Application & Compatibility
The INTERNORMEN 321591 is designed for use in hydraulic and lubrication filtration systems. With a 100µm rating, this element is suitable for pump and component protection in industrial hydraulic circuits. VITON seals provide compatibility with petroleum-based fluids, synthetic fluids, phosphate esters, and water-glycol mixtures.
The 435 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.
