Air regulation is extremely gently and the amount of air delivered is considerable, even given the traditional piston-balanced first stage. Ellipse/AC2 has no rivals on the market in terms of quality-price ratio.

 

 

Ellipse 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 has an exceptional air flow, a lot higher than what is found on the market for this kind of first stage and that easily stands up to comparison with the balanced models in terms of performance.
