pressure of 9,5 bars (145 PSI) above ambient pressure.
The first stage is balanced and delivers air at constant
pressure even as the pressure decrease inside the cylinder.

The first stage features four 3/8" LP ports and two 7/16"
HP ports.
B > VX 100 and VX Iceberg second stage

balanced second stage, witch offers optimum ease of
breathing. An additional adjustment allow the diver to
fine tune the Venturi effect to the dive / diver conditions.
A specially designed front cover offers maximum protec-
tion to the diaphragm and minimizes the side effect of
strong currents. The VX 100 / VX Iceberg second stage
comes from factory with adjustment knob and lever in
the minus position.
C > Venturi lever
This lever, located on the side of the second stage
Housing, enables the diver to control the inhalation
