Flat and domed explosion vents

Cost-effective overpressure protection for low to medium vacuum conditions

Elfab’s multi-layered explosion vent range combines layers of stainless steel and fluoropolymer to create a high performance explosion venting solution.

Available as square, rectangular, round or trapezoid, with a wide range of bolt pattern configurations, the panels are all non-fragmenting. They are also suitable for high temperature applications with a standard burst pressure offering of 0.05 or 0.1 BarG @15/30°C with a 25% tolerance.

Elfab is unique in having its explosion vents approved as a ‘protective system’ II GD when used with an Elfab-approved frame).

Offering a low maintenance solution with a dust tight seal and excellent corrosion resistance, this flat non-fragmenting design is now a widely-used explosion protection solution for limited vacuum applications.

The domed design offers the highest operating ratio of all our explosion vents (80%). It therefore benefits from enhanced operating performance under cyclic pressure, back pressure and vacuum conditions.

Burst detection
Both flat and domed vents are compatible with Vent-Tel, our ATEX-approved burst detection system for explosion panels. Vent-Tel is a non-invasive, fail-safe burst detection system designed to ensure the safety of onsite personnel.

Existing explosion venting panel installations without a burst detection system can be retrofitted with the Vent-Tel system.
