Pleated Filter Element
Definition
A filter whose media is folded into pleats to pack a large surface area into a compact element, lowering pressure drop and extending life.
Pleating multiplies the effective filtration area within the same envelope, so a pleated high-flow element offers much lower ΔP and higher dirt-holding capacity than an equivalent depth cartridge.
Most absolute-rated high-flow elements use pleated PP or glass-fiber media with outside-to-inside flow to make full use of the pleat area.
Relevance for high-flow filtration
R+F pleated high-flow elements replicate OEM pleat geometry and area for equivalent flow and service life.

A flow configuration in which liquid enters the outer surface of the element and exits through the core, using the full pleat area for filtration.
Glass Fiber (GF) Filter MediaA high-efficiency, absolute-rated pleated medium made from fine borosilicate glass microfibers, used for demanding fine filtration.
Dirt-Holding CapacityThe total mass of contaminant a filter element can retain before reaching its change-out differential pressure.
High-Flow FilterA large-format filter element designed to process very high liquid flow rates through a single cartridge, reducing the number of elements, housing size, and change-out labor compared with standard cartridges.
