High-purity, finely fibrillated cellulose fibers form the support structure of Eaton’s depth filter sheets and provide a large internal surface. Different perlite qualities ensure a voluminous, asymmetric pore structure and thus a large dirt holding capacity. Conventional depth filter sheets with different clarifying sharpness and unfiltrate volume offer specifically tailored filtrate quality in all filtration ranges. Due to its structure, diatomite has very good filter characteristics. The quantity and type of the diatomite processed determines the clarifying sharpness and the throughput rate.

Cartridge filters can be the logical choice for a wide variety of applications with varied flow rates that require sub-micron retention rating, including food and beverage, chemicals, paint and the filtration of acids and bases. Cartridge filtration can also be an effective choice for pharmaceutical and ultra-pure water applications.

The individual cartridge cells are made up using BECOPAD depth filter sheets and the outer edge of two of these depth filters, whose outlet side is in contact with a drainage plate, is coated with polypropylene and sealed. Depending on the cartridge type, a different number of stacked filter cells forms a cartridge unit, which is safely held together by the three-part segmented sleeve made from stainless steel. Sealing between the filter cells is via accurately fitting intermediate profile rings. When installed, the segmented sleeve made from stainless steel ensures excellent mechanical sealing of the module. The occurrence of bypass effects is therefore eliminated.
