The FSV range of Pressure Relief Vents are designed specifically for over-pressure venting associated with inert gas high pressure Fire Suppression Systems. The vents can also provide protection against under-pressure venting with synthetic gases such as FM200 and NOVEC 1230 when used in conjunction with our SGV range of vents.

The units are offered in a number of standard sizes for installation in both internal and external walls. Providing market leading performance across a range of pressures.The vents are designed to start opening at 80Pa and fully open at 100Pa, this allows annual integrity room tests to be performed without the need to block the vents during such a test.
