HT XPNF 31

Summary

Product identification

The TurboClean® High Temp XPNF Series elements, from MANN+HUMMEL Water & Fluid Solutions, are designed for continuous operation at temperatures up to 80°C. They feature a patented sanitary hard-shell design, offering improved system performance with approximately 60% less bypass flow compared to other sanitary elements. These elements are robust, capable of withstanding higher pressure drops, and designed for easy loading and unloading due to tight OD tolerance and optimal circularity.
