Filter with engine integrity protection
A filter system includes a designated filter element including a geometric projection thereon and a filter element housing including an opening keyed to the geometric projection. The opening comprises a recess, a channel or a slot and the recess, the channel, or the slot includes a rib. The geometric projection engages the opening when the designated filter element is installed in the filter element housing, and the filter element housing includes a filter housing body and a filter housing cover.
1. A filter system comprising:
a designated filter element comprising a filter element frame including a geometric projection extending therefrom along a longitudinal axis of the designated filter element the geometric projection comprising a gap portion; and
a filter element housing including an opening keyed to the geometric projection, wherein the opening comprises a recess, a channel or a slot, wherein the recess, the channel, or the slot includes a rib positioned within the opening and extending away from the recess, the channel, or the slot along the longitudinal axis, the rib keyed to the gap portion of the geometric projection;
wherein the geometric projection engages the opening when the designated filter element is installed in the filter element housing, and wherein the filter element housing comprises a filter housing body and a filter housing cover.
2. The system of claim 1 , wherein the recess, channel or slot has a form such that non-designated filter elements with higher performance than the designated filter element may be installed in the filter housing.
3. The system of claim 1 , wherein the recess, channel or slot has a form such that non-designated filter elements with lower performance than the designated filter element are prevented from installation in the filter housing.
4. The system of claim 1 , wherein the recess, channel or slot has a form such that non-designated filter elements with a shorter length than the designated filter element are prevented from installation in the filter housing.
5. The system of claim 1 , wherein the geometric projection consists of one of a rectangular, square, triangular, trapezoidal, double lobed, oval, parallelogram, T-shaped, cross-shaped, pie-shaped, and heart-shaped form.
6. The system of claim 1 , wherein the designated filter element comprises a direct flow filter element.
7. The system of claim 1 , wherein the designated filter element comprises a plurality of geometric projections.
8. A filter element comprising:
a filter element frame;
a filter media; and
a geometric projection extending from the filter element frame along a longitudinal axis of the filter element, the geometric projection comprising a gap portion, the geometric projection, configured to engage an opening of a designated filter element housing when the filter element is installed in the designated filter element housing, the opening including a rib within the opening and extending away from the opening along the longitudinal axis, the geometric projection keyed to the opening and gap portion keyed to the rib.
9. The filter element of claim 8 , wherein the geometric projection consists of one of a rectangular, square, triangular, trapezoidal, double lobed, oval, parallelogram, T-shaped, cross-shaped, pie-shaped, and heart-shaped form.
10. The filter element of claim 8 , wherein the filter element comprises a direct flow filter element.
11. The filter element of claim 8 , wherein the filter element comprises a plurality of geometric projections.
12. A filter element housing comprising:
a filter element housing body and a filter element housing cover, wherein the filter element housing includes an opening keyed to a geometric projection of a designated filter element, the opening comprises a recess, a channel, or a slot including a rib positioned within the opening and extending, away from the recess, the channel, or the slot along the longitudinal axis, the rib keyed to a gap portion of the geometric projection, and the opening is configured to engage the geometric projection extending from the designated filter element along a longitudinal axis of the designated filter element when the designated filter element is installed in the filter element housing.
13. The filter element housing of claim 12 , wherein the recess, channel or slot has a form such that non-designated filter elements with higher performance than the designated filter element may, be installed in the filter housing.
14. The filter element housing of claim 12 , wherein the recess, channel or slot has a form such that non-designated filter elements with lower performance than the designated filter element are prevented from installation in the filter housing.
15. The filter element housing of claim 12 , wherein the recess, channel or slot has a form such that non-designated filter elements with a shorter length than the designated filter element are prevented from installation in the filter housing.
