Frequently Asked Questions
Yes—it's compatible with ProX17, ProX19, and ProX21 (Stand & Cart). It also fits A60 ProPlus, A80 ProPlus, ProS19 ProPlus, and ProS21 ProPlus. Some ProX7/ProX9 and XR units use the same interface; verify your manual to confirm.
40 MESH is coarser and ideal for heavier paints (latex/primer). Finer meshes capture smaller particles but may reduce flow with thicker coatings. Always match mesh to material and tip size recommendations.
Replace when you notice frequent tip clogs, pressure spikes/drops, or visible damage. With regular flushing and clean materials, many pros replace every few projects or when performance changes.
Yes. The form-fitted one-way design ensures proper orientation. Inserting backwards can restrict flow or cause malfunction.
