The Tank 510 Airflow Controller is designed to help control the airflow on tanks by covering the airflow notches increasing the resistance felt when taking a draw from your tank.
This is a great accessory for tanks that have a very little airflow.
IMPORTANT NOTE: These are NOT compatible with ANY eGo threaded tanks.
The Airflow Controller screws onto the 510 connector of your electronic cigarette. Attach the Controller first and then attach your tank. With the Controller screwed on all the way down, the airflow notches are unimpeded. But as you can unscrew the Controller it rises up and starts to cover the airflow holes on the tank. You can adjust it all the way until it is snug under the tank.
Price includes one (1) Airflow Controller.
