Application & Compatibility
The DONALDSON P171538 is designed for use in hydraulic and lubrication filtration systems. With a 23µm rating, this element is suitable for pump and component protection in industrial hydraulic circuits.
The 145 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.
