Suggestion:  If you use air tracks don't go for a central blower--too 
expensive and your architects/engineers will overdesign and otherwise screw 
it up.  Think commercial air-track blowers mounted below (or above, or 
behind a wall) with on/off switches and a valved connector within the room. 
This ($5,000) solution to our remodeled labs came from the two of us here 
and replaced the $50,000 solution that the engineers were going to install. 
We have each blower feeding two stations--each station with a control valve 
(plastic).  The reduction in noise is fantastic.
