DST Nitrox DIN 1st Stage Regulator

Apeks Nitrox regulators are suitable for use with up to 100% O2 and are colour-coded for easy identification.

The regulators have been specially cleaned and assembled in our purpose built class ´J´ (10,000) Clean Room using oxygen safe components and lubricants and are available in yoke (´A´) clamp or DIN fitting.

The XTX50 is for the discerning diver who wants the benefits of a feature-rich regulator at a moderate price. This popular regulator has four medium-pressure ports all mounted on a rotating turret, resulting in optimal hose routing while eliminating sharp bends in the hose.

Nitrox equipment will be supplied in Europe in accordance with the EN 144-3 and the EN13949 which states that equipment sold in CEE (European Community) countries over 21% and up to 100% will be manufactured with the special M26 fitting.

Four medium-pressure ports all mounted on a rotating turret. This results in optimal hose routing while eliminating sharp bends in the hose.

Features an innovative Diver Changeable Exhaust system (DCE). This 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.

Optional 5th port is available for sidemount or twin cylinder set ups.

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.

– Braided flexi-hoses are now standard on all models. These hoses are lighter weight, more flexible and more durable.
– Suitable for coldwater use (below 10 C / 50 F).
– Compatible with EAN40 out of the box.

Features:

First Stage:

– Uses the DST first stage
– 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.
– 2 HP ports and 4 MP ports on a rotating turret are angled for optimum hose routing
– An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out.
