Rich, I checked in with the university coop purchasing system I have and found call for pricing...

I poked about some and found a open purchase history , the micro vent (rack only) for 140 cages, was 13,850.00 no ventilation unit or cages just the auto water. the the double sided shelf system was $1505. The laminar flow unit (?) is an additional 12000. I am not sure if you need that it is a different PO# so not sure what that is. It looks like they ordered 140 cages but it only states list price less a % discount no price.

It looks like it is quite expensive unit.
