ACU-300 SERIES Gas Cylinder Auto-Changeover Unit

The ACU-300 incorporates two diaphragm sensed regulators into a single body to create a compact Auto- Changeover design. The automatic operation allows a continual supply of pressure between two gas bottles, and the second stage regulators ensures consistent pressure control under varying inlet pressure changes. Check Valves are fitted as standard to prevent gas escaping whilst bottles are replaced. Also available with optional flexible hoses, cylinder connectors, and gauges for quick installation.
