I agree- plant air from across the building or even in another building is a 
valid air supply.
I'd add it sure would be handy to have a valve before the AMD in the room. And 
the AMD should be in the room so you can see the gauge of what you're adjusting.
Sep AMD reqd for each DPV.

Subject: RE: Air Compressor location

It is not uncommon to utilize plant air or nitrogen systems which are piped to 
the riser location, those compressors are not located in a riser room.

Subject: Air Compressor location

Is there anything in 13 that requires the compressor to be located in 
the riser room?  We have a room that is too small to fit all of the 
equipment and the compressor.  However, there is a storage room right 
next to the riser room that could hold the compressor.  Is there 
anything that would prohibit this?
