Pentair High Flow Filter Industrial Large-Diameter Pleated Filtration Solution

Pentair High Flow Filter is a professional large-diameter pleated filtration solution launched by Pentair, specially designed for high-capacity industrial water pretreatment and membrane security filtration scenarios. Widely installed in horizontal FRP filter housings, it is commonly matched with HFU660CAS010JUW large flow filter element and forms a complete industrial water purification pretreatment chain with PFTM102UEPFA high flow filter cartridge. Pentair High Flow Filter adopts high-precision multi-layer gradient polypropylene pleated media, featuring ultra-large effective filtration area, ultra-low initial pressure drop and superior dust holding capacity. It efficiently intercepts suspended solids, fine sediment, colloidal particles and tiny impurities in raw water, effectively protecting downstream reverse osmosis and ultrafiltration membrane elements from abrasion, scaling and premature fouling. With standardized integral structure, excellent chemical compatibility and fast plug-and-play replacement design, Pentair high flow filters have become the preferred standard filtration equipment for large seawater desalination, power plant water supply, petrochemical process water and industrial wastewater reuse projects worldwide.

Product Description

Pentair High Flow Filter represents the classic high-flow filtration technology of Pentair Aqualine series, covering mainstream industrial specifications such as 60-inch length and 6.75-inch large outer diameter. It is a core disposable pleated filter cartridge for heavy-duty industrial microfiltration, focusing on solving the pain points of small flow, easy blockage and frequent replacement of traditional ordinary filter cartridges. The whole filter element adopts full food-grade polypropylene integrated structure, including reinforced inner and outer support cages, multi-layer gradient composite pleated media, injection-molded reinforced end caps and high-elastic sealing gaskets.

All structural connections of Pentair High Flow Filter adopt thermal fusion welding process without any adhesive bonding, completely eliminating the risk of secondary water pollution caused by glue dissolution. The unique dense deep-pleated design greatly expands the effective filtration area per unit cartridge, realizing ultra-high single-element water flow, which can effectively reduce the total number of filter cartridges and filter housing volume required by the system. It supports multiple precision grades from 1μm to 90μm, fully adapting to different raw water quality and pretreatment process requirements.

This Pentair high flow filter follows the mature outside-in filtration principle, which concentrates intercepted pollutants on the outer layer of the filter media to avoid impurity leakage and downstream pipeline contamination. It can stably control the SDI value of inlet water below 5, meeting the strict water inlet standards of high-precision membrane systems. Widely applicable for seawater desalination pretreatment, boiler makeup water filtration, petrochemical process liquid purification, electronic ultrapure water preparation and industrial reclaimed water reuse. It is widely recognized by engineering contractors and end users for stable batch consistency, strong interchangeability and low long-term operating cost.

Working Principle

Pentair High Flow Filter operates based on outside-in cross-flow microfiltration technology. Untreated industrial raw water enters the closed filter housing and uniformly flows to the outer surface of the pleated filter media. Under the action of water pressure, large-particle sediment, suspended impurities and macroscopic flocs are trapped on the outer layer of the filter media, while tiny colloids and fine particles are intercepted layer by layer through the gradient internal filter layer.

After full filtration and purification, clean water penetrates the filter media, converges into the central inner support pipe, and flows out evenly to enter the downstream membrane treatment system. The gradient filter media structure realizes coarse filtration outside and fine filtration inside, which significantly improves the dirt holding capacity and delays the pressure rise rate. With the continuous accumulation of intercepted pollutants, the inlet and outlet differential pressure of the filter cartridge gradually increases. When the pressure difference reaches the standard alarm threshold of 25–30 PSID, the operator needs to replace the Pentair high flow filter cartridge in time to restore the system’s rated water flow and filtration efficiency.

The all-polypropylene material has excellent acid and alkali resistance and oxidation resistance, adapting to most neutral aqueous solutions and conventional chemical cleaning environments. The reinforced internal and external support structure effectively resists medium expansion and deformation under high-flow water impact, preventing fluid bypass and ensuring 100% full-flow filtration effect throughout the service cycle.
