Hydraulic filtration and accessories maintain valves, pumps, and motors in hydraulic systems. Filters remove contaminants in hydraulic fluid. They come in return line, suction, and pressure filter types. Return line filters are placed in a hydraulic circuit’s return line to filter hydraulic fluid. Suction filters have large filter housings, which allow them to filter heavy contaminants. Pressure filters are used to protect against pump failure. Filtration accessories support filters and include clogging indicators and breathers. Clogging indicators measure particle accumulation in filters. Breathers keep airborne moisture and contaminants out of hydraulic circuits.
