Paint and coating manufacturing uses compressed air for mixing, milling, filling and process control, in an environment with flammable solvents and abrasive pigments. The air system must be reliable, clean and specified for the hazardous area.
Key applications
- Mixing and dispersing vessel operation
- Bead and sand mill control
- Filling and canning lines
- Pneumatic conveying of pigments
Air quality and safety
Control air must be dry and oil-free for reliable valve operation. Where air contacts the product, it must be clean to avoid contamination. In solvent areas, equipment may need explosion-proof ratings, and static-safe design is essential.
System design
Provide oil-free compression with drying and filtration, and separate instrument air from general utility air. Redundancy keeps the batch process moving, and corrosion-resistant components suit the chemical atmosphere.
