Cleaning and Maintenance
Volatile Organic Compounds (VOC)
Regulation
In certain states, spraying solvents that release VOC’s into the
atmosphere when cleaning a spray gun is prohibited. To comply
with these air quality laws you must use a cleaning method that
prevents the escape of VOC vapors into the atmosphere. See
Compliant Cleaning Methods
below.
Compliant Cleaning Methods
•
Place spray gun in a gun washer that completely encloses
the gun and components during cleaning, rinsing, and
draining.
•
Spray solvent through the spray gun into a closed gun
cleaning station.
