The Ayater UT319 series is a high-performance in-tank filtration solution designed for modern hydraulic systems that demand extreme fluid cleanliness. As a premium replacement for SRT-style tank-mounted filters, the UT319 series is engineered to handle massive return flows while minimizing aeration and pressure drop. By utilizing proprietary Stress-Resistant Technology (SRT), these elements maintain their efficiency even under rapid flow fluctuations, ensuring your system consistently meets ISO 4406 cleanliness
The UT319 is specifically designed for top-mounting on hydraulic reservoirs. Below are the comprehensive specifications for the Ayater UT319 replacement series:

Anti-Static Media Technology: The UT319 filter utilizes conductive layers to dissipate static charges generated by high-velocity oil flow. This prevents electrostatic discharge (ESD), which is a major cause of varnish formation and oil degradation.
In-to-Out Contaminant Retention: The unique flow direction ensures that all captured debris is contained within the element. During maintenance, contaminants are removed with the element, preventing "dirt rain" from falling back into the hydraulic tank.
Space-Saving In-Tank Design: By mounting directly inside the reservoir, the UT319 reduces the external footprint of the hydraulic power unit (HPU) while providing easy access for element changes.
Exceptional Beta Stability: Unlike conventional filters, Ayater's SRT media maintains its filtration ratio throughout the entire life of the element, even during cold starts and high-flow surges.
