Pentair Aqualine ALN01‑60B Large‑Diameter High‑Flow Pleated Filter Cartridge
Introduction:If you are sourcing Pentair Aqualine ALN01‑60B high‑flow filter cartridge for large‑capacity industrial water treatment and RO pre‑filtration, this drop‑in replacement pleated filter adopts gradient polypropylene media for stable 1‑micron particle removal. It delivers enormous filter area, excellent dirt‑holding capacity and reliable high‑flow performance, capturing suspended solids, silt, rust and colloidal impurities inside raw water. Serving as critical pre‑treatment protection for RO and NF membrane systems, it effectively lowers membrane fouling probability and extends membrane service lifespan. Its 60‑inch extra‑long large‑diameter single open‑end design reduces total cartridge quantity inside filter housings. As cost‑effective alternative manufactured in China, it suits heavy‑duty water‑treatment projects for global EPC contractors and industrial end‑users.

Product Overview
Pentair Aqualine ALN01‑60B is a heavy‑duty 60‑inch large‑diameter high‑flow pleated filter cartridge, widely deployed for industrial raw‑water pre‑treatment, seawater desalination and municipal water‑supply projects. Nominal length reaches 60 inch (1524 mm), outer diameter 6.75 inch (171.5 mm). It is constructed with cross‑linked gradient polypropylene micro‑fiber filter media, nominal 1 μm filtration rating. Reinforced nylon end caps and rigid inner support core improve overall structural strength under high‑flow working conditions. Integrated molded lifting handle enables tool‑free quick replacement. Standard seal material is Buna‑N, EPDM and FKM are optional for different chemical liquid environments. Flow direction is outside‑to‑inside, perfectly matches mainstream large‑flow filter housings without mechanical modification. Thermal welding technology eliminates adhesive, avoiding secondary contamination risk. This interchangeable filter element is extensively applied in seawater desalination RO pre‑filtration, power plant boiler feed‑water, petrochemical process water, municipal waterworks and large‑scale ion‑exchange resin protection systems.
Working Principle
Pentair Aqualine ALN01‑60B high‑flow filter cartridge works with outside‑to‑inside flow path. Untreated raw water flows radially into the cartridge from outer pleated surface. Large‑sized impurities including silt, rust particles and suspended solids are trapped on outer pleated layers. Medium and fine particles are gradually intercepted by depth‑filtration effect within multi‑layer gradient polypropylene media. Large pleated surface slows down blocking speed and maximizes dirt‑holding capacity. After purification, qualified water flows inward through central support core and discharges from single open‑end outlet. Precision O‑ring seal prevents bypass of unfiltered fluid, ensuring all incoming liquid passes through filter media and maintains stable 1 μm filtration performance. As first‑stage security pre‑filter, it greatly reduces impurity load for downstream RO, NF membrane and ion‑exchange equipment.
Core Technical Specifications
Core Advantages
Gradient‑pore 1μm depth filtration:
Cross‑linked polypropylene micro‑fiber media provides stable particle interception performance, offers reliable pre‑treatment protection for reverse osmosis and nanofiltration membrane systems.
60‑inch extra‑large dimension design:
Super‑large effective filtration area brings outstanding dirt‑holding capacity, extends service cycle, reduces cartridge consumption and cuts down frequent‑replacement maintenance workload.
Strong chemical compatibility:
Polypropylene wetted components keep stable performance for water‑based fluid, weak acid and weak alkali working conditions. Optional FKM seal adapts to special corrosive liquid.
Tool‑free quick‑change structure:
Built‑in lifting handle simplifies on‑site replacement operation; standard dimension fits most existing large‑flow filter housings, no housing modification required.
Economical domestic replacement solution:
Manufactured by Chinese filter factory. It realizes equivalent overall performance compared with original spare parts, helping global industrial clients and engineering contractors control total project procurement cost.
Main Application Scenarios
Reverse osmosis pre‑filtration for seawater desalination and industrial water‑treatment plants
Power plant boiler feed‑water and condensate‑water purification
Petrochemical and fine chemical process liquid pre‑filtration
Large‑scale municipal water‑supply pretreatment system
Ion‑exchange resin protection filtration for water‑treatment workshops
Large‑size mining circulating water pre‑treatment
FAQ
Q1: Can Pentair Aqualine ALN01‑60B fit my existing filter housing?
A1: It features 60‑inch length, 6.75‑inch outer diameter and single open‑end outside‑to‑inside flow structure. Please check the inner dimension of your filter housing before purchase; most mainstream large‑flow housings support direct installation.
Q2: When do I need to replace ALN01‑60B filter cartridge?
A2: Carry out replacement when differential pressure rises to 1.7‑2.1 bar (25‑30 PSID). Actual service life is highly related to raw water impurity concentration.
Q3: What is the maximum operating temperature for this filter element?
A3: Max continuous operating temperature is 54.4℃. Long‑time operation beyond this temperature will cause polypropylene media deformation and reduce filtration efficiency.
Q4: Are other micron grades available for this Aqualine series?
A4: The series supplies multiple specifications:1 μm,5 μm,10 μm,20 μm,40 μm,70 μm,100 μm. Custom‑made options are available for bulk‑order projects.
Q5: What is the production lead‑time for bulk ALN01‑60B orders?
A5: For standard‑spec filter cartridges, lead‑time is 7‑15 working days upon deposit confirmation. Customized requirements need extra production cycle.
