Air Make-Up Units for Trailer Finishing
Trailer paint and prep areas often exhaust large volumes of air while long frames, bodies, ramps, doors, and subassemblies move through the finishing process. Double D Mechanical installs, relocates, and services air make-up units and the duct, heat, control, and utility connections that support stable booth operation.
Discuss your installationReplacement Air for Trailer Booths
Paint booths, blast rooms, and exhaust systems can pull enough air from a trailer facility to affect doors, drafts, burner performance, and nearby work areas. A make-up air unit should be matched to the operating sequence of the finishing equipment so replacement air enters the building in a controlled way instead of through gaps, dock doors, or adjacent departments.
Discharge Layout and Part Movement
Trailer workpieces need room for forklifts, carts, cranes, and staging lanes. Ductwork and discharge openings should be placed so they do not interfere with trailer length, lift points, door swing, or inspection access. Air should support the booth or prep area without creating unwanted movement across wet coating, masking, or touch-up work.
- Review trailer path, staging space, and turning clearance.
- Confirm exhaust equipment served by the replacement air system.
- Reserve access for filters, belts, motors, burners, dampers, and controls.
Heat, Utilities, and Controls
Heated make-up air can help the finishing area remain more consistent during seasonal changes. Installation planning should address electrical power, fuel piping where applicable, control wiring, equipment interlocks, intake placement, discharge duct, roof supports, and any structural work needed for the selected location.
Ready Details for the Walkthrough
Before a site visit, gather booth and fan drawings, unit nameplates, current pressure complaints, photos of roof or wall routes, utility locations, and a simple sketch of how trailers enter and leave the finishing area. These details help define conflicts early and keep the installation sequence aligned with production.
Frequently asked questions
Why is make-up air important for trailer painting?
Trailer booths and related exhaust systems remove a large amount of air. Planned replacement air helps reduce uncontrolled drafts and supports more predictable booth airflow.
Can the unit be tied into existing booth controls?
Often the control sequence can be coordinated with booth exhaust and heat operation, but the existing controls, wiring, and equipment condition need to be reviewed first.
Where should discharge air enter the space?
Discharge should be located to support booth balance without blowing directly on wet coating, open booth faces, operators, or masking areas.
What access should be kept open around the unit?
Maintenance staff need clear reach to filters, motors, belts, burners, dampers, gas trains, electrical panels, and control components.
What information helps with relocation planning?
Useful items include unit dimensions, weight, nameplate data, duct sizes, utility routes, crane or lift access, and the layout of the new finishing area.
