They also provide an economic way to integrate air elimination by the connection of either a plain steel or diaphragm expansion tank.

• 1-piece cast iron construction
• Never requires any servicing
• Engineered baffle separates air from water
• Each air scoop has a vent connection on top for the installation of a 1/8" Taco 400-3 or 416-1 Hy-Vent and 1/2" bottom tapping for a diaphragm expansion tank
• The 1-1/2 - 4" air scoops also have an additional top tapping for the connection of a plain steel expansion tank
