Air Supply: Portaire System
built 669 days ago
When connected to two air cylinders, the system provides a continuous supply of respirable air. During use of the PortAire System, cylinders can be refilled or changed as required to provide a long-duration air supply. When one cylinder's air supplyis exhausted, the device's integral check valve allows users to switch over to the second cylinder without interrupting air flow. The PortAire System ... can supply two users simultaneously.

After connecting the second air source into the open inlet of the manifold, the user can disconnect the TransportAire System and keep it available until it is time to exit the area.
