PFHB High Pressure Full Flow Bi-Directional Filter Assemblies Specifications

PFHB High Pressure Full Flow Bi-Directional Filter Assemblies

Hy-Pro’s PFHB high pressure filter assemblies are designed for applications where flow direction changes and fluid must be filtered with full flow in both directions. Protect both components and clean fluid that typically does not return to the reservoir.

Ideal for steel mills, board plants, scrap yards, and concrete mixers.

Max Operating Pressure: 7252 psi (500 bar)
