Industrial Side Downdraft Paint Booth Installation
A side downdraft paint booth directs air downward and outward toward exhaust plenums along the booth sides. Double D Mechanical installs side downdraft booths for industrial finishing operations that need controlled airflow without always relying on a full floor pit system.
Discuss your installationSide Plenums Shape the Layout
Side exhaust plenums affect the booth footprint, wall clearance, filter access, and how technicians move around the workpiece. The installation plan should account for service doors, sidewall filters, lighting, controls, and enough space to work safely along both sides of the booth.
Airflow Around Large Workpieces
Side downdraft booths are often considered for vehicles, equipment bodies, metal fabrications, and other parts that need airflow moving away from the painter and toward side exhaust points. Tall, wide, or irregular parts can affect the air path, so staging height and fixture placement matter.
Ductwork, Fans, and Make-Up Air
Exhaust ductwork may leave the booth from one or both sides, then route to fans and discharge points through a crowded plant or roof area. Make-up air should be coordinated so supply air supports the intended pattern rather than pushing overspray across the part.
- Confirm side clearance before booth panels are set.
- Plan duct supports around cranes, lights, and overhead utilities.
- Keep filter and plenum access free from racks and stored materials.
Planning Inputs for the Facility Team
Useful inputs include booth drawings, part envelopes, aisle widths, crane or hoist coverage, overhead obstructions, electrical service, compressed air locations, and exterior options for exhaust discharge and air intake.
Frequently asked questions
Why choose a side downdraft booth?
It can provide a downward airflow component while using side exhaust plenums, which may fit facilities where floor pits are difficult or undesirable.
What space should be protected during layout?
Protect side service aisles, door movement, filter access, control panel access, and any route needed for lifts or maintenance equipment.
Can side exhaust ducts route overhead?
They often can, depending on the booth design and building constraints. The route must be checked against structure, cranes, utilities, roof access, and discharge locations.
What should be ready for a site review?
Have drawings, photos, dimensions, utility information, largest part details, and notes on how parts enter, rotate, stage, and leave the booth area.
