The AC25M model belongs to the third generation of Cressi's balanced piston first stage with adjustable intermediate pressure.

It features 2 high pressure and 5 low pressure ports. Four low pressure ports are located on a rotating turret that ensures the regulator and instrument connections are always in the correct position. The fifth is a coaxial hi-flow port located on the top of the turret. The rotating turret rotates on a 360° axis and features 5 low pressure ports designed to allow the use of multiple connections without creating interference.

It has an external direct intermediate pressure regulation system that allows calibration with a simple Allen key. The conical filter of the hi-flow outlet is the same for the int and din connection. The spring and its bushing are coated to prevent rust.

The technologically advanced design allows the delivery of a constant intermediate pressure while maintaining high performance even with low tank pressures. Ac25m features a matte brass finish with gunmetal metallic coating. It is combined with the master chrome model, the balanced pneumatic second stage with an elliptical shape and a side knob for adjusting the venturi effect
