Filter GRACO T-Max 18 mesh 289922 — Replacement spray gun filter for high-pressure coating systems

The GRACO T-Max 18 mesh filter 289922 is a replacement spray gun filter for high-pressure coating systems. Designed for use with professional and industrial spray equipment, the 18-mesh stainless or polymer screen captures particulate contaminants before they reach pumps and spray tips. The filter maintains consistent material flow, reduces tip clogging and supports uniform finish quality across repeated spray cycles.

Advantages

This replacement filter provides fine particle retention without significantly restricting flow, helping to preserve pump life and reduce downtime for maintenance. Its construction is compatible with high-pressure coating materials and is sized to fit GRACO T-Max spray guns and related high-pressure fittings. The 18-mesh opening balances filtration efficiency with throughput to maintain spray pattern stability and finish consistency.

Suitable for

• High-pressure airless and air-assisted spray guns used in professional painting and coating
• Maintenance and parts replacement in industrial finishing lines
• Applications where particulate-free coating delivery is needed to prevent tip blockages

Key specifications

• Mesh size: 18 mesh (screen aperture sized to trap fine particulates while allowing coating flow)
• Compatibility: designed for T-Max style spray gun filter housings and high-pressure coating systems
• Function: in-line filtration for spray gun inlet to protect pumps and spray tips
• Material characteristics: corrosion-resistant construction suitable for common coating materials

How to use

Turn off and depressurize the spray system before replacing the filter. Remove the spray gun filter housing cap, extract the old filter element and insert the 18-mesh replacement ensuring correct orientation. Reassemble the housing and restore system pressure; verify there are no leaks and perform a short spray test to confirm proper flow and spray pattern. Replace the filter at regular maintenance intervals or sooner if surface finish shows signs of contamination or tip flow reduction.

Usage recommendations

Use the filter with compatible high-pressure coating materials and follow GRACO equipment guidelines for maintenance frequency. Inspect the filter during routine maintenance and replace if damaged, heavily loaded with debris, or if spray performance degrades. Keep spare filters on hand to minimize downtime during production or field work.
