25 Micron 20" Giant String Wound Cartridge

For a wide range of filtering applications, manufactured from FDA grade polypropylene. These cartridges are very suitable for potable water filtration. Ideal for removing very fine sediment right through to very coarse sediment, at ambient temperatures.

The cartridge is made by diagonally winding a precise pattern of carefully selected fibers on a centre core. The pattern is designed to create hundreds of identical, tapered, spiral passageways. During the winding, fibers are combed across the passage and locked in place by succeeding layers. Solid particles are removed by entrapment in this highly efficient filter media. Filtration takes place throughout the entire cartridge, not just on the surface, so large amounts of contaminant are trapped without a sudden rise in pressure caused by surface blinding. By varying the wind pattern, cartridges are fabricated to give a pre-determined micrometre rating.

• Gradient four (4) layer (outside-in), varied micron rate filter structure to capture particles (from larger to smaller) effectively and prolong cartridge life. Cartridge can achieve up to two times that of the double layers.
• 100% high purity polypropylene which is surfactant free, binder free and adhesive free.
• Good chemical resistance and is not prone to bacterial attack.
• Max Temperature Rating: 120°F (49°C)
• Maximum pressure drop: 80 psi
• Materials of construction: 100% melt-blown micron-denier polypropylene fiber.
• NSF/ANSI Standard 42 Certified
