Blowtherm USA Paint Booth Exhaust Ductwork
Blowtherm USA paint booth exhaust ductwork must be planned as part of the booth air system, not just as sheet metal from one point to another. Downdraft and automotive refinish booth layouts depend on a clear exhaust path, suitable fan access, coordinated make-up air and a building route that does not interfere with production or maintenance.

Duct Route and Building Constraints
The exhaust route should be checked against roof structure, wall openings, overhead doors, cranes, sprinkler piping, lighting and nearby equipment. A route that avoids one conflict may create another at the fan, stack, service platform or discharge point.
Fan Placement and Maintenance Reach
Exhaust fans need room for installation, vibration review, belt or motor access and future service. Supports, transitions, dampers and cleanout points should be considered before finalizing the duct layout.
Balancing Exhaust With Replacement Air
When exhaust changes, make-up air and building pressure should be reviewed at the same time. An imbalance can affect booth clearing, door movement, temperature stability and the way air moves from nearby shop areas.
Field Review Checklist
Before the site visit, gather photos of the booth exhaust outlet, fan, duct route, roof area, make-up air unit and any damaged or modified duct sections. Note recent filter changes, fan noise, pressure complaints or changes to nearby ventilation.
Frequently asked questions
Why review make-up air during exhaust ductwork work?
Exhaust removes air from the booth, and make-up air replaces it. If they are not coordinated, booth pressure and airflow can become unstable.
What ductwork issues can affect booth performance?
Restrictions, leakage, damaged transitions, fan problems, poor supports and unsuitable discharge routing can all affect performance.
What access is usually needed for exhaust ductwork?
Access may be required inside the booth, above the booth, at the fan, on the roof or at an exterior wall discharge point.
What should be documented before ductwork repair or modification?
Document the current route, fan nameplate, roof or wall penetration, make-up air unit, visible damage and any operational symptoms such as slow clearing or vibration.
