending therebetween;
- a mounting frame positioned axially between the first and second flow faces and in surrounding relation of the outer periphery, the mounting frame including an inner wall and an outer wall connected to the inner wall, the inner wall being positioned radially inward of the outer wall, the inner wall and outer wall forming a channel therebetween;
- a shut-off material positioned within the channel and extending out of the channel and into radial contact with the outer periphery of the filter media pack, the shut-off material, outer wall and outer periphery defining a cavity;
- and
- an adhesive located within the cavity and securing the mounting frame to the filter media pack.

A method of forming a filter element comprises:
- providing a filter media pack having first and second flow faces and an outer periphery extending therebetween;
- installing a mounting frame axially between the first and second flow faces and in surrounding relation of the outer periphery, the mounting frame including an inner wall and an outer wall connected to the inner wall, the inner wall being positioned radially inward of the outer wall, the inner wall and outer wall forming a channel therebetween;
- dispensing a shut-off material into the channel;
- allowing the shut-off material to rise out of the channel and into radial contact with the outer periphery of the filter media pack such that the shut-off material, outer wall and outer periphery defining a cavity;
- and
- dispensing an adhesive into the cavity and securing the mounting frame to the filter media pack.

A filter element comprising:
- a filter media pack having first and second flow faces and an outer periphery extending therebetween;
- a polymeric coating covering at least a portion of the outer periphery of the filter media pack and defining an outer surface;
- a mounting frame positioned axially between the first and second flow faces and in surrounding relation of the polymeric coating, the mounting frame including an inner wall and an outer wall connected to the inner wall, the inner wall being positioned inward of the outer wall, the outer wall being spaced outward from an outer periphery of the polymeric coating forming a gap therebetween;
- a shut-off material positioned within the gap and extending into radial contact with the outer surface of the polymeric coating and the outer wall, the shut-off material, outer surface of the polymeric coating and outer wall defining a cavity;
- and
- an adhesive located within the cavity and securing the mounting frame to the filter media pack.
