ETA-E

Exposed Vestibule Exception (ETA-E) Electrically Heated Air Curtains

Electric

The ETA-E electrically heated air curtain provides a heated option of the ETA. This air curtain has been tested in accordance with ANSI/AMCA 220 and meets the criteria to be used as an exception to vestibules. The ETA-E provides electric heat from its blower, helping to create a warmer interior climate and enhanced comfort for workers/customers. The unit 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, aesthetically pleasing look.
