ModuleVide™ takes a unique approach to sustaining vacuum service in Critical Zones within a hospital or other medical facility. This solution relates to a medical facility with a main vacuum plant connected via a main piping with branches that deliver vacuum to different areas within the facility. Critical Zone branches off the central vacuum piping system are augmented with integrated branch backup vacuum generating devices (ModuleVide™). Upon failure of vacuum in the branch piping, the ModuleVide™ activates to reestablish vacuum service in that branch piping segment. The branch of piping may for example correspond to the surgical theater suit of a hospital. The vacuum capacity of the ModuleVide™ is sized to match the specific Critical Zone branch's expected demand.
