What is a high flow filter?

A high flow filter cartridge is a pleated filtration element with a larger diameter than standard cartridges, designed to handle high flow rates (up to 500 GPM per cartridge) while using fewer filter elements overall. This reduces housing size, lowers labor and replacement costs, and increases filtration efficiency, making it a preferred choice for industries like seawater desalination, power plants, biopharmaceuticals, and food and beverage processing. Brother Filtration manufactures high flow filter cartridges built with a PP inner core, protective mesh, non-woven fabric, and filter membranes, offering durability, low pressure loss, and long service life across a range of micron ratings and housing configurations.

Brother Filtration is regarded as high flow filtration expert, will introduce everything about a high flow filter and help you figure out whether you need a high flow filter. If you want to have the knowledge about this kind of filter cartridge, please read the following article patiently.

What is the high flow filter cartridge?

High flow filter means the use of a smaller number of filter elements, reducing labor and operating costs. The high flow filter elements produced by Brother Filtration are durable with high efficiency, low-pressure loss, and long service time.

High flow filter, known as high flow water filter element, high flow filter element, high flow pleated filter element, etc.

It usually adopts PP inner core and outer skeletons, and the filter layer is made of protective mesh, non-woven fabrics, filter membranes, and other materials. The composition can be adapted to various water treatment conditions.

The larger diameter design of the high flow filter cartridge increases the effective filtration surface, which can greatly reduce the number of filter cartridges and reduce the size of the housing.

Designed for a variety of filter housings, these filter housings can hold 1 to 37 filter cartridges, which can be used for different flow requirements. Besides the outstanding advantages and abilities, those high flow filter cartridges have a more competitive price when compared to other brands.

Structure characteristics of high flow filter cartridges

• Higher operatinge The combination of surface filtration and depth filtration can greatly reduce the number of filter cartridges compared with conventional way
• Significantly reduce the size of the filter housing, and decrease the frequency of filter cartridge replacements and unnecessary losses during use, and improve efficiency.
• Longer service life and lower production costs—The pleated design increases the filter surface and makes the pressure drop significantly lower than the traditional filter cartridge;
• Easy to Install. The convenient handle design significantly shorten the time to replace the filter cartridge, making the replacement of the filter cartridge simple and easy.

For the design of high flow filter housing

An appropriate design for high flow filter housing can effectively reduce the installation footprint. Here, in Brother Filtration, two different types of high flow filter housing are provided for you.

The horizontal high flow FRP housing can simplify the operation, while the vertical high flow FRP filter housing can minimize the footprint of the system.

More than these, the combination of filter housing for high flow filter cartridge is also available for customer, which is the high flow FRP skid. By using this skid, all the benefits of high flow filter can be enlarged.

Thanks to the flow rate up to 500gpm in a single filter cartridge, fewer components are required. When combined in the skid, more advantages can have.

FAQ

1. How is a high flow filter cartridge different from a standard filter cartridge?

High flow cartridges have a larger diameter and more pleated surface area, allowing them to handle much higher flow rates (up to 500 GPM) per cartridge compared to standard filters, which need more units to achieve the same output.

2. What micron ratings are available for high flow filter cartridges?

Common micron ratings range from 1μm to 100μm (1, 5, 10, 15, 20, 40, 70, and 100 microns), allowing selection based on the required filtration precision.

3. How long do high flow filter cartridges last?

Service life depends on water quality and operating conditions, but the pleated design and larger filtration surface generally give them a longer lifespan than standard cartridges, reducing replacement frequency.

4. What industries use high flow filter cartridges?

They’re widely used in seawater desalination, power plant condensate systems, biopharmaceutical manufacturing, food and beverage production (bottled water, juice, milk, edible oil), paint and coatings, petrochemicals, and microelectronics.

5. What materials are high flow filter cartridges made from?

Typically polypropylene (PP) for the inner core and outer cage, with filter layers made from protective mesh, non-woven fabric, and filter membranes; gaskets are available in EPDM, silicone, Viton, or Buna-N.

6. What sizes do high flow filter cartridges come in?

Standard lengths are 20″, 40″, and 60″ (roughly 51cm, 102cm, and 152cm) with a 7-inch outer diameter, though custom sizing is available depending on the manufacturer.
