Paint Booths and Powder Lines for Indiana Furniture Makers
Indiana furniture and fixture plants are frequently housed in large single-story buildings that have changed hands and products more than once. That gives room to work with, but it also means the finishing area may have grown in pieces, with a booth here, a sanding line there, and duct runs nobody has traced in years. When we look at a finishing room in a plant like that, the first job is sorting out what each piece of equipment is doing to the building's air, then deciding what to keep, what to move and what to add.

Sanding dust is the most common reason a wood finish fails inspection. If the sanding line and the spray booth share the same open room, the booth's exhaust fan pulls that dust straight toward the wet parts. We look at the pressure relationship between the two areas, where the dust collector discharges or returns air, and whether a wall, curtain or relocated booth can put the spray area on the clean side of the building's airflow.
Open-Face Booths for Case Goods
Dressers, cabinets, desks and store casework are usually sprayed on turntables or carts in front of an open-face booth. Those booths are simple, but they work only when face velocity is even across the opening and the room in front of them has enough replacement air. A booth that starves for air will pull dust from doors and dock openings. We size the replacement air path along with the booth fan so the whole room stays balanced.
- Turntable and cart positions set for operator reach
- Filter banks accessible without moving parts out of the way
- Lighting placed to show finish defects on large flat surfaces
Heated Replacement Air Through the Cold Months
Every cubic foot a booth exhausts has to come back into the building. In an Indiana winter, that air arrives cold unless it is heated, and cold replacement air slows drying and can leave operators working in a draft. A dedicated heated make-up unit, interlocked with the booth fan, keeps the finish room at a workable temperature. We plan the unit's location, gas service, duct path and controls together so the booth cannot run without its air.
Relocating a Line Within the Plant
When production changes, finishing often has to move. Moving a booth or powder line a few hundred feet sounds simple until the exhaust stack, roof curb, gas line and conveyor supports all have to follow it. We document the existing installation, plan the new location's roof and floor work, and sequence the move so disconnection, transport and reconnection happen in the shortest possible shutdown.
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 does our finish pick up dust even with new filters?
Usually the booth is pulling dirty air from somewhere it should not, often a sanding area or an open dock door. Balancing replacement air with exhaust generally fixes it.
Can a powder line and a liquid booth share one building?
Yes, provided powder overspray and liquid overspray are kept in separate enclosures and each has its own exhaust or recovery path.
How do we plan a booth move without losing weeks of output?
By preparing the new location first: roof penetrations, curbs, gas and electrical rough-in done ahead of the move so only disconnect, transport and hookup happen during the shutdown.
Does make-up air need to be interlocked with the booth fan?
It should be. An interlock keeps the booth from running against a closed or unheated air path, which protects both finish quality and the building's pressure balance.
