The AF-480 unit provides automatic filling from potable pressurized systems to low pressure hydronic systems while providing safe isolation from potable systems via the built-in dual check with atmospheric vent. The unit features an adjustable pressure range of 7 to 45 psi and ships preset to 12 psi. Unique to the AF-480 is a built-in hydronic side pressure gauge which allows the precise setting of the system pressure without additional downstream gauges.
