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 also can supply two users simultaneously.

Cylinders meet all applicable D.O.T. regulations for compressed air cylinders. MSA Air-Supply Hoses must be used to maintain NIOSH/MSHA approvals of MSA Respirators.

Product Information

Holds two standard SCBA air cylinders to provide firefighters, industrial personnel, confined space workers and other wearers of respiratory protective equipment with a portable, compressed air source any time an air-line device is required. Designed for use with MSA pressure-demand supplied-air respirators, including dual-purpose self-contained breathing apparatus (SCBA), the PortAire system consists of a compact air-pressure regulating system housed in a lightweight, yet durable, anodized aluminum frame. The rugged frame protects cylinders, holds up to 100 feet of air-supply hose and serves as a carrying device for user convenience. It can be easily attached to a two-wheel dolly for even more maneuverability. For information on MSA-approved air-supply hose and quick-disconnect fittings, for use with the PortAire system, please check under the appropriate headings.
