Side Downdraft Paint Booth Installation

Low Side Exhaust Planning

Side downdraft booths rely on side plenums to pull air down and away from the workpiece. The booth footprint must allow room for those plenums, filter access and duct connections. This can be useful where cutting a full pit is not practical, but it still requires careful mechanical layout.

Ceiling Intake and Air Balance

Uniform intake air helps maintain consistent spray conditions from one end of the booth to the other. Filter loading, air unit placement, duct transitions and building pressure can change how the booth behaves during production. Make-up air should be sized and located with the exhaust system in mind.

Material Handling Around the Booth

Side downdraft booths are used for vehicles, components and fabricated assemblies that need controlled airflow with manageable floor requirements. Door approach, cart clearance, lift access and aisle width should be checked against the largest expected workpiece.

Installation Sequencing

The booth shell, side plenums, exhaust ducts, fans, air unit, controls and utilities all need to land in the right order. Double D Mechanical coordinates mechanical installation with electrical, roofing, structural and fire protection work so access and alignment issues are addressed early.

• Confirm clearance beside side plenums before placing adjacent equipment.
• Review roof curb locations before duct sections are lifted into place.
• Keep service panels and filter doors clear of storage and traffic.
