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)

Dynamic Filter Efficiency

Hydraulic applications see dynamic flow changes on a regular basis. Dynamic Filter Efficiency testing takes the ISO16889 Multi-Pass testing even further with variable flow shifts to ensure your filter elements stand up to real world conditions and maintain the highest capture and retention rates in the industry.

Industrial duty.

Standard mounting holes for optional brackets, aluminum ID tags, a variety of indicator options, and standard drain ports make the PFH the ideal choice for heavy duty hydraulic filtration.



Unique applications.

With available nickel plating, the PFH14, PFH55 and PFH167 are ideal choices for rough duty, high water contamination applications. Media options include wire mesh, water removal, and Dualglass to address even the most unique contamination. A reverse flow check valve option enables usage in reversing hydrostatic drive systems.

Minimize the mess.

The PFH series comes standard with bowl drains to minimize mess during servicing. The circumferential o-ring bowl seal eliminates leaking and weeping.

Extend the life of your element.

Unique internal flow paths provide low resistance to flow, resulting in a low housing pressure drop. Hy-Pro’s advanced filter media delivers lower operating ISO Codes to eliminate internally generated contamination meaning your filter will have an incredibly long service life to protect your sensitive components better than ever.

The ideal choice for hydraulics.

Use the PFH as the main high pressure filter(s) in a hydraulic system or upstream of sensitive components as a pilot filter to protect your valves and actuators. The PFH series is engineered to provide lower operating ISO Codes than what is required for compliance with hydraulic component manufacturers’ warranties.
