VENTURI PAD LEVER
The second stages fitted with a deflator-effect adjusting lever. This lever modifies the
inhaled air flow by means of an internal vane. This allows the breathing performance of your
regulator to be adjusted to match your needs.
When the Venturi pad lever is set on “max” the ease of breathing will be at its maximum.
When the Venturi pad lever is set on “min” the breathing resistance will be increased.
We recommend that you set the knob in the “min” position when you do not have the
regulator on your mouth.
We recommend that you set the lever in the “max” position when you are breathing through
the regulator.
