Frequently Asked Questions
If your machine uses a 1/4" NPSM gun connection and operates ≤ 3600 psi, it’s compatible. This includes most Ultra / Ultra Max II, Mark Series, and GMAX II rigs listed above.
The 515 indicates ~10" fan at ~12" from the surface with a 0.015" orifice—ideal for many interior wall paints and primers. Adjust pressure and technique to your material and substrate.
A 2-finger trigger shortens the pull and improves control in trim and edging work, helping reduce fatigue. A 4-finger trigger can feel familiar for broad, continuous spray passes.
Most architectural coatings: latex/acrylic wall paints, primers, enamels, and stains. For heavier materials (elastomerics, block fillers), verify viscosity, tip size, and sprayer capability first.
Yes. The gun includes an Easy Out filter to catch debris before the tip and reduce spitting. Select the mesh that matches your material and tip size.
