MAXI-DEPTH, MAXI-WIND, HI-PERF, PUREFYBE and VALUWOUND filter cartridges offer true depth filtration. Wound cartridges are manufactured to provide selective particle retention throughout the media's depth which translates to high solids retention and longer service life with relatively low pressure drop. For nominal particle retention of .5 to 100 micron. Wound of cotton, polypropylene or mod-acrylic. Consult Application Engineering Department for glass, nylon, Orlon® and other fibers.

   POLYSPUN melt bonded filter cartridges are manufactured from continuous fibers thermally bonded and spun over a heated mandrel. Controlled graded density construction provides true depth filtration. These cartridges are free of resins, lubricants and anti-static agents; they are non-migrating and suitable for high purity applications.

    POLYSERF pleated filter cartridges are manufactured of continuous polypropylene microfibers self-bonded by a unique process that controls media uniformity and density. They provide large surface area for efficient particle removal with very low pressure drops. These cartridges are also free of resins, binders or surfactants for high purity applications. For nominal or absolute particle retention of .1 to 100 micron. Available double open end or with 222 "O"-ring seal.

    For use with filter aid or filter aid with carbon. Permits backwashing of chamber. May be individually cleaned and reused. Constructed of pleated polypropylene, wire mesh, sintered metal, ceramic or polypropylene sleeve.

   Sleeve-type filter cartridges may be used uncoated or precoated with filter aid. Sleeve cartridges are interchangeable with any regular cartridge of corresponding length. Sleeves don't have the solids holding capacity of cartridges, so they require frequent cleaning. However, this makes sleeves re-usable for economical operation and, therefore, minimizes disposal costs.

    For adsorption of soluble impurities when using powdered or granular cartridges or refillable canisters for granular carbon.
