3M Betafine XL Series Filter Cartridge, XL20PP025B0C, 20 in, 2.5 µ, 15/Case

3M Betafine XL Series Filter Cartridge is manufactured using a staggered pleat configuration, when combined with a novel support material, provides more open space between the pleats. The service life of our pleated cartridge is often dictated by the accessible surface area. Conventional 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 resulting in both flow restrictions and limited contaminant holding capacity. The ‘blind’ or unusable area commonly occurs near the inside diameter where the pleats are packed most tightly.
