PRAB paper bed filters extend coolant and tool life, increase surface finish an average of 27% and control bacteria contamination. Standard paper bed filtration units handle flowrates of up to 130 gpm with different classes of filter media available to achieve specific micron clarity. Filters are suitable for applications of low- to medium-stock removal of ferrous and non-ferrous metals, as well as organic and inorganic contaminants, such as glass, rubber and plastic. Drum-type models occupy one-third the floor space and can process up to 500 gpm of fluids. PRAB’s Magnetic Paper Bed Filter models are ideal for pre-filtering ferrous materials from industrial process liquids. The filtering surface of a magnetic paper bed filter is automatically indexed only when necessary. Standard units are available with flow rates of up to 250 gpm (946 lpm) with an automated self-cleaning system that minimizes maintenance.
