FR-08T

Standard Octopus
Adjustable & Unbalance
Clockwise- Decrease Airflow
Counter Clockwise- Increase Airflow

The FR-08T features an audible, diver-adjustable
inhalation effort control. Rotating it counterclockwise
increases airflow, while clockwise decreases it. Once
set to maximum airflow, it emits a “tick” sound, signaling
no need for further adjustment.
