- The special design and internal baffles of Taco Air Scoops® slow water velocity to separate the air from solution. Thanks to this design, Taco Air Scoops efficiently remove air to provide noiseless, air-free hydronic heating, cooling or combination systems. They also provide an economic way to integrate air elimination by the connection of either a plain steel or diaphragm expansion tank. Quality features include one-piece, cast iron construction, and engineered baffle to separate air from water, maximum operating pressure of 125 psi (862 kPa) and maximum operating temperature of 300 deg F (135 deg C).
Taco® Air Scoop® Air Scoop, 1 in Nominal, FNPT, 125 psi Working, 300 deg F, 8 fps, Cast Iron, 6 in W x 4 in H
- 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
