Automatic spray guns

Product at a glance

The A 20 spray gun complements the product range of the automatic spray guns. Thanks to the quick-change adapter system, the apparatus can be changed in seconds and the settings of the spray parameters are maintained by the adapter in the plant. The air parameters can be changed with only one tool, so no unintended adjustment is possible.

All settings, locking part, air controller and ventilation nozzle fixation are designed to be quickly and easily set and fixed by the user. Due to the new aluminium oxide polymer composite coating of the surfaces, the apparatus and adapter are particularly robust and easy-care, but also available in stainless steel. A new needle connection gives an exact and wear-resistant tightening of the needle. A specialist is the A 20 for processing high-quality surfaces made of wood, metal or plastic. It is ideal for use in coating lines and systems.

Operation

The automatic sprayer is available with conventional compressed air atomisation as well as in the HVLP version. Due to various air caps (nozzles) that are optimally adapted to the surface quality of the different coating materials, the spray pattern is optimally matched to the workpiece.
