Can a flame arrester be placed downstream of the breathing valve?

The back pressure of the breather valve is set at atmospheric pressure. If the flame arrester is installed downstream, the back pressure needs to be reconsidered. For ease of use, it is installed before the backpressure valve. A combined breathing valve has this structure.

A flame arrester should generally be placed upstream of the breathing valve, so that fire protection can be applied before the gas passes through it. Placing a flame arrester downstream of the breather valve may render it ineffective or create safety hazards. Therefore, it is recommended to place the flame arrester upstream of the breather valve. .
