AC25M + Master Cromo Regulator

The AC25 is the 3rd generation of Cressi’s ip adjustable balanced piston 1st stage. This regulator meets the requirements of the last European regulation EN 250:2014 and it is certified for use in water over 10°C (50 F).

FEATURES

• 2 high-pressure ports and 5 low-pressure ports.
• 4 low-pressure ports are located on a rotating turret that ensures that regulator and instrument connections are always in the right position. The 5th port is a co-axial hi-flow port and is located at the top of the turret. The rotating turret swivels on 360° axis and features 5 low-pressure ports designed to allow the use of more connections without interfering between them.
• It features the external direct ip adjustment system that can be set using a simple allen key.
• The hi-flow conic shape filter is the same for int and din.
• The spring and the spring bush are coated preventing rust.
• Its technologically advanced design delivers consistent intermediate pressure and high performance even with low tank pressures.
• The ac25m features a matte finish, in gun metal-coated brass. It is combined with the master cromo, the pneumatic balanced 2nd stage that features an elliptical shape and a lateral knob for venturi adjustment
