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 inside the network reduces service costs because of air, Bound piping enhances longevity of your system by reducing corrosion and erosion improves heat transfer efficiency fan coils, In boilers, 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
