  Apeks First Stages in Thailand

 
 
Apeks manufactures an extensive range of first stages to meet the needs of every diver. All are of pressure adjustable, depth compensated, balanced diaphragm design and supply air at exactly the right pressure. As the diver descends the demand for gas increases and to maintain the supply, the intermediate pressure increases relative to the water depth. In the Dry-Sealed System hydrostatic pressure, acting on the outer sealing diaphragm, is transmitted to the primary diaphragm via the load transmitter. These first stages utilize 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. This increased intermediate pressure compensates for the increased density of your breathing gas by allowing a larger volume of gas to flow through the system on demand. The result is superior breathing performance regardless of depth.Diaphragm first stages have a number of advantages over piston type first stages, especially when combined with Apeks Dry Sealed System*. They offer outstanding gas flow, easy maintenance, simple adjustment of intermediate pressure and a sealed mechanism totally protected from all types of contamination and freezing.

* Apeks invented the first successful 'dry' environmentally sealed system and all our regulators intended for cold water use, have this system as standard. Apeks manufactures an extensive range of first stages to meet the needs of every diver.
