Inert Gas Pressure Vent SHX Range

If using an inert gas such as IG-55 or other nitrogen based gases then the SHX-UN One Way Pressure Vent is the vent to use.

The discharge of an inert gas into a room aims to add up to 50% volume to the air. If the room were hermetically sealed then this could theoretically produce pressure of around 50,000 pascals. In reality, in a room with natural leakage, the pressure would be nowhere near this level, but would still pose a serious risk of damage to the structure, especially in the first 0.25 to 2 seconds of discharge.

In order to greatly reduce the potential room overpressure, a fast acting, low pressure opening pressure vent should be installed.

The AmVentco SHX Inert Gas Pressure Vent has been specially designed to give the best pressure relief for its size in the world. It is still the only pressure vent that is built and certified to the AFP/LPG/BRE live discharge tests of 2008. Proving that it not only gives the best pressure venting operation among other vents, but also that this 3rd party verification testing offers real proof of its claimed operational capabilities.

Sizing of the vents for a risk should be derived and confirmed from either the gas supplier’s calculations or from an integrity test. However, for a rough estimate purpose, please refer to the following charts.
