Outside Air Damper Leakage Solutions
Outside Air Damper Leakage Solutions
(OP)
I have some really old outside air dampers in office buildings . Maybe 15% leakge or so when fully closed.
I'm looking to go to low-leak dampers or else just go cheap and add some blade and edge seals on the current ones.
My question is this , has anyone out there had any experience with these low - leak dampers ? I am concerned about sick building syndrome .

RE: Outside Air Damper Leakage Solutions
I'd recommend looking at ASHRAE 90.1. Depending on the climate zone, you should be looking at anywhere from 4 to 10 CFM/SF at 1.0 IWG. If the dampers are bad, I'd also recommend looking at linkage/actuator.
