Application & Compatibility
The DONALDSON P581845 is designed for use in hydraulic and lubrication filtration systems. With a 4µm rating, this element is suitable for servo valve protection and high-precision hydraulic systems.
The 149 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.
