Illinois Prep Stations Built Around Long Parts and Steady Throughput
In a trailer or truck body plant, the prep step has to keep pace with the line. Rails, crossmembers, landing gear brackets and side panels all need scuffing, cleaning and masking before they see primer, and many of those pieces are long. Double D Mechanical sets up prep stations in Illinois with layouts that match the part length and the flow of work, then connects the exhaust, compressed air, lighting and any heat so the station runs without becoming a bottleneck.

Hyundai Translead's trailer plants in Will County point to how much trailer production activity sits around the Chicago market, and that work drives a specific kind of prep layout. A standard square open-face unit does not fit a long chassis rail. Elongated crossdraft stations with curtains on both ends let a part roll through on a cart, get prepped along its full length and exit toward the booth without being turned around. Filter walls get sized to the face area, which grows quickly as the station gets longer.
Matching the Station to Primer and Sanding Loads
Dry sanding produces heavy, coarse dust that loads filters fast. Primer and sealer add sticky overspray. A station that does both needs a filter arrangement that handles each without choking airflow halfway through the week.
- Pre-filter layers sized for sanding dust so final media lasts longer
- Manometer or pressure gauge visible to the operator so filter changes happen on time
- Access doors placed where filter swaps do not require moving parts out of the way
- Exhaust fan selected with enough static pressure margin for loaded filters
Fitting a Station Into an Existing Chicago-Area Plant
Most prep station projects happen in buildings that are already running. That means routing duct around cranes, sprinkler mains and conveyor supports, cutting roof or wall penetrations without shutting down neighboring departments, and scheduling tie-ins for weekends or shift gaps. We map the route with your maintenance team before anything is ordered so the duct, fan and discharge fit the building as it actually is.
Service After Startup
Once the station is in, the maintenance items are predictable: filters, fan belts and bearings, curtain condition, light lens cleaning and checking that the exhaust still pulls what it did on day one. We can service stations we installed and ones that came with the building, including rebalancing airflow when a new booth or oven changes the building pressure.
Planning a booth or oven project in Illinois
Crews mobilize from Houston; Illinois is roughly 950 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Illinois is concentrated around Chicago, Peoria, Rockford, and Champaign. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include heavy equipment and machinery, food processing, metal fabrication, and transportation equipment.
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
How long can a prep station be?
Length is set by the parts and the floor space. Longer stations need more filter face area and a larger fan, so the practical limit is often the exhaust volume the building can replace with make-up air.
Can trailers or truck bodies be prepped in a drive-through station?
Yes. Drive-through prep stations with doors or curtains at both ends are common for complete units. The exhaust and lighting layout has to account for the full height and width of the vehicle.
Do you handle the duct penetration through the roof?
We plan and install the exhaust duct and discharge. Roof curbing and flashing are coordinated with your roofer when the building warranty requires it.
What should we measure before calling about a prep station?
Measure the longest and tallest part, the clear floor area, ceiling height to the lowest obstruction, and note where the nearest exterior wall or roof access is. That covers most of what is needed to start a layout.
Can a prep station have heat for primer cure?
Heated prep stations use a make-up air unit or recirculating heater to raise the temperature for flash and cure. Gas, controls and interlocks are added to the install scope when heat is included.
