Side Downdraft Paint Booths for Indiana Truck and Trailer Builders
Truck bodies and trailers are long, and digging a pit the full length of a trailer booth is a big construction project. Indiana builders often choose side downdraft instead: a ceiling plenum running the whole length and exhaust columns low on both walls. The flow is downward over the unit, and the floor stays as-is.
Discuss your installationRunning the Full Length
A long booth needs even air from one end to the other. Plenum design, intake filter layout and exhaust column spacing set how uniform that air is. Fans and air make-up are sized to the booth's full volume, not just the area right around the painter.
- Booth length for the longest unit plus walking room
- Exhaust columns spaced evenly along both walls
- Plenum sized for even delivery end to end
Drive-Through Production Flow
Trailer and truck body lines move in one direction. Drive-through booths with doors on each end let units roll in from prep and out to cure or assembly. Door type, opening size and how doors seal at the floor all affect booth pressure and daily usability.
Heat and Cure for Production Pace
Production paint shops depend on getting units out of the booth on time. A heated air make-up unit with cure mode shortens drying before units move on. Burner size and gas service need to match the booth volume and cure needs.
Floor and Wheel Paths
A flat floor lets units roll straight through. Floor coverings, wheel guides and any tracks need to be planned so they do not interfere with exhaust columns or door seals. Keep the wheel path clear of the walls where exhaust filters sit.
Planning a booth or oven project in Indiana
Crews mobilize from Houston; Indiana is roughly 850 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Indiana is concentrated around Indianapolis, Fort Wayne, Evansville, and South Bend. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive and powertrain, RV and trailer manufacturing, steel, and aerospace components.
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
Why choose side downdraft over full downdraft for trailers?
It gives downward airflow without a full-length pit, which saves major floor construction on long booths.
Can trailers drive straight through?
Yes, with doors on both ends sized for the trailer and good floor seals.
How long does a trailer booth need to be?
Long enough for the longest unit plus room to walk and spray around the ends. Measure your longest unit including hitch and bumpers.
Does a long booth need more make-up air?
Yes. Air volume scales with booth size, so make-up air and gas service must match.
Do you service existing trailer booths?
Yes, including filter checks, balancing, burner service and door seal repair.
