What the Spray Gun Filter Does

The spray gun filter is one of the final filtration points in an airless spraying system. As coating enters the gun, the filter captures dried paint, debris, and other contaminants before they can reach the spray tip.

Keeping the filter clean helps maintain consistent material flow and reduces interruptions caused by clogged tips.

A filter that has become heavily loaded with material can restrict flow through the gun and negatively affect spraying performance.

Why 50 Mesh?

A 50 mesh filter is relatively coarse, allowing heavier coatings to pass through while still capturing larger contaminants that could clog the spray tip.

This makes it useful when spraying materials where a finer filter could become restricted too quickly.

Filter selection should always be matched to the coating and spray-tip size being used. Thinner coatings and smaller tip orifices may benefit from a finer mesh filter.

50 Mesh vs. 100 Mesh

For these compatible Graco spray guns, two common filter choices are:

• 218131 / 218-131 – Blue – 50 Mesh
• 218133 / 218-133 – Red – 100 Mesh

The 50 mesh filter is coarser and allows larger particles through, while the 100 mesh filter provides finer filtration.

This distinction is important when choosing a filter for the material and spray tip being used.

Common Reasons for Replacement:

• Filter screen is torn or damaged
• Filter is crushed or distorted
• Dried coating cannot be completely removed
• Restricted material flow through the gun
• Frequent spray-tip plugging
• Existing filter is missing
• Routine spray gun maintenance

Airless Sprayer Maintenance Tip

Inspect and clean the gun filter regularly rather than waiting until material flow becomes noticeably restricted.

When servicing your airless sprayer, inspect the entire filtration system—including the inlet strainer, outlet manifold filter, spray gun filter, and spray tip. Keeping these components clean can prevent many common spraying problems.

Finding Parts for Older Graco Equipment

Graco has produced numerous versions of its Contractor and Magnum spray guns over the years, and older guns can remain in service for decades.

That's why we include the original Graco part number and compatible spray gun models whenever possible—making it easier to identify the correct maintenance and repair parts before ordering.

Important:

This listing is for one aftermarket Blue 50 Mesh Spray Gun Filter that replaces Graco Part #218131 / 218-131.

This is an aftermarket component and is not manufactured by Graco.

Always verify the 218131 part number and required filter mesh before ordering. Different coatings and spray-tip sizes may require a different filter.
