Taco® 431-6 Air Scoop, 1 in Nominal, FNPT Connection, 125 psi Working, 300 deg F, Cast Iron
1 Year
For Heating, Cooling, Combination System

Taco®, 431-6, Air Scoop, 1 in Nominal, FNPT Connection, 125 psi Working, 300 deg F, 8 fps Flow Rate, Cast Iron, 6 in W x 4 in H Dimensions

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).

Features

  • 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
  • Engineered Baffle to Separate Air from Water
  • Never Requires any Servicing
  • One Piece Cast Iron Construction
  • The Taco air scoop provides an economic and efficient means to separate air from water in hydronic systems
