In the use of first stages with a medium pressure surpressure effect, there is an increase of MP (red line) higher than that of the ambient pressure. This increase compensates for the greater respiratory effort required by the increase in density of the air breathed in depth. Maximum limit CE Standards EN 250: 3.00 J / It. Apeks dispensers are tested on ANSTI machines to simulate immersion breathing. The equipment measures the inhalation and exhalation efforts separately as the depth, feed pressure and water temperature change.The test results are processed to evaluate the Total Work of the Breathing Cycle. 1st stage with balanced diaphragm ensures high performance and high reliability at any depth and pressure of the cylinders. The small internal components reduce friction and are protected from the external environment. Air is one of the best thermal insulators. The Dry Chamber system, adopted on Apeks dispensers approved for use in cold water, is based on this factor and ensures the best possible thermal protection.
The dispenser mechanism is totally isolated from the external environment and maintains its efficiency unchanged over time. In the second balanced stages the air coming from the first stage to pressure MP counteracts the opening of the valve The dispensing effort is considerably reduced, with the result of a second stage much more reactive to the inspiratory act, soft and sensitive, especially in depth. The sensitivity can be adjusted by immersing the external handwheel.
When you swim to the surface, the handwheel can be screwed to reduce the sensitivity, while in depth the handwheel can be totally unscrewed to compensate for the increase in density of the inspired air. The greater the sensitivity, the lower the initial breathing effort.
The external control of the Venturi effect optimizes the air injection. Polished chrome finish (XTX 200 PVD only for Tungsten model). 4 outputs 3/8 UNF MP. 2 outputs 7/16 UNF HP.
All the MP outputs allow you to configure the dispenser from right to left. Transformable quickly from right to left. DCE Diver Changeable Exhaust: easily interchangeable drain conveyor (wide or compact). Flexi whip from ultra-light series.
The Comfo-bite mouthpiece practically eliminates the fatigue of the jaw. Aonnections Available in DIN configuration. First stage type Over-balanced, environmentally-sealed air-condiaphragm design.
Body type Forged body in one piece. Number of HP 2 ports (7/16 UNF). Number of MP 4 ports with fifth door option (3/8 UNF). Exterior first stage Chrome on brass marinos. Left or right-handed Convertible Orientation.Use in cold water Yes. Second stage type Pneumatically balanced. Opening force control knob Yes. Exhaust T Replaceable by the diver - supplied with 2 sets. Heat exchanger for resistance to freezing SI. Tube type Braided flexible hose. General scores WOB (Work of Breathing) Average 0.70 joules / liter. Compatible with Nitrox Si, directly, with 40% O2 / Can be 100% clean. The XTX40 Octopus provides the same features and performance as the XTX40 second stage and includes left / right hand reversibility.
It comes with a high visibility yellow front cover and a 36 yellow hose. Suitable for cold water use (below 10 C / 50 F). 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. 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.
Pneumatically-balanced second stage results in smooth, easy breathing. 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.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.
