It is because an additional department now feeds the 3 smaller sized branches permitting a few of the air to efficiently break clear of the key move and feed into these smaller sized branches.

However, I also found that When you are dealing with huge HVAC units (airflow over 5000 cfm), I need to set the goal airflow to about fifty% or even 40% of the original airflow for diffusers that happen to be closer to their HVAC device.
