So the new style on/off does not vent in the sense like the old style did. There is a bleed hole on the top portion of the ASA body that will vent should you try to remove the tank while fully gased up. The best way to clear your air supply is to turn off the air, pump and shoot your gun a couple of times, making sure if your not on the field (or in a protected area) that you have no paint in your gun. This will clear or remove all air that is chambered in the marker.
