Let's analyze the System Advantages:

1. Safety: the added gases (in particular O2 ) and the air are blended at low pressure
2. Space: this blending unit has the size of approx. a shoe box
   Complete Blending: working at ambient temperature, the gas blending is faster and more accurate
3. Accurate Blending: the mixture is continuously analyzed during the bending process
4. Simplicity: it demands only few minutes for its installation and setting up
5. Speed: the Nitrox/Tri-mix filling can be done with the same speed as that one of the air
6. Transport: this blending unit can be easily carried and, for the basic model, it does not need any power source therefore making its use possible also with portable compressors with petrol engine
7. Price: the system price is contained, the oxygen and helium use is total without gas oddments or wastes
