The first stage - the powerhouse of your regulator - reduces the high pressure air stored in your cylinder to a controllable intermediate pressure of about 9 - 10 BAR. The air then flows along the medium pressure hose to the second stage (demand stage). Apeks manufactures a wide range of first stages to meet the needs of every diver. The DST first stage is one of the world's top 1st stages with proven performance and reliability.
