  • Summary
  • Applications

    Air removal from hydronic and HVAC systems – air can get trapped during initial fill, during routine equipment maintenance (including pressure upkeep), and due to the use of cooling towers

  • Description

    The Armstrong vortex air separators create a vortex or whirlpool action, sending the heavier air-free water to the outer portion of the tank, and allowing the lighter air-entrained water mixture to move into the lower-velocity center. At the center of the vortex the air is released from the water, forms bubbles and exits through an air vent or compression tank installed above it.

  • Materials

    Cast iron or fabricated steel (shell), stainless steel mesh (strainer)

Low installed cost

  • Space saving design

Design Envelope

Lowest installed cost. Lowest operating cost.


Improved system efficiency and operating economy

  • Effective air removal right at system start-up
  • Increased heat transfer efficiencies in boilers, fan coils and chillers, for lasting energy savings
  • Fewer ‘air lock’ incidences for increased pumping efficiency
  • Less corrosion and erosion, extending service intervals and overall system life
  • Reduced system noises
