Description for Bell & Gossett 112106

See how Enhanced Air Separator works: as system fluid enters through the inlet, (either straight or angle) the diffuser distributes flow evenly across the stainless steel, wire brush-like medium. Air bubbles, even micro air bubbles, stick to the brush filaments. Trapped air rises above the diffuser through a baffle where the air is then released through an opening at the top. De-aerated water then goes back into the system.
EAS is very easy and convenient to install:
-Requires no minimum pipe run.
-Straight or angle pattern installation capability.
-Usable for systems with either steel compression or diaphragm expansion tanks.
-Removable and replaceable +" high capacity vent.
EAS is built to last:
-Rugged two-piece cast iron body and cap construction.
-Internal parts are all stainless steel.
-Vent has a brass body and non-ferrous internals.
Body Type: Cast Iron
Connection Type: Threaded

  • 1" NPT Enhanced Air Separator


    I just placed an order for a new expansion tank. I also ordered this air separator and a industrial automatic air vent. My question is where in the line do these need to be placed, for the tank to operate properly? Is there any specific distances they need to be placed or in a certain order from the tank?

      No specific distance or order is necessary. Most units are placed right near the tank.

      On domestic cold water a convenient locate will suffice.

      On domestic hot water systems which have a return pump or pumps, it should be placed on the inlet side of the return pump, with an expasion tank, sized accordingly.
