These filters are connected to the pressure line to protect the system's components against contaminant particles. The standard filters are fitted with a bypass valve calibrated at 6 bar. For applications which need maximum protection of the system, such as servo and proportional controls, the filters are equiped with highly resistant filtering elements ("HC version" - high collapse pressure) and are not fitted with a bypass. Maximum working pressure: 420 bar Filter elements rated Beta 200 (99.5% efficiency)
