This filter assembly is installed in the fluid system to help capture debris, dried material, and contaminants before they can reach the pump outlet or spray hose. Proper filtration helps protect downstream components and supports consistent spray performance.
A clogged or damaged filter assembly can restrict material flow, cause pressure fluctuations, or contribute to premature wear of pump components. Replacing the filter assembly helps restore proper flow and system reliability.
| Material filtration | Traps debris before it enters the spray hose |
|---|---|
| Component protection | Helps protect pump outlets and downstream fittings |
| Flow stability | Supports smooth and consistent material delivery |
| Restricted flow | Reduced output or pressure drop during spraying |
|---|---|
| Filter damage | Torn mesh or deformed filter components |
| Housing leaks | Material seepage at seals or joints |
| Contamination issues | Debris reaching downstream components |
This filter assembly is compatible with the following airless paint sprayers. Always confirm fitment using the correct parts diagram for your specific model.

Filtration issues can involve multiple fluid system components. When servicing the filter assembly, these parts are commonly inspected or replaced at the same time.
Should be checked for clogging or damage that may restrict flow.
Loose or worn fittings can contribute to leaks and pressure loss.
Connections should be inspected for debris buildup or sealing issues.
