Product Introduction
This industrial high flow filter cartridge is installed inside a large-flow water filter housing to capture suspended particles, colloidal impurities and fine contaminants. It can be used together with a self-cleaning filter or pre-filter to build multi-stage protection for critical industrial water systems. The PALL HFU640GF020H13 equivalent cartridge is a 40-inch high flow pleated filter element with 2.0μm absolute glass fiber media and EPDM (H13) seals. Compared with standard polypropylene elements, the glass fiber media offers higher rigidity and better stability under elevated temperature and differential pressure conditions. The equivalent replacement cartridge maintains the same overall dimensions, end connection style, inside-to-outside flow path and sealing interface. It can be installed into the existing filter housing without modification, helping users reduce procurement cost and shorten spare part delivery time while maintaining stable fine filtration performance.
Working Principle
The equivalent PALL HFU640GF020H13 cartridge uses inside-to-outside flow construction. Raw water or industrial liquid first enters the inner flow area of the cartridge, then passes outward through the pleated glass fiber media. Fine particles, suspended solids and colloidal impurities are trapped inside the progressive pore structure of the filter media, while clarified liquid flows out from the outer surface of the cartridge into the downstream system.
The glass fiber media provides high capture efficiency for fine particulate and colloidal impurities. When used with an upstream self-cleaning filter, larger particulate loads are removed in advance, helping stabilize differential pressure and extend cartridge service life.
