APEKS XTX50 + OCTOPUS AT20. The classic Apeks design for technical divers. Intermediate pressure impression - Dry chamber first stage In a traditional first stage, the increase in intermediate pressure (MP) is equal to the increase in ambient pressure (blue line).
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. Balanced membrane, with rotating turret. 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. Easily interchangeable exhaust conveyor (wide or compact).
