The ABD-FD combines an automatic balancing damper with a 1.5-hour static-rated curtain fire damper to meet building code requirements. The assembly automatically regulates damper positioning to deliver precise airflow wherever it’s needed and protects rated barriers. It mitigates the stack effect in high-rise applications and improves comfort.
Works across the full pressure range in supply applications. Fastens to the wall via sleeve assembly and is accessible through the damper grill. Comes with an antimicrobial agent that mitigates mold and bacteria growth.
