The Air Supply
I run a Sweetwater Blower in my fishroom.  Right now before downsizing it runs 115 filters.  Twenty  of them being corner filters.  The sweetwater blower is plumbed with 1-1/2 pvc pipe(?).  A drill and tap was used to put the brass air valves into the pvc.  The sweetwater blower was placed on a shelf in the high corner of the room above all the racks. 

The Sweetwater blower is very quiet.  We have not experienced any vibration problems that you find in many fishrooms or stores.  The only noise I experience is on the startup of the blower and then the filters blowing bubbles through the water.  It is definately an air blower for the professional :).
