Backfeed into an Area Valve Service Unit via NISTConnecting into the Area Valve Service Unit via NIST allows the Authorised Person (MGPS) to feed medical gas directly into individual departments or sub divisions, allowing for local isolation only or to support the wider system.

The features and benefits of the Backfeed Service include:

• 35% increase in gas capacity* thereby reducing cylinder changeover

• Improved safety as large cylinders not required in patient areas (ref: EFA/2010/008)

• All 4 wheels have brakes to securely hold the kit in position

• Reduced overall weight, 40% lighter* offering manual handling benefits

• Integral valve cylinders provide safe, low pressure connection and disconnection

• Simple changeover from one bank to the other, providing continuity of supply

• Use of a stable mobile unit removes the need to secure safety chains to the wall

The additional flexibility of connecting into medical gas terminal units or into a riser NIST provides a range of alternative locations. This minimises the impact on visitors and patients whilst ensuring an adequate and continual supply during your medical gas shutdown.
