The AC25 is the first stage of the third generation Cressi IP Adjustable Balanced Piston.
It has 2 high pressure ports and 5 low pressure ports. 4 low pressure ports are located on a rotating tower which ensures that the regulator and instrument connections are always in the correct position. The fifth port is a coaxial Hi-Flow port and is located at the top of the tower. The rotating turret rotates 360° and has 5 low-pressure ports designed to allow more connections without getting in the way.
It has an external direct IP adjustment system that can be set using a simple hex key. The high flow conical filter is the same for INT and DIN. The spring and spring bush are coated to prevent rust. Its technologically advanced design ensures constant intermediate pressure and high performance even with low tank pressure. The AC25m has a brushed brass finish with a metallic coating.
It is combined with the Master Cromo, a pneumatically balanced 2nd stage that has an elliptical shape and a side knob for venturi adjustment. The legs are connected with Cressi Safeflex LP hose, which is a better performance compared to the standard hose. AC25m/Master Cromo is available in DIN and INT versions.
The performance of the regulator is equal to, if not greater than, that of more complex products as it keeps the WOB (work of breathing) below 0.78 joules/liter. The regulator meets the requirements of the latest European regulation EN 250:2014 and is certified for use in water above 10°C (50 F).
