The process
Grit blasting halls recover abrasive and dust through cyclones and bag filters, and painting halls exhaust solvent-laden air with overspray. Large volumes at low pressure, spark resistant where solvent is present.
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.
