Product Description
Pentair High Flow Filter Cartridge belongs to the well-known Pentair Aqualine high-flow filtration product line, represented by mainstream models ALN01-60B, ALN05-60B and other specifications. The standard size is 60-inch length and 6.75-inch outer diameter, adopting full polypropylene integrated structure, including reinforced inner and outer support cages, gradient pleated polypropylene filter media, injection reinforced end caps and elastic sealing gaskets. All connection joints adopt thermal fusion welding technology without adhesive, eliminating risks of glue dissolution and secondary contamination to process fluid.
This series filter follows mature outside-in flow design. Multiple nominal precision grades ranging from 1μm to 90μm are available to meet diversified security filtration demands ahead of membrane separation equipment. Dense pleated layout greatly expands effective filtration area, achieving remarkable single-element flow capacity compared with conventional 2.5-inch wound filter cartridges. It can efficiently capture tiny particles escaping multimedia filtration and activated carbon units, stably controlling feed water SDI value below 5 to satisfy strict inlet requirements of seawater reverse osmosis systems.
Built-in integral handle simplifies on-site extraction and replacement without extra auxiliary fixtures. Multiple Pentair high flow cartridges can be installed in parallel inside horizontal filter housings, greatly reducing the total number of filter elements and minimizing the footprint of pretreatment equipment. This filter cartridge is extensively applied in seawater desalination pretreatment, boiler feed water filtration, petrochemical process liquid purification, industrial reclaimed water reuse and electronic ultrapure water production. System integrators and end users choose Pentair High Flow Filter Cartridge for new skid-mounted water treatment systems and daily spare part renewal.
Working Principle
Pentair High Flow Filter Cartridge operates based on outside-in cross-flow microfiltration mechanism. Untreated raw liquid enters the filter housing and flows toward the outer surface of pleated filter media. Suspended particles, sediment and colloidal impurities are captured on the surface and inner layers of gradient polypropylene media. Purified liquid penetrates filter layers, converges inside the central support core and flows out as qualified filtrate.
Large pleated filtration area maintains low flow resistance under continuous high-flow operating conditions. During long-term running, intercepted pollutants accumulate gradually, leading to slow growth of inlet-outlet differential pressure. Operators need to replace the filter cartridge once differential pressure reaches 25–30 PSID threshold to recover system water throughput. Polypropylene raw material provides excellent chemical compatibility, compatible with neutral aqueous liquid and regular acid-base cleaning solutions for filter housing maintenance. Rigid reinforced support cages prevent medium deformation under water pressure impact, avoid fluid bypass and guarantee stable particle interception efficiency throughout service life.

FAQ
Q1: What typical models belong to Pentair High Flow Filter Cartridge Aqualine series?
A1: The mainstream specifications include ALN01-60B, ALN05-60B, ALN10-60B and ALN20-60B. Different micron ratings can be selected according to raw water quality and membrane system requirements.
Q2: Can Pentair High Flow Filter Cartridge be cleaned and reused after fouling?
A2: Pentair Aqualine pleated polypropylene cartridge belongs to disposable filter element. Conventional chemical cleaning cannot fully restore flux after severe contamination. It is recommended to replace once differential pressure exceeds 25–30 PSID alarm limit.
Q3: What maximum continuous operating temperature can Pentair high flow filter cartridge withstand?
A3: Standard polypropylene version supports continuous working temperature up to 54.4°C (130°F). Contact our engineers if customized high-temperature resistant versions are required.
Q4: What inlet water index is recommended when using this cartridge for RO security filtration?
A4: It is advised to control feed water SDI ≤5, remove free chlorine to avoid oxidation damage to filter media. Keep raw water temperature within standard operating range.
Q5: Is this filter cartridge fully interchangeable with original Pentair Aqualine housings?
A5: Yes. Dimensions, end cap sealing structure and installation interface are fully consistent with original Pentair Aqualine series, supporting direct plug-and-play installation without housing modification.
