Under normal operation, the flame element allows the bi-directional flow of air and flammable vapour, however, it introduces additional pressure loss, and this must be considered in the design of the system. If a fire or ignition occurs external to the equipment and ignites the flammable discharge, the flame arrestor will quench the leading fire by absorbing and dispersing the heat as it passes through the element.
The unit is supplied with an earth point, copper tag, and cable. Periodically the cell can be removed for cleaning or replacement.
The Model 300 deflagration flame arrestor is suitable for quenching subsonic flames and should be mounted in the vertical plane, close to the source of any potential ignition. It is suitable for use with any of Storagetech’s Pressure Relief, and Pressure-Vacuum Valves, and should be installed on the inlet to the Pressure Relief unit.
