Vestibule Exception

PAAC-102

MODEL ETA

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.

Key Design Features

Stainless steel case is 18 gauge 304 stainless steel in a number three finish.

Heavy duty 3/4 HP motors. 1630 rpm each.

For openings up to 14 feet high

High efficiency discharge plenum ensures that air being discharged fills
the entire width and height of the opening. This also lowers the opera­tional sound level.

Sound level: 63 dBA (Measured 10 ft. from unit in a free field based on a 1 motor unit)
