Features

  • One piece cast iron construction
  • Never requires any servicing
  • Media are water, water/glycol mix
  • 61 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
  • The 1-1/2 in through 4 in air scoops also have an additional top tapping for the connection of a plain steel expansion tank
  • 4 in top to inlet
  • 1/2 x 1/8 in NPT
  • Engineered Baffle to Separate Air from Water
