Semi Downdraft Paint Booths for Wisconsin Ag and Heavy Equipment
Ag equipment builders and fabrication shops in Wisconsin often paint implements, frames and components that sit on carts or stands rather than rolling in on their own wheels. A semi downdraft booth gives those parts better overspray control than crossdraft, while staying above the slab in buildings where a pit would interrupt production.
Discuss your installationParts on Carts and Stands
When the workpiece is a frame, hitch, hopper or panel on a cart, the painter needs room to circle it and light on all sides. Cart position relative to the ceiling intake matters, since that is where air is cleanest and moving down. We lay out cart stops and the work zone around the airflow so the most important surfaces get the best air.
Heated Air for Steady Results
Replacement air has to be warmed before it enters the booth, and a cure cycle helps parts move on faster. Burner size, controls and duct layout determine how quickly the booth reaches temperature and how well it holds it.
- Confirm coating cure requirements
- Size burner and gas service accordingly
- Set recirculation for cure mode if used
Fitting Into a Fabrication Building
Fabrication shops often have overhead cranes, welding areas and material storage close by. The booth location should keep weld smoke and grinding dust away from the intake and leave crane paths clear. Duct routing and the air make-up unit location are planned around the building's existing steel and equipment.
Relocation and Expansion
As shops grow, booths move. A semi downdraft booth can be taken down, relocated and reinstalled with new seals and filters, and sometimes lengthened with added panels if the plenum and exhaust are adjusted to match.
Planning a booth or oven project in Wisconsin
Crews mobilize from Houston; Wisconsin is roughly 1,000 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Wisconsin is concentrated around Milwaukee, Madison, Green Bay, and Appleton. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include heavy machinery and engines, paper products, food processing equipment, and metal fabrication.
Cold winters mean make-up air heaters are sized for sub-freezing intake, and booth or oven placement has to account for frost lines, snow loads on roof penetrations and winter slab work.
Frequently asked questions
Is semi downdraft good for parts rather than vehicles?
Yes. Parts on carts benefit from the downward air at the front of the booth, and layout can put the work in the best part of the flow.
Can a booth be lengthened later?
Sometimes, by adding panels and adjusting plenum and exhaust. Fan and air make-up capacity has to be checked for the new size.
How do we keep weld smoke out of the booth?
Locate the booth and its intake away from welding and grinding, and keep the booth slightly positive so outside air does not leak in.
What does relocation involve?
Documenting the booth, disassembly, transport, setting it in the new location, new seals and filters, and reconnecting ductwork, utilities and controls.
Can you work around an overhead crane?
Yes. We plan booth location and duct routing so crane paths stay clear.
