The Barberi® automatic air vents allow to remove air from the installations without manual operations. They are normally installed in heating systems, central heating rooms, heating generators (wall-mounted boilers, solid fuel generators, heat pumps). Thanks to the air removal they allow a longer system life without component oxidation, a higher thermal efficiency, a better working and safety of pumps. For a better air removal, the valves must be installed in the upper parts of the systems and in all areas where there is a risk of air bubble forming (reverse syphons, manifolds, storages, boilers).
