This video shows how the fluid flow knob directly affects the trigger pressure. This is done in such a way so the amount of fluid being released is clearly visible and can precisely adjusted to a personal spraying preference.

For the trigger to release fluid, the knob has to be screwed back from the completely forward position - if the knob is screwed all the way forward, no fluid will flow. While the knob is being unscrewed, the technician can be seen pulling back the trigger allowing fluid, and continuously more fluid, to flow from the airbrush. When the trigger is pulled back as far as possible, this is the time to stop turning the adjustment knob as it will eventually screw completely off the gun. It is common for experienced technicians to unscrew the knob to the maximum trigger position, leaving it up to their feel of the trigger to determine the spray pressure manually.

Throughout the Airbrush Tanning Procedure Videos, Airbrush Tanning Manual, and just generally throughout our site, we refer to a popular airbrushing method called the circular motion technique. This technique is described as moving the tip of the airbrush in a circular motion using the hand and fingers, as the body of the airbrush is moved in a general direction with the movement of the arm. This circular pattern matched with the straight stroke produces a wider, more consistent spray than an airbrush just being moved in a line motion. The use of this technique is not mandatory or demanded, but can be quite helpful to an airbrush tanning technician.
