Apeks DST First Stage

The Apeks DST 1st Stage DIN offers unparalleled function with its well-developed, fully balanced diaphragm design. The design ensures consistency regarding performance as well as a constant flow of air. Its performance remains unaffected in cases of possible change of cylinder pressure. As you descend in the water, your need of gas increases and in order to maintain the supply, the pressure increases relative to the water depth.
