Blade Type - Air Balance

Single Thickness Blade

Minimize leakage and maximize air performance. Single thickness blades have a thin yet sturdy profile that minimizes the impact on the air stream. Add blade seals for tight closure with minimal air leakage when the unit closes.

Single thickness blades are available for standard control dampers, backdraft dampers, and round dampers.
