Kanger Airflow Control Valve - Protank II, Protank 3, Aerotank. This base can be used to upgrade a Protank II or Protank 3 to have adjustable airflow or it can simply be used to replace an Aerotank base. Turn the dial on the base to increase or decrease airflow to your preference.
The Kanger Airflow Control Valve does not change the type of atomizer heads you can use in your Kanger tank. The Protank II with Airflow Control Valve will still use the single coil Protank II/EVOD atomizer head, and the Protank 3 with Airflow Control Valve will still use the Dual coil Protank 3/Aerotank atomizer head.
