Garmat USA semi downdraft paint booth installation and service
Garmat USA semi downdraft paint booths are used where finish quality, shop flow and controlled exhaust need to work together without the full pit arrangement of a downdraft booth. Double D Mechanical installs, relocates and services paint booth systems with attention to airflow balance, duct routing, make-up air, gas or electrical utilities, access clearances and coordination with surrounding production areas.

Airflow path and booth placement
A semi downdraft booth pulls filtered air from the upper front or ceiling area and moves it toward rear or low exhaust sections. Placement affects overspray capture, door swing, vehicle movement and nearby prep or masking work. The booth layout should account for the largest expected workpiece, painter movement, staging at both ends and a clean path for intake air.
- Confirm workpiece length, height and door clearance before layout decisions.
- Keep intake paths away from grinding dust, open exterior doors and traffic lanes.
- Plan space for filter service without blocking production flow.
Exhaust, stacks and make-up air
Booth performance depends on the exhaust fan, duct route, discharge location and replacement air working as one system. A relocation or new installation should review roof or wall penetrations, duct support, fan access, weather caps and any heated air unit connections. Make-up air needs enough capacity and distribution to avoid negative building pressure and unstable booth draft.
Utility coordination before setting equipment
Paint booths commonly require electrical feeds, controls, lighting circuits, compressed air, gas piping for heat and connections between booth panels, fans and control packages. Sequencing matters because booth panels, ductwork, fire protection work and electrical rough-in often compete for the same overhead space. Clear interface points help reduce rework once the booth is assembled.
Service access and inspection readiness
A semi downdraft booth should be arranged so filters, belts, bearings, motors, dampers, light fixtures and control panels can be reached safely. Before a site visit, have the booth drawings, ceiling height, roof structure information, utility locations and photos of the intended area ready. If the booth is being moved, note any missing panels, damaged hardware or disconnected controls.
Frequently asked questions
What makes a semi downdraft booth different from a full downdraft booth?
A semi downdraft booth moves air from an upper supply area toward rear or lower exhaust points, while a full downdraft booth typically pulls air down through the floor or pit area. That difference affects floor work, exhaust routing and booth placement.
Can an existing Garmat USA semi downdraft booth be relocated?
Relocation may be possible when the booth can be disassembled, transported and reinstalled with the required panels, fans, controls and utility connections intact. The existing condition and new site layout should be reviewed before work is planned.
What should be checked before connecting exhaust ductwork?
Check fan orientation, duct size, support locations, roof or wall penetration points, discharge direction and service access. The duct route should avoid conflicts with structure, sprinklers, lights and other overhead trades.
Why does make-up air matter for a paint booth?
The booth exhaust removes a large amount of air from the building. Replacement air helps keep booth draft stable, reduces door pull and supports consistent overspray capture.
What information helps prepare for a booth site visit?
Useful items include booth model information, drawings if available, photos of the current or planned location, building dimensions, utility locations, roof details and the largest workpiece expected in the booth.
