Using filters prevents dirt or contaminants from making their way through the spray system. They minimize possible tip clogs and optimise the quality of your finish.
In a standard airless system, the paint passes through 3 filters before atomisation: inlet screen, pump filter and the gun filter. The first filter is the biggest, the last one, the smallest.
The size of the filter is defined by their number of mesh. The more mesh, the more the material will be filtered.
It is advised to use a smaller filter with less viscous materials (100 mesh) and a larger filter (60 mesh) with thicker materials such as emulsion / latex paints.
