Azimuth is a semi-closed cyclical circuit breathing apparatus , giving constant and controlled flow.

The gas mixture follows a single direction circular path utilizing two different separated way of circulation, to and from the breathing bag.

Especially, the constant flow of gas mixture coming from the nitrox cylinders, by means of the dosing group goes in to the inhalation breathing bag and reaches the corresponding pressure to the diving depth.

The diver breathes the gas mixture contained in the inhalation breathing bag trough the corrugated hose connected to it, via the mouthpiece assembled on the four-way valve and exhals the gases produced by the breathing process in to the exhalation hose connected to the exhalation breathing bag.
The excess pressure generated by the constant flow is vented from the relief valve connected to the bag itself by means of a short flexible hose.

Gases from the exhalation breathing bag go in to the filter and once purified from the carbon-dyoxyde, enter into the inhalation breathing bag.

The quantity of Oxygen methabolized during the breathing process is re-integrated by the oxigen in the gas mixture flow continously conducted in the inhalation breathing bag.
