Melt-Blown Poly Sediment filters are constructed with 4-layers of different micron ratings. The graded densities of layers capture particles throughout the entire cross section of the cartridge reducing surface binding or buildup.
That sediment buildup results in greater pressure drops and quicker replacement of the cartridge. The finer the particle the deeper through the surface of the cartridge it travels. Example: a 5 micron rated cartridge has these four layer densities - Inside Layer - 5 micron, 2nd Layer - 10 micron, 3rd Layer - 25 micron, Outer Layer - 50 micron.
These filters are made from 100% high purity polypropylene, have good chemical resistance are not prone to bacteria attack. It meets the NSF/ANSI Component Standard 42 .
We use this cartridge in our systems primarily for sediment removal.
