2ND STAGE MASTER CHROME
High-end 2nd stage that combines noise-dampening semi-flexible technopolymers with heavier titanium components.
Pneumatically compensated mechanism that guarantees an exceptional smoothness-flow ratio and an abundant and calibrated delivery of air without the need for a very accentuated Venturi effect.
New oversized titanium inspiratory effort micro-regulation knob, with a regulation mechanism completely isolated from the external environment by means of a double O-ring: it guarantees smoothness and durability. The knob includes a nut for fine regulation of respiratory effort (technical service).
Dive-Predive baffle to manage the Venturi effect. No metal assembly elements.
Elliptical section that allows a lever arm even greater than that of much larger regulators, with an optical effect of much smaller dimensions and greater comfort. Reduced dimensions 7.5 x 6 cm, only 5% larger than the Ellipse Titanium and the lightest of the compensated models on the market with only 205 g.
Oversized intake membrane for greater inspiratory smoothness, the largest in its category: 2,810 mm2, 12% more than competing high-end models. Teflon-coated contact disc with the cam to reduce cam-disk friction.
Cam with a large pivoting angle, highly reinforced to accurately transmit the inhalation effort and with minimal friction with the membrane disk.
Peak inspiratory effort of less than 4 Mbar with a total work of breathing of 0.60 Joulesmin.
Possibility of extracting all the machinery from the box with ease, which greatly facilitates maintenance operations.
Heat exchanger located inside the shell that prevents the air from freezing when diving in cold waters.
Improved exhalation zone to reduce expiratory effort without compromising the sealing of the zone, since it is not necessary to reduce the thickness of the membrane. The design of the exhalation membrane retention system directs the flow 100% channeled towards the nozzles of the whisker, benefiting from a powerful Venturi effect and removes bubbles from the field of vision without the need to oversize the whisker.

1ST STAGE AC25 CHROME
1st stage with compensated piston in T, very modern but, at the same time, easy to maintain and very robust and reliable.
Body wall thicknesses have been optimized to minimize weight. A satin chrome coating protects the 1st stage from knocks and scratches.
Rotating Turret 360º
The T-shaped configuration allows greater integration of the first stage in the profile of the fitting and, therefore, greater freedom of movement for the diver''''s head. The mechanism works transversely to the air inlet and the possible filtration of particles from the bottle that manage to pass the filter does not directly affect the valve.
An advanced study of the internal circulation of the air and an exclusive distribution chamber that channels the volume of air directly to the LP outlets have allowed the pressure drop in forced breaths to be reduced to a minimum level (0.5 bar), guaranteeing use with high performance in any situation.
Particularly effective conical filter inserted without the need for a circlip. Effective filtering surface of 280 mm2 thanks to the development of its particular design.
5 LP outlets (316”) located opposite each other in the main body.
5th coaxial output for better routing of the hoses in case of using two first stages.
Supplied in INT version (bracket) and DIN 300 bar. The thread of the DIN version has been made of stainless steel instead of brass to guarantee greater resistance in the event of falls or knocks.
