The 523 Series AutoSwitch is a continuous gas delivery system for high purity gas service, typically in the laboratory or process plant, that automatically changes cylinder or bank priority from the primary source to a reserve supply without transmitting pressure fluctuations to the use line.

Options include internal pressure switches with warning lights for cylinder depletion or internal pressure transducers without warning lights. Both may be used with an Altos alarm.
