About the Hy-Pro HP28NL7-1AV
Hy-Pro HP28NL7-1AV is a filter element rated at 1 µm (1 µm nominal), a beta ratio of β ≥ 1000, 450 psid collapse pressure, and measuring 2.36 in OD, 1.39 in ID, and 6.91 in length. It uses microglass (water removal) media and Viton (FKM) seals, rated for -20 °F to 250 °F (Hy-Pro datasheet).
Application & Compatibility
The HY-PRO HP28NL7-1AV is designed for use in hydraulic and lubrication filtration systems. With a 1µm rating, this element is suitable for servo valve protection and high-precision hydraulic systems. Viton (FKM) seals provide compatibility with petroleum-based fluids, synthetic fluids, phosphate esters, and water-glycol mixtures.
The 450 PSID collapse rating indicates the maximum differential pressure this element can withstand during cold starts or bypass conditions without structural failure. Ensure your system's maximum differential pressure does not exceed this rating.
