Watts has introduced its Series AS-B Bronze Air Scoops (air separators). These air scoops are designed for efficient separation of air from water in hydronic heating systems. Watts Series AS-B is manufactured completely out of bronze and is mounted in the horizontal position. These scoops have tappings for the installation of an expansion tank, air vent and for boiler fill piping, and they come standard with a Watts Model FV-4M1 automatic vent valve. The Watts Series AS-B disperses entrapped air in the hot water heating system piping as water is recirculated through the use of its internal agitator. This provides quiet, efficient operation of the hot water heating system radiation.Watts Regulator Co.
