Duo A2 Horn air atomisation


The new Duo A 2 generation of automatic spray guns combines the advantages of the airless technique and the known benefits of compressed air atomisation in a special way. The multi-air distribution system integrated in the fluid head section distributes the atomisation air extremely evenly into the also newly designed air nozzle, ensuring an extremely soft and homogeneous spray jet. The required atomiser air is reduced to a minimum, air consumption is cut, and turbulence in the spray profile is avoided. The Duo A 2 technique ensures superb atomisation, low overspray, high coating power and thus maximum efficiency and cost reduction when coating surfaces.

Duo A 2 automatic spray guns can be easily integrated in all semi-automatic or fully automatic spraying systems. Control, hose connections and fixings are effected in the traditional, functional manner common to all Krautzberger automatic spray guns.
