Model No: 310

Storagetech™’s Model 310 End of Line Deflagration Type Flame arrestors are passive devices that prevent the propagation of a flame or fire from entering into an opening in a pipeline or vessel discharging flammable vapour. The flame cell, under normal operation, allows the free flow of vapour, although it does introduce some additional pressure-loss that must be considered in the design of the system. In a situation where a fire occurs external to the equipment and ignites the vapour, the flames will start to travel back through the system. The flame arrestor will prevent the flame from entering the opening.

This deflagration flame arrestor is suitable for quenching subsonic flames and should be located at the end of a pipeline or exit from a vessel. It should be installed in the horizontal plane and is not for use with pressure relief valves or pressure-vacuum relief valves. A cap and screen protects the vent and restricts dust, wind, rain, or insects from entering and degrading the efficacy of the product. The unit is supplied with an earth point, copper tag and cable. Cap has a special opening mechanism, which allows opening automatically after certain time and temperature, so fire flies freely to minimize the effect.

The cell can be removed for cleaning or replacement.
