Air Make Up Units for Truck Body Finishing
Truck body paint booths, prep areas, blast rooms, and exhaust systems remove large amounts of air from the building. Double D Mechanical installs, relocates, and services air make up units that replace exhausted air and help support stable airflow around long bodies, frames, panels, and coating operators.
Discuss your installationReplacement Air for Large Paint Areas
A truck body finishing area may include a booth, prep station, mix room, exhaust fans, and dust collection equipment operating in different combinations. The make up air system should be planned around the actual operating sequence so replacement air supports capture without pulling dust through doors or across wet finishes.
Discharge Paths That Avoid Draft Problems
Where air enters the building matters as much as the unit size. Duct drops, diffusers, discharge velocity, and unit placement should be arranged so air does not blow directly across spray zones, masking work, open parts, or operators working beside tall bodies.
Heating, Fuel, and Controls
Tempered replacement air can improve working conditions and reduce temperature swings around the coating process. Installation planning may include gas piping, electrical service, control wiring, fan interlocks, intake openings, discharge duct, and coordination with existing booth controls.
- Gather exhaust fan data for booths, prep stations, and blast equipment.
- Review roof or wall placement along with structural support and access.
- Confirm whether the unit will serve one process area or several finishing zones.
Filter and Service Access
Air make up units need practical access for filter changes, belt or motor service, burner service, and control inspection. The unit location should avoid blocking truck body staging, overhead doors, cranes, and maintenance aisles that keep production moving.
Frequently asked questions
Why does a truck body booth need make up air?
Booth exhaust removes air from the building, and replacement air helps reduce pressure problems, drafts, dust movement, and unstable spray conditions.
Can one unit serve a booth and prep station?
It may be workable if airflow demand, duct layout, controls, and operating schedules are reviewed together.
What are signs of poor air balance?
Doors pulling hard, odor movement, cold drafts, dust crossing work areas, and inconsistent booth capture can point to air balance issues.
What information helps size the installation?
Exhaust fan data, booth dimensions, operating sequence, building openings, utility availability, and production flow are important starting points.
Can an old unit be replaced in the same location?
Sometimes, but roof support, curb condition, duct connections, gas or electrical service, controls, and service clearance should be checked first.
