Description
2nd stage XS2
The body of the 2nd stage is traditionally sized, made from hi-tech polymers and with a lateral valve downstream system with adjustable orifice, simple and extremely reliable.
A flow of pilot air is channelled to the mouthpiece by injection, enhancing the performance. The 2nd stage comes with a a flow deviator that acts on the Venturi effect, with dive/pre-dive function.
In any case, performance levels are high, and it is suitable for any kind of dive.
1st stage
XS2 comes with the traditional Cressi AC2 piston model. This is a non-balanced first stage with such high performance that it can be compared to lots of excellent balanced models.
The small number of components, the low weight and the excellent materials make it the strongest Cressi first stages, and the most steadfast to maltreatment, a real “working horse” amongst regulators.
An ingenious bush system allows easy and rapid external regulation of the intermediate pressure.
It comes in three versions: INT, DIN 200 bar and DIN 300 bar.
