Des-Case Hygroscopic line of air filter and water vapor removal breathers replace standard breather caps on hydraulic reservoirs, gearboxes, and process tanks. They prevent dirt and water contamination and extend service life of oils, filters, hydraulic fluids, and system components. Self-contained units use a desiccant to extract water vapor from air and micro-fiberglass pleated filters to remove particles down to 1 m.
