PFH High Pressure In-Line Filter Assemblies

Hy-Pro’s PFH14, PFH55, and PFH167 pressure filters are designed to protect sensitive components in hydraulic circuits. Install the series upstream of specific components or directly after the pressure pump in smaller systems to minimize risk of failure and costly system downtime.

Ideal for use as a power unit pump discharge filter or a pilot filter, and to protect components that are sensitive to particulate contamination and require clean pressurized fluid for reliable operation, such as servo valves.

Max Operating Pressure: 6090 psi (420 bar)
