Paint Booth Exhaust Ductwork for Air Make-Up Units
Paint booth exhaust ductwork and air make-up units have to work together so the booth can remove contaminated air while receiving controlled replacement air. Double D Mechanical installs and relocates exhaust ductwork with attention to fan paths, intake and discharge locations, controls, utilities, clearances, and service access around air make-up equipment.
Discuss your installationMatching Exhaust To Replacement Air
The exhaust system removes air from the booth or finishing area, while the air make-up unit brings replacement air back into the process. Planning both sides together helps maintain stable booth pressure, temperature control, and predictable airflow direction.
Duct Routing Between Equipment
Exhaust ducts, supply ducts, fans, intakes, stacks, and curbs often compete for roof and ceiling space. Routes should be reviewed for structural support, weather exposure, access platforms, existing rooftop units, and interior obstructions.
Controls, Interlocks, And Utilities
Electrical feeds, gas service, control wiring, dampers, and fan operation may need to be sequenced so the booth and make-up air equipment operate together. Coordination with electrical, gas, controls, and fire protection trades should happen before installation work begins.
Service Space Around Units
Filters, burners, motors, belts, dampers, access doors, and control panels need room for inspection. Ductwork should not block panels or create service paths that require removal of unrelated equipment.
Site Details To Bring Forward
Before a site visit, gather booth drawings, air make-up unit information, fan data, roof plans if available, utility locations, photos of equipment areas, and notes on operating windows or production restrictions.
Frequently asked questions
Why should exhaust ductwork be coordinated with an air make-up unit?
The booth exhaust and replacement air system affect the same pressure and airflow conditions, so they should be reviewed together for stable operation.
Can a new air make-up unit change the exhaust ductwork plan?
Yes. Unit location, supply duct routing, controls, and roof space can affect exhaust fan placement, duct paths, and service clearances.
What utilities are usually reviewed?
Common items include electrical feeds, gas service, control wiring, dampers, fan power, and any interfaces with booth safety systems.
What access should remain around air make-up and exhaust equipment?
Access should remain for filters, burners, fans, motors, belts, dampers, control panels, cleanout points, and roof or wall discharge components.
What information helps Double D Mechanical evaluate the site?
Useful information includes equipment drawings, current duct photos, roof access details, utility locations, fan information, and notes about production areas that need to stay open.
