Abstract
A filter gasket seals at least one mitered corner of a filter frame having a substantially planar first surface and an adjacent side surface. The gasket includes at least first and second elongated gasket segments formed from compressible material. Each segment has a substantially planar surface adapted to contact the substantially planar first surface of the filter frame. The first and second gasket segments also each include an end which, when brought into joined engagement with the end of the other gasket segment, forms an interlocking miter joint to seal the at least one mitered corner of the filter frame.
Claims39
A filter arrangement comprising a filter gasket that seals at least one mitered corner of the filter frame having a substantially planar first surface substantially transverse to fluid flow through the filter and an adjacent side surface substantially parallel to fluid flow through the filter, at least first and second elongated gasket segments formed from compressible material, each segment having a substantially planar surface adapted to completely overlie and contact the substantially planar first surface of the filter frame, the first and second gasket segments also each including an end which, when brought into joined engagement with the end of the other gasket segment forms an interlocking miter joint to overlap and seal the at least one mitered corner of the filter frame.
A filter arrangement comprising:
- a frame including a plurality of frame segments, each frame segment having a substantially planar first surface substantially transverse to fluid flow through the filter arrangement and an adjacent side surface, the frame segments being joined to form a like plurality of mitered joints;
- an ultra-high grade filter media spanning the frame from within the frame segments;
- and
- a filter gasket that seals the mitered joints of the filter frame, the filter gasket including a like plurality of elongated gasket segments formed from compressible material, each segment having a substantially planar surface completely overlying and contacting the substantially planar first surface of a corresponding filter frame segment and an end which, when brought into joined engagement with the end of another one of the gasket segments forms an interlocking miter joint overlying a corresponding one of the mitered joints of the filter frame.
A filter assembly comprising:
- a filter arrangement comprising a frame including a plurality of frame segments, each frame segment having a substantially planar first surface substantially transverse to fluid flow through the filter assembly and an adjacent side surface, the frame segments being joined to form a like plurality of mitered joints, an ultra-high grade filter media spanning the frame from within the frame segments, and a filter gasket that seals the mitered joints of the filter frame, the filter gasket including a like plurality of elongated gasket segments formed from compressible material, each segment having a substantially planar surface completely overly and contacting the substantially planar first surface of a corresponding filter frame segment and an end which, when brought into joined engagement with the end of another one of the gasket segments forms an interlocking miter joint overlying a corresponding one of the mitered joints of the filter frame;
- and
- a receptacle having wall segments configured to receive the filter arrangement, to compress the interlocking gasket miter joints together and to compress the compressible gasket material along the elongated gasket segments.
