Integrated Adjustable Venturi System

An Integrated Venturi System (IVS) offers the option of directing air to flow through the mouthpiece or against the diaphragm.

Aqua Lung considers the adjustable venturi so important that, while most manufacturers reserve this feature for high-end products, every Aqua Lung regulator has this control. A venturi adjustment will alter the positive flow of air. A regulator with an effective venturi will generally breathe well, but may free-flow when not in the diver's mouth. A venturi adjustment is very important as this allows for maximum air delivery when required with a minimum switch to prevent free-flow
