The process
A paint shop is an air system: conditioned supply through AHUs to the booths, exhaust with overspray through water wash or dry filters, solvent abatement by adsorption or oxidation, and ovens with recirculation fans. Spark resistant construction on the exhaust side.
The gas
Booth exhaust carries paint overspray that cures on anything it lands on, with solvent vapour. Spark resistant, a blade form that is easy to clean, and the fan after the booth filters or scrubber.
Selection for this process
| Carbon | Granular activated carbon bed sized for the solvent load and the required outlet |
| Fan | Spark resistant, on the clean side of the bed |
