Air Supply Dampers, also called Air Supply Louvers in an air vent cover regulate airflow.
Our Air Supply Dampers (or air supply louvers) assembly for our custom designed grilles, registers and air vent covers include: a wheel lever for accuracy when regulating air flow, a recessed face-plate that allows your new grill to fit tightly against the wall, floor or ceiling. Floor register covers include a sturdy inside grille to support heavy foot traffic for floor vent covers.
All of Classic Grills standard-sized air supply grills include an adjustable damper. For sizes other than our standard sizes commonly available, contact our Classic Grills Sales Team for a quote at Sales@ClassicGrills.com or call 760-213-0427.
