Vapor-Vac Interface The negative flow rate of most active, in-house vacuum systems is too high for use with any sealed induction chamber or non-rebreathing system. The Vapor-Vac provides a simple and effective means of attenuating, or decreasing, the negative flow rate of your active vacuum system to levels suitable for use with your non-rebreathing system and accessories. The Vapor-Vac uses a system of flowmeters connected to a manifold to effectively control the vacuum flow rate of each anesthesia station you use. Can be customized to accommodate up to three anesthesia stations including induction chambers, non-rebreathing circuits, stereotaxic devices and imaging systems. Easily modified to connect to any in-house vacuum system. Made to work in conjunction with all our anesthesia accessories for use with active vacuum including the Vapor-Vac Hooded Induction Chambers, Posi-Vac Non-Rebreathing System and SCOOP.
