CRESSI Complete Venturi Flow Control - HZ820070

CRESSI Complete Venturi Flow Control - HZ820070.

When the air flow released into the injector towards the mouthpiece increases as it is subjected to the acceleration known as Venturi effect. The subsequent depression inside the regulator case keeps the seal bent and virtually cancels the second stage inhalation effort. The Venturi effect stops as soon as the divers stops inhaling. The seal goes back to its original position, the lever pushed by the spring rises and the nozzle is closed by the piston.

In order to enhance the Venturi effect, XS Compact is equipped with a new ergonomic flow deviator in two modes, which are clearly shown on the regulator: pre-dive and dive (picture below). The former activates a flow limiter placed in the mouthpiece duct, which cancels the Venturi effect and the auto-releasing. With the latter on, the Venturi effect is able to work at its best, increasing the air flow released by the regulator to the maximum level.
