Here are a few shots of the fume exhaust fans for a life science building we are just completing (high silver LEED award anticipated). Quite a bit of leakage was found during smoke "bomb" testing of the systems and a closer look at the way the fans were constructed sure showed us why. Take a look at the gaps in the bolted face of the fan scroll and the squeezed out gasketing where it was used. Unfortunately, the campus/system standards call for these fans to be installed in a mechanical space, so now the issue is whether there is an unsafe condition in that space for the maintenance workers.

Funny you mention this. We had installed a Carrier Centurion roof top recently and it leaked considerably. Prior to the T&B rain was finding it's way into the unit. It was a downblast configuration thus the rain water was finding it's way down the duct and into the building. T&B confirmed that the unit was poorly constructed. Tried to get Carrier out to look at their product but they'd rather stay on the other side of the phone.
Who's fan's are these?
