phragm first stage with swivel and a VR / VRT / VR Iceberg
/ VR NITROX balanced second stage with Venturi (Dive
mode) and sensitivity adjustments (except VRT).
A > V200 First stage
The balanced diaphragm V200 first stage reduces the high
pressure air in the cylinder to an adjustable intermediate
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. A low
pressure hose links the first to the second stage. The first
stage features four 3/8" LP ports and two 7/16" HP ports.
B > VR / VRT / VR Iceberg / VR NITROX second stage
The VR / VRT / VR Iceberg / VR NITROX second stage are
a pneumatically balanced second stage, witch offers opti-
mum 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 maxi-
mum protection to the diaphragm and minimizes the side
effect of strong currents. The VR / VRT / VR Iceberg / VR
