Backwashable High Flow PP Pleated Filter Cartridge for Water Treatment

General Description

The High Flow Pleated Filter Cartridge is designed for high-volume water filtration. It uses deep-pleated polypropylene (PP) or glass fiber media to deliver high flow, low pressure drop, and long service life.
With a 6" (152 mm) large diameter design, no center core, and a dedicated inside-to-outside flow direction, contaminants and particles are retained inside the cartridge, making maintenance more efficient and extending filtration cycles.
Its ultra-high flow capacity helps reduce the number of cartridges and housing size required, significantly lowering capital investment, installation space, and labor cost.

Key Features & Benefits

• High filtration area, high flow rate
Large effective filtration area provides low differential pressure and high throughput.

• High dirt-holding capacity, longer service life
Multi-layer gradient pore structure (deep media design) improves particle retention and dirt loading capacity, helping extend replacement intervals and reduce operating cost.

• Wide micron ratings and multiple lengths available
Micron ratings from 1 µm to 70 µm and lengths of 20" / 40" / 60" to match different filtration requirements.
