What would be the reason to choose an electric modulating barometric damper, such as EBD over a mechanical type like CLBD?
Some potential Cons to the mechanical damper
+ noise of the mechanical damper activating?
+ losses as static pressure due to the mechanical damper needing to be held open?
Some potential Pros to the mechanical damper
+ It is a simplification
+ No need to budget for it on the 24VAC transformer
[Application is a dump zone in this case]
