Abstract: A filter assembly can include a filter element and a fluid inlet for fluid to flow through the filter element. The filter assembly can include bypass ports that are in a closed position from bypass port plugs until the filter screen becomes sufficiently clogged such that the fluid is restricted or prevented from flowing through the filter screen, which causes pressure to build up within the filter assembly. The increase in pressure can cause the bypass port plug to open the bypass ports such that fluid can flow through the bypass ports. The filter assembly can include a debris sleeve that partially or wholly surrounds the filter screen.

Abstract: A filter includes filter media and a mesh panel secured to a face of the filter media. The mesh panel has a perimeter edge margin and intersecting web members that extend from the perimeter edge margin across the panel. A web member can have an outer web portion with a larger minimum width than an inner web portion. The web members can define an outer flow opening with a smaller cross-sectional opening than an inner flow opening defined by the web members. The flow openings can be diamond shaped. The web members can include one set of web portions that define an outer flow opening and another set that define an inner flow opening. The sum of the widths of the second set can be less than the sum of the widths of the first set.
