So, I have an Iwata Eclipse hp-cs and have noticed a thing when I spray air at higher psi. Since I usually test run with water before I airbrush, I have noticed that it atomizes the water and sprays it out when I spray only air. this happens at higher psi than 20, is this normal. I have a needle set of 3.5.(I bought a new 3.5 Nozzle, but no change) This does not happen when I spray with my 5.0 needle kit. Hope someone knows if this is normal. Regards
