What causes a heavy right or left side pattern with my DeVilbiss CVI?
- NNicholas WilliamsonSep 7, 2025
A heavy right or left side pattern with your DeVilbiss Paint Sprayer is often due to plugged horn holes on the corresponding side, or dirt on that side of the fluid tip. Clean the affected horn holes, reaming with a non-metallic point, and clean the fluid tip. To further diagnose, determine if the obstruction is on the air cap or fluid tip by making a test spray pattern, then rotating the cap one-half turn. If the defect inverts, clean the air cap. If not, check the fluid tip for a fine burr or dried paint, removing as necessary.
