Crossdraft Paint Booths for North Carolina Fabricators
For a North Carolina fabrication shop putting primer and topcoat on steel weldments, a crossdraft booth is often the first enclosed booth and sometimes the only one it needs. Air enters through filtered front doors, sweeps the length of the cabin and leaves through rear exhaust filters. Double D Mechanical installs, moves and services crossdraft booths and the systems around them.

Heavy equipment builders like Deere, with its excavator plant in Kernersville, rely on suppliers for fabricated parts that arrive primed or finished. Those weldments are odd-shaped, heavy and coated with durable industrial paints. A crossdraft booth handles that work well, and its flat floor accepts carts, stands and forklift traffic without grates.
Positioning the Part in the Airflow
In a crossdraft booth, where the painter stands relative to the part and the airflow matters. Spraying with the air at your back keeps overspray moving away from the painter and toward the exhaust. The part should sit far enough from the exhaust filters that air can wrap around it. We lay out stands and lighting with that in mind.
- Leave room between part and exhaust filters for even airflow
- Use stands or turntables so every face can be sprayed with the airflow
- Place lights so the downstream side of the part is visible
- Keep fixtures and carts from blocking the door intake filters
Ducting and Utilities
The crossdraft exhaust chamber is at the back of the booth, so the fan and stack go there, through the roof or out a wall. If a make-up air unit feeds the booth, its supply duct lands at the front intake plenum. Electrical service covers the exhaust fan, lights and controls, and gas covers the make-up air burner. We coordinate interlocks with spray equipment and fire protection.
When It Is Time to Move or Upgrade
Shops that outgrow a crossdraft booth sometimes move it to a new building, add a heated make-up air unit, or replace it with a semi downdraft booth. We help you decide which makes sense based on the parts you paint and the finish your customers expect, and we do the mechanical work for whichever path you choose.
Planning a booth or oven project in North Carolina
Crews mobilize from Houston; North Carolina is roughly 950 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in North Carolina is concentrated around Charlotte, Raleigh and Durham, Greensboro, and Winston-Salem. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include aerospace, automotive and EV, furniture, and heavy trucks.
Hot, humid summers and mild winters put the emphasis on make-up air cooling or tempering, filter change schedules and keeping intake away from loading doors.
Frequently asked questions
Is a crossdraft booth enough for equipment weldments?
For primers and durable industrial topcoats, usually yes. If customers expect a cosmetic finish on large surfaces, a semi downdraft or downdraft booth may be worth considering.
Can a crossdraft booth be upgraded later?
Common upgrades include adding a heated make-up air unit, pressurized intake plenum, better lighting and upgraded controls.
Where does the exhaust fan go?
At the rear of the booth on top of or behind the exhaust chamber, with the stack through the roof or wall.
What do you need to quote an installation?
Booth dimensions or model, floor plan, largest part, roof or wall details for the stack, and nearby electrical and gas service.
