2nd STAGE XS2
XS2 is the cheapest regulator in the Cressi range. It has a 2nd stage body of traditional dimensions, made of technopolymers and a “Downstream” regulation system with a side valve (adjustable), simple and very reliable. An I.B.I. which channels a pilot airflow towards the mouthpiece intensifies performance.
The 2nd stage is equipped with a flow diverter that acts on the Venturi effect, with a dive/pre-dive function. Constantly updated for years, it is a regulator that has many followers in the world for its extreme simplicity and resistance, which translates in practice into ease and low maintenance costs. The performance is always high and suitable for any type of dive.

1ST STAGE AC2
1st stage with a simple piston, an economical, simple, reliable and robust work "mule" suitable for intensive use. It is a first stage applauded by diving centers and professional work companies that consider it a very profitable tool due to its low cost and practically no need for maintenance and also with a surprising level of performance.
Conical filter with great filtering capacity, essential to prevent the entry of particles from the bottles. This point is especially important in school or rental regulators.
Air flow rate supplied 2100 l/min with an intermediate pressure drop in intensive breathing (150 bar) 0.5-0.8 bar (Measurements made on an LP outlet with the second stage connected and a pressure 150 bar in the bottle).
LP external regulation by means of an Alyco key, greatly facilitates the management of revisions and maintenance for technical services.
