High Flow Filter Cartridge 5 Micron 20 Inch: Compact Large Diameter Pleated Filter For Medium Precision Small-Scale Water Pretreatment
Introduction:If you are sourcing High Flow Filter Cartridge 5 Micron 20 Inch for compact water treatment skids, small RO pre-treatment and medium-precision liquid filtration projects with limited installation space, this 5μm short large-diameter pleated filter balances stable filtration accuracy and high throughput. Compared with 40-inch long high flow cartridges, the 20-inch compact design fits smaller filter housings while retaining deep pleated PP media structure. It effectively intercepts fine silt, tiny rust particles, suspended solids and colloidal contaminants. It serves as reliable pre-filter protection for small RO and UF membrane systems to reduce membrane fouling risk. With glue-free thermal bonding technology, low pressure drop and simple replacement operation, this compact filter is widely used in food and beverage production, industrial circulating water and small chemical process liquid purification.

Product Overview
High Flow Filter Cartridge 5 Micron 20 Inch is the shortened compact version of our 40-inch 5μm high flow filter, developed for projects with restricted installation space. It adopts high-purity virgin polypropylene filter media and deep pleated forming technology. Integrated thermal welding eliminates chemical adhesives entirely, preventing organic precipitation and secondary liquid contamination. Even with 20-inch shorter length, it maintains the 115mm large outer diameter to guarantee sufficient effective filtration area. The stable 5μm pore structure removes fine particulate impurities that may damage downstream membrane elements. Optional universal end caps match compact large-flow filter housings, supporting quick plug-and-play installation. It is the ideal medium-precision filtration choice for small and medium water treatment systems.
Working Principle
This 5 micron 20-inch high flow filter cartridge adopts outside-in pleated surface filtration principle. When raw water and process liquid pass through dense deep pleated media, coarse suspended impurities are trapped on the outer pleat surface, fine particles and colloids above 5μm are captured by the inner high-density PP filter layer. Optimized pleat spacing balances flow rate and filtration precision, avoiding sudden pressure rise and slowing down clogging speed. All sealing joints use thermal fusion welding to prevent liquid bypass and ensure full-flow effective filtration. Thickened reinforced inner core withstands differential pressure fluctuation, keeping pleat structure intact and stable 5μm filtration accuracy during continuous 24-hour operation.

FAQ
Q1: When should I pick 5μm 20 inch high flow filter?
A1: It is suitable for small skids requiring medium precision filtration. It works as standard pre-filter for compact RO systems to capture fine particles before membrane modules.
Q2: Is this filter compatible with existing 20-inch large flow filter housing?
A2: Yes, standard 115mm outer diameter and end cap options fit most mainstream 20-inch large flow filter housings.
Q3: Is it disposable?
A3: Yes, it belongs to disposable pleated filter cartridge. Once clogged, cleaning cannot recover original filtration performance, direct replacement is required.
Q4: Can customized end caps be supplied for bulk orders?
A4: Yes, DOE, SOE and other end cap styles, special customized options are available for bulk project orders.
