Modulevide.TM. takes a unique approach to sustaining vacuum service inCritical Zones within a hospital or other medical facility. This solutionrelates to amedical facility with a main vacuum plant connected via a main piping withbranches that deliver vacuum to different areas within the facility. CriticalZonebranches off the central vacuum piping system are augmented with integratedbranch backup vacuum generating devices (Modulevide .TM. ) . Upon failure ofvacuum in the branch piping, the ModuleVide .TM. activates to reestablishvacuumservice in that branch piping segment. The branch of piping may for examplecorrespond to the surgical theater suite of a hospital. The vacuum capacity oftheModuleVide .TM. is sized to match the specific Critical Zone branch's expecteddemand.
