With this conventional spray process/spray technology, the material to be processed is atomized at a very high air pressure of about 2 to 8 bar. The spraying equipment, painting systems and coating systems are relatively simple and cheap and the necessary air is generated by a compressor.
Airless spray technology is an economical and environmentally friendly spray process with a high application performance. The high pressure pump draws the spraying agent from any desired container and transfers it to the spray gun under high hydraulic pressure via a high pressure hose. With Airless spray technology, fine, airless atomisation is achieved through a specially designed spray nozzle. The spray jet is ejected onto the material at high speed, thereby providing an optimal finish.
Air Combi spray technology combines the advantages of Airless and conventional spray processes. Using this painting method, the spraying agent is transferred to the spray gun under moderate pressure and pre-atomised. The fine spray distribution is achieved by applying regulated compressed air as the paint is discharged. A soft, controllable spray jet is produced with minimum paint mist. Ideal for highly refined painting tasks on large surface areas as well as for angular components and shaped or small workpieces.
HVLP stands for "High Volume, Low Pressure". With this spray technology, the spraying agent is atomized at low air pressure of about 0.2 to 1 bar and at high air volumes. A compressor or a turbine make available the necessary amount of air.
In the case of electrostatic spraying, the paint is electrically charged – generally in the spray gun. These charged paint particles go along electrical field lines from the spray gun to the workpiece. Due to the electrostatic wrap-around effect, it is often not necessary to rotate the parts with this spray technology; this is particularly the case with filigree or pipe-like objects. Even surfaces where it is not possible to achieve a wrap-around effect are suitable for electrostatic spray technology, since there is virtually no overspray.
