Air Make Up Unit Installation for Industrial Paint Booths
An air make up unit replaces the air removed by a paint booth exhaust system and helps stabilize booth balance, building pressure and operator comfort. Double D Mechanical installs and connects air make up units for industrial finishing areas, coordinating placement, ductwork, utility connections, controls and service clearances.
Discuss your installationBalancing Booth Exhaust Demand
Paint booth exhaust removes a significant volume of air from the building. The air make up unit must be planned around booth style, exhaust volume, filter loading, door openings and the pressure needs of nearby production areas. Poor balance can affect overspray control, door operation, temperature stability and drafts around the booth.
Unit Location and Duct Paths
The unit location affects structural support, roof or grade access, duct routing and service reach. Installation planning reviews where supply air enters the booth or shop, how ductwork crosses the building, and whether the route conflicts with cranes, sprinklers, busways, lighting, mezzanines or other equipment.
- Verify roof, curb, pad or platform requirements before setting equipment
- Keep service doors, filters, burners and controls accessible
- Coordinate penetrations with existing structure and weatherproofing work
Fuel, Electrical and Controls Coordination
Air make up equipment may require gas, electrical service, control wiring and interlocks with booth exhaust or booth controls. Connection planning should identify shutoff locations, panel space, disconnect access and the control sequence needed for startup, shutdown and production modes.
Start Up Preparation and Site Readiness
Before installation, it helps to gather booth drawings, exhaust fan information, building utility data, structural constraints and photos of the intended equipment location. Clear staging space and confirmed access for lifting equipment can reduce surprises when the unit, curb, duct sections and controls arrive.
Frequently asked questions
Why does a paint booth need make up air?
The exhaust system removes air from the building, and make up air replaces it so booth airflow and building pressure remain more stable.
Where can an air make up unit be installed?
Placement may be on a roof, exterior pad, platform or indoor mechanical area, depending on the building, duct route, utility access and service clearances.
Does the air make up unit connect to the booth controls?
It often needs to be coordinated with exhaust and booth operation so airflow is available when the booth is running and shut down in the proper sequence.
What should be checked before installation?
Key items include exhaust requirements, unit dimensions, structural support, gas and electrical capacity, duct route, access for lifting and space for future service.
