In the second balanced stages the air coming from the first MP pressure stage opposes the valve opening. The dispensing effort is considerably reduced, with the result of a second stage much more reactive to the inspiratory action, soft and sensitive, especially in depth.
Both second stages are reversible, they can be quickly transformed from right to left. A matchless match for quality and performance!
Sensitivity can be adjusted during the dive using the external handwheel. When swimming on the surface, the handwheel can be screwed to reduce sensitivity, while in depth the handwheel can be completely unscrewed to compensate for the increase in
density of the inspired air.
The greater the sensitivity, the lower the initial breathing effort.
The external Venturi Effect adjustment control optimizes air injection. The result is ease of breathing and the prevention of spontaneous delivery phenomena. Available on all Apeks second stages.
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 an overpressure effect of the intermediate pressure, there is an increase in MP (red line) greater than that of ambient pressure. This increase compensates for the greater respiratory effort required by the increase in density of the air breathed deeply.

Apeks dispensers are tested on ANSTI machine to simulate underwater breathing.
The equipment measures inspiratory and expiratory efforts separately with varying depth, supply pressure and
water temperature. The results of the tests are processed to evaluate the total work of the respiratory cycle (Work of Breathing).
