Product Description
Pentair Aqualine High Flow Cartridge Filter represents the core high‑flow product line of Pentair filtration division, covering widely‑used part numbers ALN01‑60B, ALN05‑60B, ALN10‑60B, ALN20‑60B and more. The standard physical dimension is 60‑inch length and 6.75‑inch outer diameter, single open‑end configuration purpose‑built for high‑volume industrial water treatment scenarios. The whole cartridge adopts full polypropylene construction, consisting of reinforced inner and outer support cages, cross‑linked gradient pleated polypropylene media, injection‑molded reinforced end caps, rigid PVC central core and high‑performance elastomer O‑ring gaskets.
Every bonding position of the filter cartridge is completed by thermal fusion welding process without any adhesive addition, thoroughly eliminating the risk of secondary water contamination caused by glue dissolution. The special deep‑pleated structural design greatly enlarges the effective filtration area per single cartridge, realizing extremely high single‑element flux, which can sharply cut the total quantity of filter cartridges and the overall volume of filter housings required by the water treatment system. Multiple micron ratings from 1 μm to 90 μm are available, covering coarse pre‑filtration and fine security filtration for diversified raw water quality conditions.
Following the classic outside‑in flow principle, most contaminants are trapped on the outer layers of pleated media to reduce the risk of fine impurity leakage toward downstream pipelines. When matched with upstream multimedia filtration and activated carbon devices, this high‑flow cartridge can stably control feed‑water SDI value below 5, satisfying strict inlet water standards of seawater and brackish water reverse osmosis systems. Multiple cartridges can be arranged in parallel inside Aqualine‑style horizontal filter housings to handle large‑capacity water input. This series is extensively adopted in seawater desalination pretreatment, boiler makeup water treatment, petrochemical process liquid purification, electronic ultrapure water manufacturing and industrial wastewater recycling. Both EPC contractors and end‑site operators select Pentair Aqualine High Flow Cartridge Filter for new skid‑mounted projects and daily spare‑part replenishment.
Working Principle
Pentair Aqualine High Flow Cartridge Filter applies outside‑in cross‑flow microfiltration working mechanism. Untreated industrial raw water flows into the sealed FRP filter housing and evenly distributes to the outer surface of pleated filter media. Under water pressure driving force, large‑particle sediment, suspended flocs and coarse impurities are intercepted on the outer pleated layers, while tiny colloids and fine particles are gradually trapped by the inner gradient polypropylene media layer by layer.
Purified filtrate penetrates filter media layers, converges inside the rigid PVC central core, and flows out to enter subsequent membrane treatment units. The gradient hierarchical media structure achieves outer‑coarse‑inner‑fine depth filtration, significantly improving dirt‑holding capacity and slowing the rising speed of inlet‑outlet differential pressure. Along with continuous system running, intercepted pollutants keep accumulating on filter media. Operators need to implement cartridge replacement once pressure difference reaches 25‑30 PSID alarm threshold, so as to restore rated water throughput and filtration efficiency.
All‑polypropylene material offers good chemical compatibility, tolerating most neutral aqueous solutions and conventional acid‑base cleaning agents for housing routine maintenance. Thickened inner‑outer reinforced support cages effectively resist expansion and deformation under high‑speed water flow impact, prevent fluid bypass phenomenon, and guarantee stable particle interception performance throughout the whole service cycle. Standard continuous operating temperature for original‑spec cartridges is 54.4 °C (130 °F).

FAQ
Q1: What core models belong to Pentair Aqualine High Flow Cartridge Filter series?
A1: Core mainstream models include ALN01‑60B (1 μm), ALN05‑60B (5 μm), ALN10‑60B (10 μm), ALN20‑60B (20 μm). Users can select proper micron rating according to raw water quality and membrane system technical requirements.
Q2: Can Pentair Aqualine High Flow Cartridge Filter be cleaned and reused after fouling?
A2: Pentair Aqualine pleated polypropylene cartridges are disposable filter elements. Conventional chemical cleaning cannot restore original flux and accuracy after heavy contamination. Replace cartridges when differential pressure hits 25‑30 PSID alarm point.
Q3: What is the maximum continuous operating temperature of standard Aqualine high flow cartridges?
A3: Standard all‑polypropylene Aqualine cartridges support continuous operating temperature up to 54.4 °C (130 °F). Custom high‑temperature resistant versions are available for special working‑condition projects.
Q4: What feed‑water requirements are recommended when applying Aqualine cartridges for RO security filtration?
A4: It is recommended to keep feed‑water SDI ≤5, remove free chlorine and strong oxidants to prevent oxidation damage to polypropylene media, and keep water temperature within the standard operating range.
Q5: Are aftermarket replacement cartridges fully interchangeable with original Pentair Aqualine filter housings?
A5: Yes. Overall dimension, end‑cap structure, O‑ring position and installation interface are fully consistent with original Aqualine series, supporting direct plug‑and‑play installation without housing modification.
