The nozzle screw has an M8x1 exterior thread onto which you can screw a flexible cannula to apply the coating material even to places that are difficult to access.
The hand-held spray gun operates based on the airless principle, which means the spray jet is exclusively generated by the material pressure, which presses the material through a nozzle. After exiting the nozzle, the spray jet takes the shape specified by the nozzle. It is directed towards themwork piece. The effective spray jet is not quite as wide as theoretically possible.
The coating material that is to be processed is applied to the surface by a person who is manually guiding the hand-held spray gun over the surface that needs to be coated and who is starting the spraying process at the respectively intended location by operating the pull lever. The coating material is fed to the hand-held spray gun in liquid form under high material pressure.
Pulling the pull lever towards the handle of the main element moves the valve needle back against the resetting force of the valve spring. The valve needle pushes out of the valve seat of the nozzle screw and thereby releases the material flow.
The volume of the exiting material depends exclusively on the nozzle size and the material pressure!
The volume and shape of the jet can only be modified by changing the nozzle. The diameter of the nozzle bore determines the material flow volume, while the size and geometry of the nozzle opening determine the height and width of the jet.
