    The FSV-F Ceiling-mounted range of inert gas vents is 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 Vent is offered in two standard sizes for horizontal (ceiling) installation. 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.

     

  • Apreco inert gas vent

    Demand for Apreco’s inert gas vent is increasing with the recognised need for over and under pressure venting associated with Inert and Synthetic Gaseous Fire Suppression Systems.

    Buildings are most commonly designed to withstand internal pressures of between 250 to 500Pa, though this can vary depending on the type of construction. The use of correctly sized and functioning pressure relief vents will protect such building structures from damage.

    Apreco inert gas vents are of ‘counter-weighted’ design to prevent the risks of over and under pressurisation resulting from the use of gas fire suppression systems. The Apreco range of pressure relief vents have been successfully tested to EN1364-1 criteria to provide a 4-hour fire resistance rating.

    Specifically developed for these applications, the range can be used alongside a wide range of gas fire suppression systems to prevent structural damage and risk to personnel.

    Maximum room pressure is controlled by the vents opening to allow air to escape, then closing when discharge is complete. This maintains the dilution of the air, so preventing re-ignition.
