Elfab Pure-Gard
Sanitary Pressure Relief
Pure-Gard is an innovative, sanitary pressure relief solution specifically designed for applications where cleanability is of paramount importance. The new disc design provides a cleanable, robust solution to address the challenges of complex manufacturing environments including pharmaceutical, biopharmaceutical and food.
Crevice and dimple free design
Pure-Gard meets industry expectations for cleanability with its crevice and dimple free design. Our rigorous testing program includes dye penetrate testing and helium leak testing.
Structural stability
The one-piece design protects the rupture disc, avoiding the risk of damage at the point of installation. Pure-Gard’s structural stability also means its performance is unaffected by vent-side pipework loads.
Extended product life
Pure-Gard provides a solution independent of the gasket, allowing regular change of gaskets without needing to change the disc. This innovative design feature extends the life of Pure-Gard beyond conventional sanitary pressure relief solutions.
Pure-Gard SoLo
Pure-Gard SoLo is a low pressure variant suitable for use in processes where pressures are as low as 5 psig.
Reusable modular detection
Pure-Gard and Pure-Gard SoLo are designed for use with our Vent-Tel burst detection system, which is an independent, reusable and non-invasive solution. The Vent-Tel is mounted directly to the Tri-Clamp,making disc inspection and replacement quick and simple.
