Turning Vane


Does anybody have experience making / installing a turning vane / scoop / wedge in ducting to improve air flow. I have attached a sketch to demonstrate what I am trying to accomplish.

The sketch is of the supply feeding the overhead duct. Any help/ideas are appreciated. I would also like to do something similar in the supply plenum.

Thanks.

Turning Vane


What is the main purpose of the turning vane? Air flow or noise?
Thanks

Turning Vane


What you drew is not a turning vane. A turning vane would not be the full length/height of the duct like you have it. What you have drawn will help though, but turning vanes would help more.
