Use Backdraft Damper to prevent reverse airflow in your indoor grow rooms or tents when fans are switched off. It saves Co2 and prevents the smell from escaping out of the rooms.

Galvanized steel coating allows you to use the damper carefree in every weather condition. In addition, it comes with high-quality rubber gaskets installed already on the outside for an airtight seal.
