Paint Booth Exhaust Ductwork for Metal Fabrication
Metal fabrication finish areas handle changing part sizes, carts, racks, weldments, frames, and assemblies moving between prep, paint, cure, and shipping. Double D Mechanical installs paint booth exhaust ductwork with attention to airflow, exhaust discharge, make-up air, utility conflicts, and shop access.
Discuss your installationDuctwork Around Changing Workpieces
Fabrication shops may paint small brackets one day and large welded frames the next. Exhaust duct routing should preserve door openings, crane or forklift paths, staging lanes, and clear floor space so the booth can support a flexible workload.
Controlling Air Near Dusty Processes
Grinding, welding, blasting, and material handling can occur near the finish area. Exhaust and make-up air planning should help keep booth airflow predictable while reducing the chance that dirty shop air is pulled across wet coatings.
Mechanical Interfaces in Crowded Shops
Booth exhaust can compete for space with bridge cranes, bus duct, compressed air, gas piping, electrical trays, and roof structure. Reviewing those interfaces before installation helps define support points, penetrations, and clear service paths.
Walkthrough Information to Gather
The best starting point is a clear picture of the shop layout and the parts that drive the booth design.
- Largest and most common fabricated parts.
- Forklift, cart, and crane routes near the booth.
- Existing exhaust fan, duct, filter, and make-up air details.
- Roof access, wall exit options, and nearby utility runs.
Frequently asked questions
Why review nearby fabrication processes?
Dust and air movement from adjacent work can affect the booth. The exhaust and make-up air layout should account for what happens around the finish area.
Can a duct route be changed during a booth relocation?
Yes, if the new route works with the fan, booth, structure, discharge location, and service requirements. It should be reviewed before equipment is moved.
What clearances matter most?
Booth doors, filter access, fan service, lift equipment, crane travel, roof access, and the material path into and out of the booth all matter.
What drawings are useful for planning?
Booth drawings, roof or structural drawings, utility plans, and a simple floor layout showing nearby equipment and traffic lanes are useful.
