1. stage Apeks DST (XTX 50 1. stage) with mounted 5. outlet
OVERBALANCED, MEMBRANE CONTROLLED FIRST STAGE
The heart of a regulator is the first stage. Most First Stages of Apeks work with an overbalanced, membrane controlled mechanism. With an overbalanced First Stage, as the diver's depth increases, the mean pressure in the tube increases faster than with conventional balanced First Stages. The increased mean pressure compensates for the increasing density of your breathing gas by allowing a greater amount of breathing gas to flow through the system when needed (i.e. when inhaling). The result is an above-average breathing performance, regardless of depth.
DRYING CHAMBER PROTECTED BY DRY SEAL
This device fulfils several purposes, among others it protects against icing up of the main spring, which can occur during dives in very cold waters. In addition, the Dry Seal protects the first stage drying chamber against the penetration of impurities. This means there is no longer any need for greasy silicone oils or grease fillings in the regulator.
The Apeks 1 stage DST offers a lot of comfort due to its rotatable head. The medium pressure ports that come out of it offer a good hose configuration, for example for double unit, mono bottle or stage. Also for sidemount diving the perfect companion. You have the option to mount a 5th medium pressure port on top of the head. (Accessories and not included in delivery)
The DST has 4 medium pressure outlets (3/8" UNF) and 2 high pressure outlets (7/16" UNF)
Of course the Apeks DST 1st stage is cold water suitable and therefore also suitable for temperatures below 10°C.
Here now with the already mounted 5th port
The 3/8 plugs on the 5th port are optional. There are thus 2 pieces of 3/8 connection ports not closed.
