APEKS DS4/ATX40
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.
All our first stages are available in both DIN and A clamp versions.
The TX40 shares the same high performance, pneumatically balanced 2nd stage with the T20 but with the added feature of a heat exchanger system that virtually eliminates the possibility of 2nd stage freezing.
It also utilises the same dry environmentally sealed 1st stage as the TX50. All the 'T' range of regulators feature the Integrated Venturi System (IVS) that enables you to control the air flow within the 2nd stage at the turn of a lever.
Dry sealed system for cold water.
No turret.
