Pentair Aqualine Aln01‑60b Water Filter Element 1 Micron High‑Flow Pleated Cartridge

Pentair Aqualine Aln01‑60b Water Filter Element 1 Micron High‑Flow Pleated Cartridge

Pentair Aqualine Aln01‑60b Water Filter Element is a nominal 1‑micron single open‑end high‑flow pleated cartridge, engineered for Aqualine‑series FRP horizontal filter housings and widely adopted as critical security pre‑filtration consumable for industrial reverse osmosis systems. It works alongside POV12UNPFA high flow filter cartridge, and cooperates with PFTM102UEPFA high flow filter cartridge to deliver precise fine‑particle interception for seawater desalination, power‑plant boiler makeup water and industrial water reuse projects. Pentair Aqualine Aln01‑60b Water Filter Element adopts proprietary cross‑linked PolyForm locked‑pore gradient polypropylene pleated media, featuring 60‑inch length, 6.75‑inch outer diameter, large dirt‑holding capacity and low initial differential pressure. It effectively traps ultra‑fine silt, suspended solids and tiny colloidal contaminants, minimizing particle scratch and premature fouling risks for high‑cost downstream RO membrane modules. Equipped with integrated molded lifting handle and standard Buna‑N single O‑ring sealing interface, ALN01‑60B supports tool‑free quick cartridge swap, reducing equipment downtime and long‑term O&M expenditure for global industrial water‑treatment sites.

Product Description

Pentair Aqualine Aln01‑60b Water Filter Element is the 1‑micron flagship model of Pentair Aqualine high‑flow cartridge series, designed for heavy‑duty large‑volume liquid pre‑filtration and RO guard filtration conditions. Standard dimension is 60‑inch (1524 mm) nominal length and 6.75‑inch (171.5 mm) outer diameter, adopting single open‑end (SOE) outside‑in flow configuration, eliminating auxiliary parts like springs and guide posts required by conventional small‑diameter filter cartridges.

The whole filter element adopts full polypropylene construction, including cross‑linked gradient PolyForm pleated filter media, reinforced polypropylene inner‑outer support cages, injection‑molded nylon end caps, rigid PVC central core and Buna‑N O‑ring gasket as standard sealing component. All bonding joints are finished by thermal fusion welding without adhesive addition, eliminating secondary fluid‑contamination risks caused by glue dissolution. Deep‑pleated media structure greatly expands effective filtration surface area, delivering outstanding single‑element flow capacity compared with traditional filter cartridges. Its nominal filtration rating is 1 micron, dedicated to removing ultra‑fine silt, fine suspended particles and tiny colloidal substances ahead of high‑precision RO membrane systems.

Integral molded lifting handle is built on the open‑end side, simplifying pulling‑out and installation operations during on‑site maintenance. ALN01‑60B can be directly installed into original Pentair Aqualine FRP horizontal filter housings without mechanical modification. When cooperating with upstream multimedia filtration and activated carbon treatment equipment, the system can stably maintain feed‑water SDI value below 5, satisfying strict inlet‑water technical requirements of seawater and brackish‑water reverse osmosis systems. This filter element is heavily purchased by EPC contractors, water‑treatment plant operators and spare‑part distributors for new project commissioning and routine spare‑part inventory. Standard maximum continuous operating temperature reaches 54.4 °C (130 °F); customized high‑temperature resistant versions can meet higher‑temperature working‑condition demands on request.

Working Principle

Pentair Aqualine Aln01‑60b Water Filter Element operates based on outside‑in cross‑flow depth microfiltration principle. Untreated raw water flows into sealed Aqualine‑series FRP filter housing and evenly distributes toward the outer pleated surface of ALN01‑60B cartridge. Driven by system operating pressure, large‑particle sediment and coarse suspended flocs are trapped on outer pleated layers, while ultra‑fine particles and tiny colloids are intercepted layer‑by‑layer through gradient cross‑linked polypropylene media from outer surface to inner core.

Purified filtrate penetrates filter media layers, converges inside rigid PVC central core and flows out toward downstream RO or UF membrane units. The gradient pore structure realizes outer‑coarse‑inner‑fine depth filtration, maximizing dirt‑holding capacity and slowing the rising speed of inlet‑outlet differential pressure. With continuous system running, intercepted pollutants keep accumulating on filter media surface. Operators must replace ALN01‑60B cartridges timely when differential pressure reaches 25‑30 PSID alarm threshold, so as to restore rated water throughput and filtration performance.

All‑polypropylene material provides good chemical compatibility, tolerating most neutral aqueous solutions and conventional acid‑base cleaning agents for filter housing routine maintenance. Reinforced inner‑outer support cages effectively prevent media collapse and deformation under high‑velocity water‑flow impact, avoid fluid bypass phenomenon, and guarantee stable 1‑micron particle‑removal efficiency throughout the whole service cycle.
