The absolute rated Betafine XL filter cartridge series is made of a 100% polypropylene pleated filter featuring advanced pleat technology (APT). This product is appropriate for use in a wide range of applications, including - food and beverage, industrial and electronics.. The Betafine XL series filter cartridge features 100% polypropylene construction that provides chemical and thermal compatibility in many demanding process fluid applications. The filter media is constructed from continuous micro-fibers that provide a uniform matrix. There are nine distinct absolute rated filter grades, beginning at 70 microns, ranging to the very fine 0.2 micron rating. The betaine XL filters are absolute rated to Beta 1000 (99.9% efficiency at each respective rating). Additionally, filters come in a range of integral lengths from 9 and frac34; to 40 inches with a wide selection of end treatments to fit common filter housing designs. Advanced pleat technology (APT)Pleated filters may offer a large gross surface area, but when the media is packed too tightly into the cartridge, only part of the surface area is usable and resulting in both flow restrictions and limited contaminant holding capacity. The and blind; or unusable area commonly occurs near the inside diameter, where the pleats are packed most tightly. The Betafine XL filter cartridge features an advanced pleat technology (APT) design for extended service life. This design maximizes the useful surface area while maintaining open flow paths between media pleats. Typical Applications - machine tool lubrication, detergents, process and waste water reverse osmosis (RO) protection and pre-filtration solvent, bulk chemical and process filtration.
