Automotive Booth Air Make-Up Unit Installation
An air make-up unit helps an automotive paint booth replace the air removed by exhaust fans. Double D Mechanical coordinates unit placement, duct routing, heat, gas, electrical service, controls and access so the booth and surrounding shop can maintain a workable air balance.

Paint booth exhaust can remove a large amount of air from the building. The make-up air unit has to be planned with the booth exhaust rate, booth type, intake arrangement and nearby shop spaces in mind. Proper coordination helps avoid hard-opening doors, drafts through prep areas and inconsistent booth conditions.
Unit Location And Duct Alignment
Make-up air equipment may be placed on the roof, at grade or in another suitable mechanical location depending on the building and equipment design. Installation planning should review roof curbs, structural support, duct path, weather exposure, service clearance and how the unit connects to the booth plenum or supply path.
Gas, Power And Control Interlocks
Heated make-up air requires close coordination of gas piping, electrical feeds, disconnects, sensors and control wiring. Interlocks between exhaust fans, booth controls and the make-up air unit should be laid out before field work begins so trades can sequence their work cleanly.
Walkthrough Preparation
Before a site visit, gather booth information, exhaust fan data if available, building measurements, roof access notes, utility locations and preferred equipment placement. Photos of the roof, mechanical room, booth ceiling and exterior wall options can make the review more useful.
Frequently asked questions
Why does an automotive booth need make-up air?
The booth exhausts air from the building, and replacement air helps maintain booth performance and pressure balance in nearby work areas.
Where can an air make-up unit be installed?
Placement depends on the equipment and building conditions, including roof structure, duct routing, service access and utility locations.
What utilities are involved?
Common items include electrical service, control wiring and gas piping for heated units, along with duct connections to the booth or supply plenum.
What should be checked before installation?
Review the booth exhaust needs, available utilities, roof or wall routes, service clearances, control locations and sequencing with other trades.
