Compliance and Restrictions



This damper is designed for enclosure in emergency fire and smoke situations. It can accommodate airflow in either direction. Upon temperature elevation, the dynamic damper closes automatically to prevent the spread of fire and smoke. The factory-installed actuator is prewired to a single junction box to provide easy, single point wiring installation.
