A lower-speed curtain selection is unsuitable for the design airflow.
This model identifies the 4000 fpm vertical configuration explicitly.
The larger opening accommodates a wider stored curtain while retaining the narrow frame format. This configuration addresses vertical penetrations where operating air velocity exceeds the lower-speed selection.
