Huguenot Laboratories Air Release System is placed at the high point elevation of the wet fire sprinkler system to ensure that trapped air is effectively removed from the internal areas of the fire sprinkler system. This air release system is manufactured with a dielectric coupler, Y strainer, and all brass components to ensure reliable operation. The air release device is formatted with a 3/4 connection port so a vent can be plumbed to a remote location if required.
