About the Hy-Pro HP306NL3-25AV
Hy-Pro HP306NL3-25AV is a filter element rated at 22 µm (25 µm nominal), a beta ratio of β ≥ 4000, 450 psid collapse pressure, and measuring 2.165 in OD, 1.123 in ID, and 2.68 in length. It uses Dualglass + Water Removal media and Fluorocarbon (Viton) seals, rated for -20 °F to 250 °F (Donaldson Hy-Pro HP101 Data Sheet FE-101-071724, p.4).
Application & Compatibility
The HY-PRO HP306NL3-25AV is designed for use in hydraulic and lubrication filtration systems. With a 25µm nominal (β-rated, absolute 22µm) rating, this element is suitable for pump and component protection in industrial hydraulic circuits. Fluorocarbon (Viton) 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.
