Why a new nozzle technology system?
During recent years, our industry has seen a lot of changes. Complementing the introduction of waterborne paints, primers, clearcoats and other paint materials have also been adapted to comply with legislation. As a result, a wide range of paint system technologies with different viscosities as well as new paint application methods have been and are still being developed.
What was the situation up until now?
Depending on the recommendation of the paint manufacturer and on the properties of the paint material, painters could choose whether they wanted to use the HVLP or the RP technology.
The spray pattern characteristics (fan size and width) and the available material quantity (material flow rate) were varying with the nozzle size, effectively resulting in a smaller fan size and width in case of a 1.0 nozzle size in comparison to a 1.3 nozzle set. We have also witnessed the emergence of many different nozzle variations or specialty nozzle sets in order to accommodate varying climatic conditions as well as different application techniques.
What makes the X-nozzle system different?
Painters can select between the HVLP and the RP technology. The key difference is the fact that end-users now have the choice with each of the two respective technologies (HVLP and RP) between two different spray fan shapes – available in “I” and “O”-nozzle types.
With the increasing nozzle sizes within each of the respective technology (HVLP / RP), the material flow rate increases too, with constant increments---which means that the spray fan size and width remain unchanged across the entire nozzle spectrum.
“O”-nozzles have an oval-shaped spray fan pattern with a larger dry zone and a wet core to accommodate increased application speed at the expense of slightly less application control during the painting process. The film build per coat in comparison to an “I”-nozzle of the same size is slightly higher.
“I”-nozzles instead do have a parallel spray fan pattern with a minimal dry zone and a dryer center, which is ideal for painters preferring a reduced application speed and maximized application control during the painting process. The film build per coat in comparison to an “O”-nozzle of the same size is slightly reduced.
What are the advantages of the X-nozzle system?
Depending on the properties of the paint system, the climatic conditions and application technique, each painter can now select a spray gun with the suitable nozzle set for their individual needs. Due to the new design of fluid tip and air cap, the air distribution insert is no longer required. We have reduced the noise level of this whispering nozzle during application, giving painters the feeling of a softer, more comfortable coating process. The X-nozzles considerably reduce paint waste!
