STJH-DYNAMIC-FIRE-DAMPER-610X610-4000FPM

Dynamic Fire Damper 610 x 610 mm 4000 fpm Vertical

A medium square curtain damper for higher-velocity vertical air paths.

The 610 mm format provides substantially more opening area than the compact unit.
Spring-driven deployment closes the stored curtain following thermal release.

Введение продукции

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.

Solutions for Your Application

A lower-speed curtain selection is unsuitable for the design airflow.

This model identifies the 4000 fpm vertical configuration explicitly.

The blade stack could interfere with the connecting duct.

Sleeve geometry can accommodate the stored curtain and preserve its travel path.
