AIR RELEASE FOR WET SPRINKLERS

The FM approved United Fire Systems Model AR-1 Wet-Pipe Fire Sprinkler System Air Release is a device for automatically releasing the trapped air from the high point(s) of a wet sprinkler system. Trapped air contains oxygen, which, when combined with water, is the primary cause of internal pipe corrosion. This corrosion can lead to pipe blockage, leaks, and pipe failure. The Model AR-1 air release is installed at the system high point(s). Air is vented until water reaches the internal float valve, which automatically closes the device to prevent water release.
