Model 721 Automatic Air Eliminator

One size Air Eliminator handles all size jobs. The 721 Air Eliminator combines both air separation and elimination into one economical, easily installed, compact unit. The 721 obsoletes the installation of large separators (up to 10” and 12” pipe sizes) and is ideal for HVAC installations on upper finished runs and pump by-pass applications. It combines a 1” vortex air separator and 720 Air Eliminator Vent mechanism. This prevents air from entering the system in vacuum conditions. Compact size allows installation at the top of a system in finished space or ceiling crawl spaces. The 721 can also provide air elimination when piped across the differential of large capacity pumps.
