APL Series High Flow Filter Cartridge is a high-performance liquid filtration solution designed as a reliable replacement for Pall Ultipleat High Flow Water Filter Cartridge.

Designed with advanced pleated polypropylene filter media and a rigid polypropylene support cage, APL Series provides excellent filtration efficiency, high dirt-holding capacity, and stable performance under high flow operating conditions.

Compared with conventional sediment filter cartridges such as melt blown and string wound filters, APL high flow cartridges offer a much larger filtration area, higher flow capacity, and longer service life. They are widely used for industrial water filtration, RO system pre-filtration, seawater desalination, power generation, and process liquid filtration.

As a professional high flow filter cartridge manufacturer, AALFilter provides more than 50 types of high flow filter end connections, enabling direct replacement solutions for high flow cartridges from brands such as Pall, 3M, Parker, Pentair, and other major filtration suppliers.

What Is APL Series High Flow Filter Cartridge?

APL Series High Flow Filter Cartridge is designed for applications requiring high flow rates, high contaminant holding capacity, and reliable filtration performance.

The cartridge adopts a multi-layer pleated polypropylene filter media structure, combined with an internal support core and external protective cage. This optimized construction provides excellent mechanical strength and helps maintain stable filtration performance during long-term operation.

With an effective filtration area of up to 12 m², APL Series significantly reduces the number of filter cartridges required compared with traditional 2.5-inch filter cartridges, helping customers reduce equipment footprint, maintenance frequency, and operating costs.

The inside-to-out filtration design allows contaminants to be trapped inside the cartridge, protecting downstream equipment and reducing the risk of secondary contamination.

APL Series high flow filter cartridges are especially suitable for RO membrane pre-filtration, where stable particle removal performance is critical for extending RO membrane service life.

Key Features

1. Large Filtration Area · High Flow Capacity

The 6-inch large diameter design provides a significantly increased filtration area compared with conventional filter cartridges.

With filtration areas up to 12 m², APL Series delivers high flow capacity while maintaining low pressure drop, reducing the number of cartridges required in large-scale filtration systems.

2. Pall Ultipleat High Flow Filter Cartridge Replacement

APL Series is designed as a compatible replacement for Pall Ultipleat High Flow Water Filter Cartridge.

With multiple end connection options and customizable specifications, AALFilter can provide replacement cartridges according to different housing designs and operating requirements.

3. Multiple Pleated Layer Construction

The advanced multi-layer pleated polypropylene structure provides:

· Higher dirt-holding capacity

· Improved particle capture efficiency

· Longer service life

· Stable filtration performance under high flow conditions

The optimized media structure offers better protection for downstream systems compared with conventional melt blown and string wound sediment cartridges.

4. Strong Inner Core and Protective Outer Cage

APL Series features a reinforced inner support core and rigid outer cage.

This structure improves mechanical strength, prevents media deformation during operation, and allows the cartridge to withstand higher differential pressure conditions.

5. Inside-to-Out Flow Configuration

The inside-to-out filtration direction captures contaminants inside the cartridge.

Benefits include:

· Reduced risk of downstream contamination

· Better protection for sensitive equipment

· Improved filtration stability

6. Integrated Handle Design for Easy Replacement

The built-in top handle allows operators to quickly install and remove cartridges from the filter housing.

This design helps reduce maintenance time and improves operational safety.

7. FDA-Compliant Polypropylene Materials

All filter media and components are manufactured using polypropylene materials that comply with FDA requirements.

The safe material construction makes APL Series suitable for applications with strict material compatibility requirements.

8. Multiple Micron Ratings and Length Options

APL Series is available in various filtration ratings and cartridge lengths to meet different system requirements.

Customized specifications are available according to customer flow requirements and housing design.
