Exposed Vestibule Exception (ETA) Unheated Air Curtains

Unheated

The ETA unheated air curtain has been tested in accordance with ANSI/ AMCA 220 and meets the criteria for use as an exception to the vestibule requirement in Climate Zones 3 and above. The ETA is used to stop cold or warm air from entering a climate controlled environment and is designed for all retail, grocery and office entryways as well as other applications that typically would require a vestibule. This commercial line’s stainless steel construction, stainless steel intake screen, and 45 degree beveled edges give it a modern, pleasing look.
