XS2/AC2 is the most inexpensive regulator in the Cressi range.

The XS2 2nd stage comes with the traditional Cressi AC2 piston 1st stage.

Constantly reviewed over the years, this regulator has lots of admirers in the world due to the fact that it is extremely simple and strong, features that make it easy to use and result in low-cost maintenance.

2ND STAGE.

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. 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.

 

1st STAGE AC2:

Simple piston 1st stage, a "work mule" that is affordable, simple, reliable and robust, suitable for intense use.

This first stage is appreciated by dive centers and professional companies who consider it to be a very rentable tool, due to its low cost and practically nonexistent need for maintenance, as well as a surprising level of performance.

Conical filter with large filtering capacity, essential for preventing infiltration of particles from the tanks.

This feature is especially important for regulators in dive schools and rental agencies.

Air flow administered at 2100 l/min with an intermediate pressure drop in intensive breathing (150 bar) 0.5-0.8 bar (Measurement taken at an LP port with the second stage connected and 150 bar pressure in the tank).

Exterior LP regulation via Allen key, greatly facilitates managing adjustments and technical maintenance.

One 7/16” high pressure port (HP) and four 3/8” low pressure ports (LP).

Complete maintenance kit which includes very affordable spare parts. Weight: Int: 615 g / DIN 480 g
