The Ferroli automatic air vent is a pressure safety measure for the central heating unit. They function by dispersing a build-up of air using a flotation mechanism. A float within the automated air vent opens or closes based on the water level as water travels through the heating and cooling system. If the system is devoid of air, the float will be forced to the top and the vent will be blocked until the water level drops.
