Q How often should the nozzle be replaced, and how can I determine when it is necessary?
A The replacement frequency depends on usage intensity and the type of powder being used. You should promptly replace the nozzle with an original manufacturer part—which we keep well-stocked—whenever the spray pattern becomes noticeably divergent, narrows excessively, or results in uneven coating.

Q What is the warranty coverage and duration for key components?
A Key components are covered by a one-year warranty. In the event of a non-user-induced quality defect during this period, we provide free repair or replacement services to ensure the continuity of your production operations.
