Helps prevent outdoor air from seeping into the ventilated area when the extraction fan shuts off.
If you vent air outside, a backdraft damper helps prevent outdoor air from seeping into the ventilated area when the extraction fan shuts off, giving you better temperature control of the grow area.
When used with an extraction fan and carbon filter the Backdraft Damper will further improve odour control in your grow area as no untreated air can escape.
