Spectra Gases 2701 series medical gas changeovers provide fully automatic system control. An integrated circuit board monitors cylinder bank pressure electronically, controlling changeover and eliminating the need to manually reset levers or valves.

changeover system is designed to allow the user to
replace expended gas cylinders while maintaining a
continuous gas supply to the point of use.
