Paint Shops & Surface Coating

Why filtration matters in paint shops and surface coating

Paint booths and surface-coating lines rely on directional airflow and staged filtration to keep overspray off the finished surface, protect fan and duct equipment, and meet the discharge-quality expectations attached to the site's environmental permit.

Typical filtration stages

Intake air is usually pre-filtered before it reaches the booth to keep ambient dust off the wet finish. Booth exhaust — floor grille, plenum, or ceiling extraction depending on booth design — typically passes through paint-arrestor media (glass fibre, synthetic pads, or cartridge-style arrestors) sized to the booth's airflow and the coating's solids content, sometimes followed by a polishing stage before the fan.

Selection considerations

Arrestor media choice depends on paint type (solvent- or water-based), film build, booth design, and how often the line needs media changed without stopping production. EEC can review arrestor construction, holding capacity, and frame compatibility against a stated booth and coating combination; this page does not claim a specific EEC product is certified for a named regulatory discharge limit.
