Blade Type - Air Balance

Airfoil Blade

Designed for airflow. Airfoil blades have a smooth profile with rounded blade edges. These blades provide efficient airflow when the unit is fully open. We also offer airfoil blades with insulated cores for thermal break applications.

Airfoil blades are available for standard control dampers, life safety dampers, and adjustable louvers.
