Downdraft Paint Booth Installation in Georgia
A downdraft booth pulls air from a ceiling plenum straight down past the part and out through the floor, so overspray drops away from the finish instead of dragging across it. That vertical airflow is why plants coating large, heavy or high-value parts choose it, and it is also why the install touches the slab, the roof and the utility plan all at once. Double D Mechanical installs, relocates and services downdraft booths for Georgia manufacturers, from the Atlanta metro to the Savannah side of the state.
Discuss your installationWhere Downdraft Fits Georgia's Heavy Electrical Work
Coastal Georgia is adding heavy electrical manufacturing. The Virginia Transformer plant in Rincon, near Savannah, is a sign of the kind of work moving into the region: transformer tanks, radiators and enclosures that are large, coated in thick films and judged on appearance as well as corrosion protection. Parts like that benefit from top-to-bottom airflow because there is no side of the part that sits downstream of the overspray. When a plant is finishing tanks of that size, the booth has to be planned around crane access, part carts and the weight that will roll across the grates.
Pit Versus Raised Basement
The single biggest decision on a downdraft project is how the exhaust gets under the part. A full pit gives a flush floor for carts and forklifts but means saw cutting, excavation and new concrete. A raised basement keeps the existing slab and puts the booth floor on a steel deck, which adds a ramp and changes how parts load. We walk both options with your team before anyone commits.
- Pit: flush entry, more civil work, longer lead before mechanical install starts
- Raised basement: no slab demolition, needs ramp length and floor load checked
- Either way: exhaust filters sit below the grates and need a safe way to change them
- Water table and existing underground utilities can decide the question for you
Air Handling and Heat for a Humid Climate
A downdraft booth moves a large volume of air, and every cubic foot exhausted has to be replaced with tempered make-up air. In Georgia's humid summers that air also carries moisture into the cabin, which matters for flash times on some coatings. We size and connect the air make-up unit, run the supply ductwork to the ceiling plenum, set the exhaust fan and stack, and balance the cabin so it holds the slight pressure the booth maker specifies. If the booth has a heated cure cycle, gas piping and burner controls are part of the same scope.
Before the First Site Walk
A productive first visit depends on having the right drawings and numbers on hand. Pull together what you have and we can sort out the rest on site.
- Booth maker drawings or the model and cabin dimensions if the booth is already bought
- Largest part size and weight, and how it will travel into the booth
- Slab thickness information or any past core samples
- Roof framing details where the exhaust stack and make-up air unit will land
- Available gas pressure and electrical service near the booth location
Planning a booth or oven project in Georgia
Crews mobilize from Houston; Georgia is roughly 700 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Georgia is concentrated around Atlanta, Savannah, Augusta, and Columbus. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive assembly and EV, aerospace, transportation equipment, and heavy machinery.
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 downdraft booth go into an existing Georgia building without a pit?
Yes. A raised basement design puts the exhaust plenum on top of the existing slab. You trade floor-level entry for a ramp, so the part handling plan has to account for the step up.
Who handles the concrete work for a pit?
Pit excavation and concrete are usually a civil or general contractor scope. We coordinate the pit dimensions, embeds and sequencing so the mechanical install can start as soon as the concrete is ready.
Do you relocate downdraft booths from one plant to another?
Yes. We disassemble, tag and reinstall the cabin, filters, fans, make-up air and controls. A relocated downdraft booth still needs a pit or basement at the new site, so that work gets planned early.
What maintenance does the pit exhaust need?
Pit or floor filters load with overspray and need regular changes. Grates should come up easily, and the exhaust side should be checked for buildup that restricts airflow and throws off the cabin balance.
Can you service a booth that someone else installed?
Yes. We troubleshoot airflow, make-up air, burner, fan and control problems on existing downdraft booths regardless of who installed them.
