What is the difference between the blue gun filters and the black ones? Is it just the plastic?
If we’re talking about Graco gun filters manufactured by Graco, the difference is that the black ones are what’s known as a “60 Mesh” which is what most new Graco sprayers come with and what is typically used for latex paints. The blue ones are what is know as “100 Mesh” and are a tighter screen than the 60’s. The 100 mesh are for fine finish work such as lacquers, cabinetry work ect.. These are available in a two pack which has one each; 60 mesh & 100 mesh. Sprayer manifold filters are also measured in this way so if you do fine finish work you should get both the gun and manifold filters in the same 100 mesh.
