Booth Exhaust System Installation
A booth exhaust system carries overspray, vapors, heat, and process air out of the finish area. Double D Mechanical installs booth exhaust components with attention to airflow path, fan placement, duct transitions, roof or wall penetrations, filter access, make-up air balance, and the way production moves around the booth.
Discuss your installationExhaust Path From Booth to Discharge
The exhaust route begins at the booth plenum and continues through ductwork, fan equipment, dampers, supports, and the final discharge point. Each turn, transition, and penetration affects installation access and future service, especially in plants with cranes, mezzanines, low roof steel, or crowded utility corridors.
Matching Exhaust to Booth Airflow
Exhaust has to work with booth intake, make-up air, doors, and the workpiece size. A truck booth, open face booth, or downdraft booth may need a different duct approach than a compact refinish booth. The goal is to support steady air movement without pulling dirt through openings or starving adjacent spaces.
Access for Filters, Fans, and Dampers
Maintenance access should be planned before supports and duct sections are installed. Filters, belts, motors, bearings, access doors, and control devices need reachable locations so routine work does not require dismantling adjacent equipment or blocking key production lanes.
- Confirm filter change clearance on the booth and exhaust side.
- Review fan service space before finalizing duct alignment.
- Keep roof access and weatherproofing needs in the installation sequence.
Preparation for the Installation Visit
Useful items include booth drawings, fan data, roof plans, proposed discharge location, existing duct photos, electrical service information, and make-up air details. Facility teams should also identify shutdown windows, hot work procedures, lift routes, and any areas where production cannot be interrupted.
Frequently asked questions
What does a booth exhaust system include?
It can include exhaust plenums, filters, ductwork, fans, dampers, supports, controls, access doors, and roof or wall discharge components depending on the booth design.
Can exhaust ductwork be routed through an existing opening?
Sometimes, but the opening size, structure, weatherproofing, discharge location, and path to the booth all need to be reviewed before relying on an existing penetration.
How does exhaust affect make-up air?
The more air the booth exhausts, the more replacement air the building or dedicated unit must provide. Poor balance can cause drafts, door pull, temperature issues, and unstable booth airflow.
What should be clear before installation starts?
Lift paths, roof access, booth perimeter, filter service areas, electrical tie-in points, and the proposed duct path should be cleared or marked before crews begin work.
