Ventüer BDS-Series
Gravity Shutters
Gravity shutters are designed for use as exhaust grilles where airflow is intermittent. When the ventilation system is not operating, the self-closing blades prevent reverse airflow and weather ingress. The Ventüer BDS-Series gravity shutters are available in stainless steel or UV-resistant plastic.
