Why Choose 100 Mesh

  • Better finish quality on thin materials by trapping fine debris before the spray tip.
  • Helps reduce tip clogging and pattern spits for more consistent results.
  • Protects pump and valves by keeping contaminants out of the fluid path.

Usage Notes

  • Match mesh to material: use 100 mesh for thinner coatings; heavier materials may require a coarser mesh.
  • Replace when flow drops, pressure spikes, or tip clogs become frequent.
  • Always follow pressure-relief and lock-out procedures before servicing.
  • Confirm fit by checking your sprayer’s parts list for 235677 or the 490ST filter spec.
Frequently Asked Questions

Mesh indicates the screen fineness. 100 mesh (≈149 micron) captures fine particles suited to thinner coatings to help prevent tip clogs and protect the pump/manifold.

This kit primarily fits the Graco 490ST. If your unit uses Filter Assembly 235677, the filter may be compatible—confirm with your model’s parts list or manual before ordering.

Replace whenever you notice reduced flow, rising operating pressure, frequent tip clogs, or visible debris build-up. Heavy use and dirty materials shorten service intervals.

You can, but a finer screen like 100 mesh may restrict flow with heavy-body coatings. Consider a coarser mesh for thicker paints and textures to avoid pressure spikes and flow issues.

Relieve pressure completely, engage trigger lock, and follow the manual for manifold access. Inspect the screen for dents/tears, lubricate O-rings if specified, and seat the filter fully before re-pressurizing.
