What is a High Flow Filter Cartridge?

A high flow filter cartridge is a large-diameter pleated filter designed for high-volume liquid filtration, capable of handling up to 500 gallons per minute. Its pleated design increases filtration area and dirt holding capacity, offering long service life and lower operating costs. Media options include polypropylene (PP), polyester (PET), glass fiber (GF), and activated carbon.

What is the Production Process of a High Flow Filter Cartridge?

The production process includes pleating high-quality filter media, ultrasonic welding, trimming, and assembling with a strong PP or stainless steel core. End caps are thermally welded to ensure integrity, and longer filters are produced by welding shorter lengths together. This process ensures leak-free performance and durability under pressure.

What are the Key Features of a High Flow Filter Cartridge?

High flow cartridges provide high dirt-holding capacity, long service life, and flow rates up to 110 m³/h per element. Their inside-to-outside flow design captures contaminants securely, while thermal bond welding ensures no glue or leakage. They also require fewer housings, saving space and reducing system costs.

What Media is Used in High Flow Filter Cartridges?

Filter media options include polypropylene (PP) for standard water treatment, polyester (PET), and glass fiber (GF) for high-temperature applications. Activated carbon is also available for specialized needs. Each media type offers different benefits, making cartridges versatile across industries.

How Many Types of High Flow Filter Cartridges Are Available?

Pullner produces high flow cartridges compatible with brands like PALL, 3M CUNO, Parker, Pentair, and Graver, as well as customized models. Options also vary by filter media, with PP rated for 82℃, PET for 150℃, and GF for 250℃. This ensures suitability for a wide range of conditions.

How to Choose the Right High Flow Filter Cartridge?

Selection depends on application, required micron rating, fluid characteristics, and operating temperature. Customers can choose among media such as PP, PET, GF, or carbon, along with seals made of silicone, EPDM, Buna-N, or Viton. The right choice optimizes performance and cost-efficiency.

What is the Dirt Holding Capacity of a High Flow Filter?

Thanks to their pleated structure and larger surface area, high flow filters can capture significantly more dirt than standard cartridges. This reduces replacement frequency and labor, while also lowering total filtration costs. It makes them especially cost-effective in large-scale operations.

How Long is the Service Life of a High Flow Filter Cartridge?

High flow filters typically last longer than standard 2.7-inch pleated filters because of their larger diameter and filtration area. However, actual service life depends on liquid quality, flow conditions, and maintenance. Cleaner water extends service life, while dirtier water shortens it.

How to Determine the Service Life of a High Flow Filter Cartridge?

Service life is determined by theoretical lifespan, water quality, and equipment condition. Poor water quality or dirty equipment can shorten life, while cleaner systems extend it. Regular monitoring of pressure drop helps determine replacement timing.

What is the Micron Rating of a High Flow Filter Cartridge?

High flow cartridges are available in ratings from 1 to 100 microns. They come in both absolute ratings (98% efficiency) and nominal ratings (95% efficiency), suitable for various precision levels in filtration.

What are the Applications of High Flow Filter Cartridges?

Applications include seawater desalination, RO pre-filtration, power plant condensate treatment, and biopharmaceutical processing. They are also widely used in food and beverage, petrochemicals, coatings, microelectronics, and automotive industries. Their high flow rate and long service life make them ideal for large-scale systems.

How to Calculate the Filtration Area of a High Flow Filter Cartridge?

A 20-inch filter offers about 2.6–6.6 m² of filtration area, while a 60-inch filter can reach 10 m². Pleat count and media thickness affect total surface area. More pleats and thinner media create a larger effective filtration surface.

How to Install High Flow Filter Cartridges?

Installation involves wetting the O-ring, inserting the cartridge fully, tightening the pressure plate, venting air, and gradually opening valves. For cleaning, cartridges can be backwashed or rinsed with approved solutions like NaOH or citric acid. This ensures reliable sealing and extended use.

How to Get a Free Sample of High Flow Filter Cartridges?

What are the Filtration Performance Requirements of a High Flow Filter Cartridge?

Performance requirements include high filtration efficiency, good permeability, and strong dust-holding capacity. Materials must also provide durability, chemical stability, and cost-effectiveness. These qualities ensure reliable operation across demanding industrial applications.

What is a High Flow Filter Cartridge?

A high flow filter cartridge is a large-diameter (6″/152 mm) pleated liquid filter that handles up to 110 m³/hr (500 GPM) per element. The pleated design delivers 2.6–10 m² of filtration area per cartridge — replacing 90% fewer elements than standard 2.7″ filters and reducing housing footprint by 50%.

What Filtration Ratings Are Available for High Flow Filter Cartridges?

Pullner high flow filter cartridges are available from 1 µm to 100 µm: 1, 3, 5, 10, 15, 20, 40, 70, and 100 µm. Both absolute and nominal ratings are offered. Non-standard ratings are available on request — common for seawater desalination RO pre-filtration (5 µm) and power plant condensate (1–5 µm).

Which Brands Can Pullner High Flow Filter Cartridges Replace?

Pullner high flow filter cartridges are drop-in replacements for PALL Ultipleat and Marksman, 3M CUNO 740B and 7000 Series, Parker MegaFlow, Pentair Aqualine, and Graver high flow filters. Same outer diameter, O-ring configuration, and length — no housing changes required.

How Do I Choose the Right High Flow Filter Cartridge?

Three factors determine the right selection: (1) Media — PP for water and general liquids up to 82°C, PET for up to 150°C, Glass Fiber for petrochemical up to 250°C; (2) Micron rating — 1–5 µm for RO pre-filtration, 10–40 µm for general industrial; (3) Length — 20″, 40″, or 60″ based on your housing and required flow rate.
