A single oil droplet in spray air can crater a perfect finish, producing "fish-eyes" that force a full rework. An oil free air compressor for painting is therefore standard practice in quality coating lines, and CMN's water-lubricated design delivers the clean, stable air that paint shops depend on.
Fish-eyes: oil repels paint, creating bare spots.
Blistering and hazing: moisture and oil trapped under film.
Poor adhesion: contaminated surface at laydown.
Wasted material: rework consumes paint and labor.
ISO 8573-1 Class 0 to eliminate oil entirely.
Low moisture to avoid blushing on fast solvents.
Stable pressure for consistent atomization.
Adequate flow for simultaneous guns or robots.
No oil circuit means no oil can reach the gun.
Near-isothermal 40–50°C discharge eases dryer load.
PMVSD matches air output to the spray booth's variable demand.
Smooth single-screw operation reduces pulsation in the line.
Stage | Function |
Coalescing filter | Remove remaining water and aerosols |
Activated carbon | Polishing for odor/solvent-sensitive work |
Point-of-use | Final guard at the spray gun |
An oil free air compressor for painting is the cheapest insurance against finish defects. CMN's water-lubricated Class 0 compressors remove oil at the source and stabilize the air that determines coating quality.
