Aero Dyne Turning Vane Engineered Sound Control PerformanceAero Dyne Turning Vanes are engineered for sound control and can help improve acoustical performance and room noise compliance.

Because of this, HVAC engineers and designers rely on our vanes when building hospitals, educational facilities and performance art centers.

The precise airfoil contour reduces generated sound power to the lowest attainable levels, and lower sound power results in lower sound pressure.

Laboratory test data (Report no. 48037 dated 9/5/87) proves Aero Dyne H-E-P Turning Vanes & Rail have reduced sound power levels as compared to symmetrical vanes, single thickness vanes and vanes with different center spacing.

Lower sound power levels will result in lower sound pressure levels (dBA) for comparable installations.

Engineered for quiet operation

Additionally, Aero Dyne Turning Vanes direct airflow quietly because of the structural integrity inherent in its design. Unlike competitors, our double wall vanes are constructed for consistent, year after year performance for high airflow operations.

They adapt perfectly to all duct sizes, eliminating the need for two different vane sizes in the system. Our vane and rail system will not break, blow out or fail.

Why do our vanes operate quieter than our competitors?

  • Single wall vanes need every sixth vane welded to the runner or need reinforcements attached for ducts running over 1000 fpm
  • Standard double wall vanes lack positive fastening of the blades to the runner, requiring a tack weld at each end, and leaving the possibility of rattling or detaching

Engineers specify Aero Dyne when acoustical performance is a priority

Benaroya Hall, home of the Seattle Symphony, is Seattle’s first facility designed exclusively for symphonic music performances.

Aero Dyne H-E-P Turning Vanes and Rail were specified by the Mechanical Design Team to reduce generated sound power levels contributing to the overall acoustical performance of the building. Aero Dyne continues to be an important part of any project where high acoustical performance is priority.
