Exposed Vestibule Exception (ETA) Unheated Air Curtains

The ETA air curtain has been tested in accordance with ANSI/AMCA 220 and meets the criteria to be used as an exception to costly, space-consuming vestibules. The ETA is used to stop cold or warm air from entering a climate-controlled environment and is designed for all retail, grocery, agricultural grow farms, 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.
