Paint Booth Exhaust Ductwork for Automotive Refinish Booths
Automotive refinish booths depend on stable exhaust airflow for spray work, curing modes, and shop comfort. Double D Mechanical installs and relocates paint booth exhaust ductwork for collision, fleet, training, and production refinish spaces with attention to booth style, fan routing, make-up air, utilities, and service access.

Downdraft, semi-downdraft, side-downdraft, and crossdraft booths each place exhaust ducts and fan connections differently. The duct route should support the booth airflow pattern while preserving room for vehicles, painters, doors, and filter changes.
Roof Or Wall Discharge Coordination
Refinish shops often have limited overhead space above offices, parts storage, prep areas, or mixing rooms. Ductwork planning should account for roof structure, wall openings, drainage, existing rooftop units, and how installers will access the route safely.
Shop Pressure And Replacement Air
Exhaust fans should be coordinated with make-up air so booth pressure stays predictable. Air balance can affect overspray capture, door operation, temperature recovery, and the way air moves between the booth, prep station, and mixing room.
Utility And Shutdown Planning
Electrical feeds, gas piping, controls, lighting circuits, and fire protection interfaces may need to be coordinated before ductwork installation begins. A clear shutdown plan helps reduce disruption to estimating, teardown, prep, paint, and delivery areas.
Frequently asked questions
Can exhaust ductwork be changed without replacing the whole booth?
It may be possible, but the existing fan, duct size, booth design, discharge path, and control arrangement need to be reviewed first.
What affects the exhaust route in a collision repair shop?
Common factors include roof structure, ceiling height, office locations, prep bays, mixing room placement, doors, utilities, and existing rooftop equipment.
How does make-up air connect to refinish booth exhaust planning?
The make-up air system replaces air removed by the exhaust fan and helps the booth maintain stable pressure and airflow during spray and cure operation.
What should a shop provide before a ductwork visit?
Helpful items include booth model information, fan data, photos, roof access details, utility locations, and notes about business hours or areas that must stay open.
What needs to stay accessible after installation?
Filters, fans, dampers, motors, belts, controls, and cleanout points should remain reachable for inspection and service.
