- 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.
- The XTX purge buttons are large and easy to operate. A 2-stage progressive purge is used – press the purge on the side for a lower flow rate, useful where more control is required such as filling lift bags etc, then press in the centre for the full effect of the purge, i.e. when regulator clearing etc.
The XTX50 regulator brings the high performance of Apeks’ top end regulators down to a more affordable budget. Designed to handle sub 10*C water the XTX50 is the go to mid-priced, top quality regulator.
More than ready to take on the challenges of technical diving the XTX50 is environmentally sealed. This prevents ice building up within the regulator which can lead to free flow, and protects the XTX50 against silt or bacterial ingress. In the worst circumstances, this ingress can lead to the likes of E.coli or mould developing inside less able regulators. With the XTX50, you don’t need to worry about that.
The XTX50 DST 1st stage features an overbalanced diaphragm allowing the XTX50 to perform exceptionally well in deep water, as you descend the DST compensates for the increased ambient water pressure around you by in increasing the pressure of air to the 2nd stage delivering clear air to you throughout your dive. 4 low pressure and 2 high pressure ports ensure routing is easy while the swivel head means your hoses can be routed kink free even for complex dive setups.
The XTX50 is made to be configured to suit you. Apeks’ Drive Changeable Exhaust system allows you to swap between a large exhaust for improved bubble dispersal and a compact exhaust that is lighter and takes up less space. A Venturi control and Opening Effort Dial allow you to control the breathability of your regulator to suit your preference and environment. The Comfo-Bite mouthpiece supports your regulator with a bridge that sits across your palate eliminating jaw fatigue, with the added benefit of limiting the dry, filtered air from your regulator drying out your mouth.
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 LP 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.
Pneumatically-balanced second stage results in smooth, easy breathing.
The XTX purge buttons are large and easy to operate. A 2-stage progressive purge is used – press the purge on the side for a lower flow rate, useful where more control is required such as filling lift bags etc, then press in the centre for the full effect of the purge, i.e. when regulator clearing etc.
The large venturi lever has a soft touch rubber grip, which makes it easier to locate and use. The lever reduces the amount of grit ingress and therefore resists any possible friction giving a smooth operation.
Easy-to-grip opening effort control knob keeps the diver in control.
The second stage is manufactured with active protection against infection as all molded parts are produced with an additive that kills MRSA, protects against E-Coli, bacteria and fungi, and is also very effective against viruses, mould, yeast and algae.
A silicone exhaust valve improves the breathing performance of the regulator.
The Comfo-bite™ mouthpiece virtually eliminates jaw-fatigue.
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.
