Taco Air Scoop's enlarged design with internal baffles slows the water velocity in order to provide a noiseless, air-free hydronic heating, cooling or combination system, by efficiently separating out the air from the water in any of these systems. The air scoop also provides an economic way to integrate air elimination with the connection of either a plain steel or diaphragm expansion tank. One Piece cast iron construction, engineered baffle to separate air from water
and never requires any servicing.

One piece cast iron construction
Taco air scoops are available in 1 in through 3 in cast iron threaded
Each air scoop has an 1/8 in vent connection on top for the installation of a Taco 400-3 or 416-1 hy-vent, and a 1/2 in bottom tapping for a diaphragm expansion tank
2-1/2 in top to inlet
1/2 x 1/8 in NPT
Engineered baffle to separate air from water
Never requires any servicing
Media are water, water/glycol mix
53.5 Cv
Operation - Air being lighter than water, it travels along the upper portion of horizontal pipe in low velocity hydronic systems
As the air and water enter the air scoop there velocity decreases, permitting the air bubbles to be scooped up by the baffle and direct to the top of the chamber
The air reaching the top of the air scoop is either immediately vented through a Hy-Vent or it moves into a conventional plain steel expansion tank (models 433, 434, 435, 436, and 437), if used
Should the air completely fill the plain steel tank and back down into the Air Scoop, the excess will be removed by the hy-vent without disturbing the operation of the system
