Side Downdraft Booths for Michigan Transit Buses and Large Vehicles

Transit buses, coaches and specialty vehicles are tall, long and slab-sided. Around Detroit and across Michigan, shops that paint them need even downward air over a big vertical surface. Side downdraft booths deliver that without a pit, which matters in garages and depots where floor work is impractical.

Big Sides, Even Air

Bus sides and roofs are large uninterrupted surfaces where any airflow problem shows. Ceiling intake across the full booth length, plus low exhaust on both walls, pulls overspray down and away along the sides of the vehicle. Balance between supply and exhaust keeps the booth slightly positive and dirt out.

Reaching the Roof

Painting a bus roof requires platforms or lifts. Fixed platforms along the walls can affect where exhaust columns go, while mobile lifts need clear floor space. We plan access and exhaust layout together so neither gets in the way of the other.

  • Fixed side platforms or mobile lifts
  • Roof-level lighting for inspection
  • Clear paths for lifts around the vehicle

Depot and Garage Buildings

Transit depots and fleet garages often have height for the booth but limited room for an air make-up unit and ductwork. Rooftop or pad-mounted units, duct routing and stack locations are planned around existing structure and other mechanical equipment.

Rail and Transit Components

Some transit work involves rail vehicle components and subassemblies rather than full vehicles. Side downdraft booths handle these on carts or stands, with layout adjusted for how parts arrive and leave.

Working in Michigan

Planning a booth or oven project in Michigan

Crews mobilize from Houston; Michigan is roughly 1,100 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.

Manufacturing in Michigan is concentrated around Detroit, Grand Rapids, Lansing, and Flint. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive assembly and suppliers, office furniture, tool and die, and EV batteries.

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.

Project questions

Frequently asked questions

Is side downdraft good for buses?

Yes. It gives downward airflow over tall vehicle sides without the cost of a full pit.

How do painters reach the roof?

Using fixed platforms or mobile lifts planned into the booth layout.

Where does the air make-up unit go?

Often on the roof or on a pad outside, depending on structure and available space.

Can the booth handle smaller vehicles too?

Yes. A large booth works for smaller vehicles, though airflow and heating costs reflect the booth size.

What should we prepare for a site visit?

Vehicle dimensions, building drawings, door sizes, utility service details and how vehicles move through the depot.
