Blowtherm USA downdraft paint booth installation and service
Blowtherm USA downdraft paint booths are used where controlled vertical airflow supports vehicle or industrial finishing. Double D Mechanical installs, relocates and services downdraft booth systems with attention to floor openings or pits, exhaust ducting, make-up air, heat, controls, lighting, workpiece clearance and coordination with other trades.

Floor layout and pit coordination
A downdraft booth needs careful planning at floor level because the exhaust path often depends on pits, trenches, raised floors or under-booth plenums. The booth location should be checked against slab thickness, drains, embedded utilities, vehicle path, door swing and the largest expected workpiece. If a booth is moved, the new site may require a different floor approach.
Vertical airflow and replacement air
Downdraft performance depends on air entering cleanly from above and leaving evenly through the floor exhaust path. Exhaust fans, duct static pressure, discharge location and make-up air capacity should be reviewed as a system. Building pressure problems can show up as hard-opening doors, uneven booth draft or poor overspray movement.
- Confirm that overhead supply areas remain clear and serviceable.
- Review duct routes before roof or wall penetrations are selected.
- Plan fan and filter access for routine maintenance.
Utilities and trade sequencing
Downdraft booths can involve electrical feeds, control wiring, lighting circuits, gas piping, compressed air and heat equipment. Installation should be sequenced with concrete work, structural support, roofing, electrical, fire protection and mechanical trades so panels, pits, duct and utilities come together in the correct order.
What to gather before work starts
Useful preparation includes booth drawings, existing equipment photos, slab and roof information, utility locations, ceiling height, fan nameplate data and the intended production flow. For a relocation, identify damaged panels, missing hardware, altered controls or duct pieces that may affect reassembly.
Frequently asked questions
What is the main planning issue with a downdraft booth?
The floor exhaust path is often the largest planning item. Pits, trenches, raised floors or plenums need to match the booth design and the building conditions.
Does a downdraft booth always need make-up air?
A booth that exhausts air from the building needs replacement air to keep airflow stable and reduce building pressure problems. The exact arrangement depends on the equipment and facility.
Can a Blowtherm USA downdraft booth be relocated?
Relocation may be possible when the booth components, fans, controls and floor exhaust arrangement can be adapted to the new site. The new location should be measured and reviewed before teardown.
What utilities are commonly involved?
Common utilities include electrical power, control wiring, lighting circuits, gas piping for heated air, compressed air and connections to exhaust or make-up air equipment.
What service access matters most?
Access to filters, fans, motors, belts, burners, dampers, lights, controls and floor exhaust areas should be preserved so maintenance does not require unnecessary disassembly.
