One piece cast iron construction |
Engineered baffle to separate air from water |
Never requires any servicing |
Media are water, water/glycol mix |
31.4 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 |
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 |
