Compact Multi-Valve AVSU
The Compact Multi-Valve AVSU is the visible area isolation point for a clinical zone. It allows the operations team to cut gas to a defined area within seconds during an emergency or maintenance, without affecting the rest of the facility.

What is it?
The unit is installed in a visible, accessible position at the entrance to the area it serves. It contains an isolation valve per gas, pressure indication, a front break-glass panel for emergencies, and identification showing the gas and the area served. Gas count and sizes follow the network design and the approved project specification.
Features
- Rapid area isolation in emergencies
- Pressure indication for each gas
- Break-glass front panel when required
- Clear identification of gas and area served
- Visible and accessible location
- Connectivity with the area alarm panel
Applications
- Hospitals and medical complexes
- Operating theatres and intensive care units
- Emergency and inpatient departments
- Dialysis centres
- Day-surgery centres and clinics
- Expansion and refurbishment projects in healthcare facilities
