You cannot breathe directly out of a scuba tank because of the high pressure. A regulator reduces pressure to safe a level that can be inhaled by the diver. A diving regulator has two parts: the First Stage reduces the tank pressure and connects it to the Second Stage which contains the mouthpiece for breathing
Manufacturer Reference / Part No.: AA0342F-1
The XTX50/DS4 is the same as the XTX50 in terms of performance but uses a different first stage. The DS4 first stage lacks the rotating turret found on the XTX50 first stage and offers one HP port. This compact first stage is a time-proven workhorse that has been embraced by the technical community around the world.
This compact first stage has four medium-pressure ports and one high-pressure port.
Features an innovative Diver Changeable Exhaust system (DCE). The system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. This gives the user a choice, wider exhaust tee for minimal bubble interference (essential for underwater photography) and narrow exhaust tee for a smaller compact comfortable regulator. The regulator is supplied with both sets of exhaust tees.
Can be converted from a right-handed hose configuration to a left-handed one. The process of changing the regulator to a left-handed configuration is both quick and simple. However this procedure must ONLY be performed by an APEKS authorised Service Technician
This model is available with a DIN connection only.
• | First Stage: |
• | DS4 first stage – no rotating turret. |
• | Unique over-balanced, diaphragm design - as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a rate faster than ambient. This results in superior performance at depth. |
• | An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out. |
• | Second Stage: |
• | Pneumatically-balanced second stage results in smooth, easy breathing. |
• | Easy-to-grip opening effort control knob keeps the diver in control. |
• | A silicone exhaust valve improves the breathing performance of the regulator. |
• | A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water. |
• | The Comfo-bite mouthpiece virtually eliminates jaw-fatigue. |
