Standard Features

Vortex air separators eliminate entrained air from heating and cooling systems, improving heat transfer efficiency. Armstrong’s Models VA/VAS in cast iron are available in 2”, 2 1/2” and 3” sizes, and fabricated steel in 4” to 24” sizes. Sizes larger than 24” are also available.

• Air-free water flow means improved systems operation and reduced costs.
• Armstrong Vortex Air Separators eliminate entrained air from heating and cooling systems. The result: better performance and lower operating costs.
• Permits quick venting of air at start-up
  reduces annoying noise caused by air entrained in the system
• Reduces service costs due to air-bound piping
• Extends the life of your system by reducing corrosion and erosion
  improves heat transfer efficiency in boilers, fan coils, chillers, etc.
• Reduces the overall energy costs of your system
• Vortexing action results in more air elimination than with straight flow separators optimizes pump performance
