Product overview
The automatic changeover system, in mechanical and electronic versions, switches from a depleted cylinder to a standby cylinder without any break in flow. The mechanical version suits two-cylinder systems and switches when pressure in the active cylinder falls below the set value; the set pressures can be adjusted to user requirements.
It can be used on multi-cylinder banks and handles air, N2, H2, He, acetylene, argon, N2O, P10 and other flammable, non-flammable and corrosive gases, at up to 250 LPM at 6 bar.
