  • Features and More

Features

  • Anti-rotation/anti-vibration pinned float - Creates space between float and air vent wall to prevent float hang-up from debris or variations in separator installation orientation
  • Large-diameter chamber - Slows fluid flow dramatically, combines with concentric, sharp-edged mesh design to cause micro-bubbles to efficiently collect and coalesce, highly effective automatic air elimination
  • Anti-corrosion coalescing mesh - Constructed of glass-filled nylon, more resistant to dissolved oxygen and acidic fluids than plated metals
  • Robust stainless steel float linkages - Reliable float alignment even during turbulent conditions such as filling from bottom
  • Corrosion resistant - All components highly resistant to hydronic chemical additives or unstable pH fluid
  • Air separator with 1/2 in check valve to mount expansion tank on bottom thread
  • Stainless steel float guide pin and linkage
  • Glass reinforced nylon internal element
