The large surface area flame arrestor FA of stainless steel construction, extinguishes any dangerous flashback entering the device in any direction.
A temperature sensitive cut-off valve TV extinguishes sustained flashbacks long before the internal temperature of the arrestors reaches a dangerous level.
The spring loaded non-return valve NV prevents slow or sudden reverse gas flow forming explosive mixtures in the gas supply.
