North Carolina Side Downdraft Paint Booth Installation
Equipment components like booms, arms and frames are long, irregular and heavy. A side downdraft booth handles them well: air enters through the ceiling, flows down the length of the part and leaves through low side-wall filters, with no pit to dig. Double D Mechanical installs, relocates and services side downdraft booths for North Carolina shops.

Deere's Kernersville excavator plant is one sign of heavy equipment manufacturing in the Triad. Excavator booms and arms are long, heavy steel parts that are hard to paint evenly when airflow runs from one end to the other. Side downdraft keeps the airflow pattern the same along the whole part, and the flat floor accepts heavy carts and stands.
Floor Space and Handling
Side downdraft adds width for the exhaust plenums, and heavy part handling adds its own requirements. Booth location should account for both.
- Exterior width with both side plenums plus service access
- Crane, forklift or cart path into and out of the booth
- Stands that keep parts clear of the low side exhaust filters
- Clear floor to move parts without blocking side filters
Mechanical Connections
The booth needs a make-up air unit feeding the ceiling plenum, ductwork joining the two side exhaust plenums, an exhaust fan and stack, gas to the burner and electrical for fans, lights and controls. We install the mechanical systems, coordinate electrical and fire protection with those trades, and balance the airflow at startup.
Relocation and Upgrades
Because nothing is cast into the floor, side downdraft booths relocate well. We take them down, tag parts, inspect motors and burners, and reinstall with new ducting and utilities. Relocation is also a chance to upgrade lighting or controls.
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
Can a side downdraft booth handle heavy equipment parts?
Yes. The floor is the building slab, so it carries heavy parts and carts better than grating over a pit.
How far should parts sit from the side walls?
Far enough that air can flow down the sides of the part and into the low exhaust filters. The booth maker's guidance and the part shape set the distance.
Do side downdraft booths need a cure cycle?
Only if your coatings call for forced curing. Many industrial booths air-dry or flash only.
What causes uneven airflow from side to side?
Unevenly loaded filters, damper settings and duct differences between the two sides. Rebalancing usually fixes it.
