Apeks DS4 1ST Stage

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.The performance and internal workings are the same as a XTX40/50 1st stage, but this unit has no swivelling turret, thus making it a more compact unit. And having the APEKS dryseal system is ideal for cold water diving or warm water diving.
