WRAS Approved DC Device Anti-Siphon Adaptor with AUK3 physical Airgap
The WRAS approved 1000/551 anti-siphon adaptor is a Type DC Device* that can be fitted to most standard laboratory taps that have a removable nozzle with a 1/2" BSP thread. The fitting of this device gives the tap an AUK3** air gap to prevent backflow.
The WRAS regulations state that all laboratories are potentially category 5 high risk contamination areas and as such all taps have the requirement for the prevention of backflow siphonage to be fitted.
To fit the new Monmouth anti-siphon adaptor, simply unscrew the existing nozzle and screw the anti-siphon adaptor in to it's place. Then refit the nozzle to the anti-siphon adaptor.
It is important that prior to purchase you fully understand the implications of a tap with this air gap.
