Filter system, filter mounting mechanism, and filter elements used in and with the filter system and filter mounting mechanism

A filter element comprising:

• a tube of filter media extending axially between a first end and a second end and defining a central cavity, the tube of filter media being frustoconical increasing in radial dimension when moving along a central axis from the second end towards the first end, the tube of filter media extending at a first angle relative to the central axis, the filter media of the tube of filter media having a radially inner most edge at the first end;
• a seal member attached to a first end of the tube of filter media, the seal member having a radially inward facing tapered inner surface, the tapered inner surface extending at a second angle relative to the central axis;
• and
• the first angle being more parallel to the central axis than the second angle;
• wherein:
• the tapered inner surface of the seal member has a first surface edge, the first surface edge being an axially outermost extent of the tapered inner surface of the seal member that is spaced axially the furthest from the first end of the tube of filter media, the first surface edge is positioned radially outward of the inner most edge of the tube of filter media at the first end;
• the tapered inner surface of the seal member has a second surface edge opposite the first surface edge, the second surface edge being closer to the second end of the tube of filter media than the first surface edge, the second surface edge is positioned radially inward of the first surface edge and radially inward of the inner most edge of the tube of filter media at the first end.

A filter system comprising:

• a tube sheet defining a flow aperture therethrough;
• a filter element mounted to the tube sheet, the filter element including:
• a tube of filter media defining a central cavity, the tube of filter media extending between first and second ends along a central axis, the first end being adjacent the tube sheet;
• a first seal member attached to the first end of the tube of filter media, the first seal member being annular and defining a flow opening in fluid communication with the central cavity, the first seal member including a radially inward facing surface, the radially inward facing surface is tapered at a first angle relative to the central axis of the tube of filter media such that the radially inward facing surface is spaced further from the central axis when moving axially away from the tube of filter media;
• wherein:
• the seal member is annular;
• the seal member includes:
• an annular sealing rib extending axially outward and away from the tube of filter media;
• a first annular abutment shoulder extending axially outward and away from the tube of filter media, the first annular abutment shoulder spaced radially from the annular sealing rib forming a first channel therebetween.
