Garmat USA Paint Booth Exhaust Ductwork
Garmat USA paint booth exhaust ductwork has to move air from the booth to the discharge point while preserving booth performance, building pressure and service access. For downdraft, semi-downdraft, automotive refinish booth and prep station layouts, Double D Mechanical reviews the booth connection, duct route, fan placement, supports and make-up air interface before field work begins.

Path From Booth Connection to Outlet
The duct route should be planned around the booth outlet, roof or wall penetrations, structural members, overhead doors, cranes, lighting, sprinkler piping and adjacent production lines. Shorter routes are not always simpler if they block service access or create conflicts above the booth.
Fan Service and Support Points
Fans, transitions, stacks and supports need space for installation and later maintenance. Access for belts, bearings, motors, dampers and cleanout points should be considered before the duct route is fixed. Existing roof curbs, wall openings and support steel should be checked for condition and fit.
Make-Up Air Interaction
Exhaust changes can affect booth pressure, door behavior, overspray control and temperature stability. If make-up air is undersized, poorly timed or routed into the wrong part of the room, the booth may struggle even when the ductwork is physically intact. Exhaust work should be coordinated with the air make-up unit, controls and building ventilation.
Information Needed in the Field
Before a site visit, gather booth dimensions, exhaust outlet locations, fan nameplate photos, roof access details and any recent changes to filters, doors or make-up air. Photos of the roof, ceiling space and nearby equipment help identify lift needs, shutdown constraints and possible trade conflicts.
Frequently asked questions
When should Garmat USA booth ductwork be reviewed?
Review is useful when airflow changes, fans vibrate, duct sections are damaged, roof penetrations leak, the booth is being moved or production changes require a different discharge route.
Can exhaust ductwork affect booth pressure?
Yes. Restrictions, leakage, fan issues and make-up air imbalance can change booth pressure and airflow patterns, which may affect overspray control and door behavior.
What access is needed for ductwork work?
Access may be needed inside the booth, above the booth, at the fan and on the roof or exterior wall. Clear aisles and lift routes should be available before field work starts.
What should be photographed before a ductwork visit?
Helpful photos include the booth outlet, fan, duct route, roof penetration, stack, make-up air unit, control panel and any damaged or modified duct sections.
