Marathon downdraft paint booth installation and relocation
Marathon downdraft paint booths move air from the ceiling toward the floor area to support controlled finishing for vehicles and equipment. Double D Mechanical plans installation, relocation and connections around floor openings or exhaust plenums, air replacement, heat, lighting, controls and maintenance access.

Floor System and Booth Footprint
Downdraft booth placement is tied closely to the floor. Pit dimensions, raised basement sections, grating, drain locations and slab conditions can affect the set location. The layout should also leave clear approach space for vehicles, racks or equipment entering the booth.
Ceiling Supply to Lower Exhaust
A downdraft arrangement depends on clean supply air entering overhead and moving through the work zone before leaving below. Supply plenums, filters, exhaust chambers, fan connections and duct paths should be reviewed together so the booth is not treated as only an enclosure.
Air Replacement, Heat and Controls
Make-up air equipment, heat sections, electrical service and controls need coordinated locations. Access to filters, dampers, burners, control panels and disconnects should be preserved so routine service does not require moving shop equipment.
Information to Bring to the Walkthrough
A useful site review starts with booth drawings, floor details, utility locations, photos, part or vehicle dimensions and notes about adjacent processes. For relocation, document duct connections, panel layout, control wiring, fan orientation and any floor components before disassembly.
- Confirm whether the booth uses a pit, basement or other lower exhaust arrangement.
- Identify the route for stacks, supply duct and replacement air equipment.
- Reserve space for filter changes, lighting access and control service.
Frequently asked questions
What is the main planning issue with a downdraft booth?
The floor exhaust arrangement drives much of the layout, including pit work, duct routing, access and vehicle approach.
Can a downdraft booth be relocated?
Yes, but the new area must be reviewed for floor requirements, exhaust path, supply air, utilities and service clearances.
What utilities are commonly involved?
Electrical service, lighting, controls, compressed air, gas for heat and interlocks may need coordination.
Why preserve access around air handling equipment?
Filters, fans, dampers, burners and control panels need periodic attention, and tight access can make service slower.
