Let’s face it; many things can go wrong with gear underwater, leaving the diver at high risk. Extrair is a last resort security measure that can mean the difference in those emergencies. Extremely simple to use, you just position it like a normal regulator and release the air from the second stage using the control for breathing and exhale, without even opening any valves.
It works like this: It is a half litre tank with a mini-regulator and integrated first stage, demand valve with mouthpiece and automatic refilling valve. Breathing happens just like with a normal regulator and can be facilitated with the purge valve. It is also easy to recharge by connecting the automatic refilling valve to the included adapter and to an air supply. It can be refilled in less than 60 seconds and the pressure can be controlled by the gauge on the adapter.
