Side Downdraft Paint Booth Installation

Side Plenum Access And Booth Width

Side downdraft booths need space for exhaust plenums along the lower side walls. Installation planning should verify the finished outside dimensions, filter access, door swing and clearance for operators who work around larger parts. The booth may fit where a full pit is impractical, but the side exhaust components still require careful placement and service room.

Balanced Supply And Lower Exhaust

Overhead supply air should reach the work zone evenly before it is pulled toward the side exhaust banks. Duct transitions, fan placement and make-up air equipment should be coordinated so the booth is not forced to draw air through uncontrolled openings. Maintaining access to filters, dampers and control devices helps the facility keep the airflow system usable after startup.

Workpiece Handling Around The Booth

Side downdraft layouts are used for vehicles, equipment, rail components and fabricated parts where floor excavation may be limited. The booth should be aligned with cranes, carts, forklifts or vehicle lanes so the workpiece can enter without damaging booth doors or side plenums. Clear staging areas also help keep parts and masking supplies away from the exhaust intake face.

• Measure the largest regular workpiece, including fixtures or lift points.
• Check whether side plenums reduce usable aisle or operator space.
• Keep maintenance panels clear of stored parts, ladders and tool carts.

Pre-Installation Coordination Points

Before a site visit, collect the proposed booth footprint, ceiling height, utility locations, slab notes, make-up air plans and any restrictions on roof or wall openings. If other trades are installing fire protection, electrical feeds or gas piping, their routes should be coordinated before the booth enclosure and ductwork occupy the same space.
