Duct Takeoffs on Supply Trunk

brian_wiley | Posted in Mechanicals on

Hi all,

Can anyone tell me if there are any performance issues with having duct takeoffs not be centered on the supply trunk? Because of space constraints, it would be ideal to have the takeoffs be on the top half of the supply trunk (which is running horizontally, of course), but I can conceivably center them with quite a bit of extra labor if means a significant increase in performance.

Thanks,

Brian

    I don't see a problem, and ducts get connected in non-centered locations all the time. If you do end up with any airflow issues, just install a turning vane in the main duct to divert a little airflow to make your branch run do what you want.

    Thanks so much for the reply, Bill. That puts my mind at easy, and makes it much easier to run the ducts that I want.
