DIAMOND /DIAMOND ICE REGULATORSSECOND STAGE

Second stage with air balancing system whichreduces the initial breathing effort while pro- viding a linear and constantly smooth breath- ing. The system operation is based on a pneu- matic piston working in close contact with the spring, enabling the latter to work with a lower load force (consequent light breathing) ensuring a perfect seal of the air flow during the breathing out phase.

ENGLISH

By actuating the knob located on the left of the regulator (see Figure A-B) you can regulate the breathing softness according to your breathing demand and to the diving conditions. By rotating it anticlockwise you will get the maximum breathing softness and by rotating it clockwise you will gradually reach a stan- dard breathing flow. This second stage conse- quently allows individualizing the breathing demand as a function of the dive require- ments and type. The operation is of the “Downstream” type.This system allows for low air consumption by reducing air waste, as it perfectly meets the breathing demand. This means that the air flow delivery is per- fectly controlled by the diver’s breathing ac- tion: a normal breathing action produces a light air flow, while heavy breathing due to fatigue or deep diving produces a free air flow, also increased by the Venturi effect. In addition, this system also provides safety margins in case of first stage overpressure: should the intermediate pressure supplied by the first stage suddenly increase, the second stage would continue to work, thus releasing excess pressure and enabling the diver tobreathe. The control of the DIVE and PRE-DIVE mecha- nism allows to insert the Venturi effect. This system is placed around the knob regulating the breathing effort reduction system. By actuating this mechanism placed to the left of the second stage you can insert the Venturi effect and consequently increase air delivery. By turning the lever towards the outside you reach the “PRE-DIVE” position, while by turn- ing the lever towards the diver you reach the “DIVE” position. (see Figure C) The “PRE-DIVE” position is recommended to prevent accidental delivery when the regula- tor is under pressure but not used, while the “DIVE” position is recommended during the dive. Warning! Move the lever to “PRE-DIVE” only when the regulator is not used, and rotate it to “DIVE” before dive start. The main body is made of synthetic resin,which is highly resistant to impacts, abrasions, ultraviolet rays and chemical agents. Di- aphragms are made of medical grade silicone, while nitrile rubber O-rings are of different hardness (Shore) as a function of their appli- cations. Chrome-plated brass and stainless steel internal components. Black anallergic silicone mouthpiece. The nut placed on the hose end was especial- ly designed with slightly marked lines for cos- metic purposes, so as to give the Diamond regulator a professional and captivating look. The hose is of the standard type (770 mm length and 3/8” thread).
