Single AVSU

The Single Area Valve Service Units (AVSU’s) are manufactured under BS EN 13485 Medical Devices: Quality Management Systems and Medical Device Directive 93/42/EEC (CE0086) Class IIb. They provide a local gas isolation facility for use during normal installation and maintenance or in the event of an emergency. They are built in accordance with the HTM02-01, C11 and BS EN 18082 standards and are suitable for Oxygen, Nitrous Oxide, Oxy-Nitrous Oxide, MA4, MA7, CO2 and Vacuum (other gases on request).

Compact Multi Valve AVSU

  • The AVSU can be installed as a flush or surface mounted.

  • Housed in a steel white epoxy coated box and a key operated 90° lock for security with 20,000 lock combinations.

  • Gas Identification is located on the body of the AVSU behind the window and immovable.

  • A large viewing window to the door gives immediate indication of Gas Identification located on body of AVSU, valve position and flow direction.

  • In an emergency this can be gained by pulling the window thus allowing access to the valve. Anti-Tamper device can be fitted to the window and connected to our Digital Alarm and BMS to incorporate monitoring of all CPX AVSU’s.
