Wrong filters compromise performance. WERCS specifies optimal filtration.

Work Positioning

Vehicle placement is critical. We help optimize positioning for your booth.

Rear Exhaust Issues

Rear exhaust systems need regular maintenance. We keep exhaust functioning properly.

Makeup air must match exhaust. We verify and adjust air balance.

Semi-Downdraft Paint Booth Service FAQ

Common questions about our services

Semi-downdraft typically has partial ceiling filtration with rear exhaust, while side-downdraft has full ceiling coverage with side wall exhaust. Both are improvements over crossdraft.
Semi-downdraft can produce good automotive finishes when properly maintained and used correctly. Work positioning is more important than with full downdraft systems.
Proper vehicle positioning under the filtered area, correct spray sequence, and regular maintenance are key. WERCS can help optimize your process.
