PI4205-010 *E77680325
For use in hydraulic systems, lubrication systems and test benches, we developed a wide range of efficient pressure filters that permanently ensure compliance with the purity classes of fluids and oils.
Nominal size to 450
- Low space requirement due to compact design
- Minimum pressure drop due to streamlined design of components
- NPT and SAE threaded connections available

For hydraulic systems and lubrication systems, we have a comprehensive range of high-pressure filters in our product portfolio. These are available in various designs and dimensions and for different pressure ratings. A cold start valve can be integrated in the filter head of the Pi 420. It ensures that only filtered fluid is supplied to the hydraulic system in all operatingstates.
If the differential pressure rises above the opening pressure of the cold start valve (e.g. due to excessive viscosity of the fluid during a cold start or if the element has not been changed), a partial flow is returned to the hydraulic tank via the tank connection on the filter head. The robust housing can withstand even strong operating pressure, while the streamlined designs also ensure maximum performance.
