Frequently Asked Questions

It filters paint or coating material before it hits the nozzle — removing lumps or debris that could clog the tip, spoil spray pattern or damage the pump.

It’s not recommended. Skipping the filter increases risk of nozzle clogging, poor finish, pump wear or damage — especially with thicker paints/coatings or contaminated fluids.

Inspect the filter regularly — clean or replace if clogged, especially after using thick or particulate‑laden coatings. For frequent spray jobs, check before each job or if spray pattern worsens or pressure drops.
