Pilot filters are an integral part of an underground Powered Roof Support (PRS) System. The ensure the hydraulic functions are on demand when required and stop contamination getting into your solenoid values. 

Our pilot filters are manufactured to the Australian Standard.

Test in Accordance with MDG41 Section 3.4.2.

3.4.2. Rated working pressure 

To avoid pressuirsed fluids escaping into the environment, fluid power system components should have appropriate factors of safety on the rated working pressure to bursting pressure. 

Hose assemblies should have a safety factor of at least 4:1 

Adaptor fittings should have a factor of safety of at least 4:1 on rated working pressure to catastrophic failure of the adaptor fitting  

Other fluid power components, such as cylinders, valves, actuators or similar should have a factor of safety of at least 2.5:1
