About the Hy-Pro HP311L15-40MB
Hy-Pro HP311L15-40MB is a filter element rated at 40 µm (40 µm nominal), a beta ratio of β ≥ 1000, 3000 psid collapse pressure, and measuring 3.63 in OD, 1.95 in ID, and 14.94 in length. It uses microglass media and Nitrile (Buna-N) seals, rated for -45 °F to 225 °F (Hy-Pro datasheet).
Application & Compatibility
The HY-PRO HP311L15-40MB is designed for use in hydraulic and lubrication filtration systems. With a 40µm rating, this element is suitable for pump and component protection in industrial hydraulic circuits. Nitrile (Buna-N) seals provide compatibility with standard petroleum-based fluids and mineral oils.
The 3000 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.
