STAUFF pressure filters for line installation and control block mounting – also as top loader – are used as working filters or protective filters in the pressure line of hydraulic and lubrication systems with up to 420 bar (6,090 PSI) operating pressure. As working filters, they are placed downstream of the pump where they protect the entire hydraulic system against the impact of contamination. As a protective filter, they protect, for example, servo valves or proportional valves when installed directly upstream of these sensitive components.
