Apeks ATX40/DS4 Regulator - Black
Many in stock
The ATX40/DS4 features a smaller, lighter, lower profile 2nd stage than the TX40 2nd stage.
We believe that your regulator should be as flexible as you are. So the ATX40 retains our well proven diver adjustable venturi together with a 'technician-adjustable' balanced second stage and balanced first stage. The combination of this second stage and the DRY SEALED first stage offers an excellent regulator for diving anywhere in the world at a very competitive price. The design of our second stage offers a smooth breathe which enhances your dive enjoyment.

DS4 First Stage
As the diver descends the demand for air increases. To maintain the supply, the intermediate pressure increases relative to the water depth. In this dry sealed system hydrostatic pressure, acting on the outer sealing diaphragm, is transmitted to the primary diaphragm via the load transmitter. This first stage utilizes a unique over-tracking (over-balanced) diaphragm design, where the intermediate pressure supplied to the second stage increases more than traditional balanced models, as the diver descends to greater depths. The result is superior breathing performance regardless of depth.
Available in both DIN and A clamp versions.
