This automatic air vent comes preassembled and can be coupled to the end of a wet fire sprinkler system. The valve automatically and continuously vents air trapped in the system to help prevent corrosion and extend the life of the fire sprinkler system, which reduces labor and maintenance costs.
With a purge valve that can be opened to expel large amounts of air and expedites the draining and filling of the system, the 7930ECA can easily be installed on new or existing systems, which deters corrosion within a fire sprinkler system
