Spray-Tech/Junair booths for collision repair
Spray-Tech/Junair equipment includes downdraft, crossdraft and automotive refinish booths used in collision repair work. Double D Mechanical installs, relocates and services these booth systems while coordinating vehicle flow, airflow, exhaust, make-up air and utility connections.

Plan around vehicle movement
Collision repair booths need clear approach space for damaged vehicles, repaired panels, carts, masking materials and painter access. Placement should consider door swing, booth entry, adjacent prep areas and where vehicles move after paint without crossing dusty work zones.
Control draft and replacement air
Downdraft and crossdraft booths rely on predictable airflow through the cabin. Exhaust fans, intake filters, heated make-up air and building pressure should be reviewed together, especially when the booth is near overhead doors, wash areas or other exhaust systems.
- Confirm intake and exhaust paths before roof or wall openings are made.
- Protect booth air from sanding dust and shop traffic.
- Leave service access to fans, filters, dampers and controls.
Coordinate utilities before assembly
Electrical power, lighting, control wiring, compressed air, gas piping and fire protection interfaces all affect booth operation. Early coordination helps avoid blocked panels, inaccessible junctions and duct conflicts after the booth structure is set.
Service clues worth documenting
Before a service visit, note symptoms such as weak airflow, uneven heat, unusual fan noise, filter loading, lighting issues or control faults. Photos of the booth, mechanical equipment and nameplates help narrow the field work needed on arrival.
Frequently asked questions
What information helps place a collision repair booth?
Vehicle size, booth footprint, door swing, ceiling height, roof structure, utility routes, prep area layout and maintenance clearances are all useful.
Why can a booth feel different after being moved?
A new location can change duct length, exhaust resistance, make-up air supply and surrounding pressure conditions, which can affect airflow and cure performance.
Should prep work be directly beside the booth?
Prep work can be nearby, but dust control and traffic flow matter. Intake air should be kept away from sanding dust and overspray from other operations.
What access should remain open after installation?
Keep room for filter changes, fan service, burner access, light service, control panels and inspection of ductwork or dampers.
