FAQ Category: Firesafe Flowmeter

The Firesafe™ Cannula Valve and Firesafe™ Nozzle have been carefully designed to minimise resistance to the flow of oxygen. Considering the worst case – an oxygen concentrator with a non-backpressure compensated flowmeter calibrated at atmospheric pressure. If two Firesafe™ valves were installed in series, at an oxygen flow of 5 l/min, the actual oxygen flow … Read more

Where an oxygen concentrator is being used, it is recommended to install a Firesafe™ Nozzle at the interface between with the concentrator oxygen outlet and the oxygen tubing to isolate the oxygen supply at source in the event of a fire. A Firesafe™ Cannula Valve should then be installed close to patient, normally at a position … Read more
