Automotive Body and Parts Air Make Up Unit Installation
Automotive finishing areas depend on replacement air to offset booth exhaust, oven exhaust, prep station airflow, and general building pressure changes. Double D Mechanical installs, relocates, and services air make up units and the duct, heat, electrical, and control connections that support coating operations.
Discuss your installationReplacement Air for Finishing Areas
Paint booths, prep stations, powder booths, and ovens all remove air from the building. The air make up unit should be sized and placed as part of the whole finishing area so doors, booth openings, and adjacent work zones do not fight each other during production.
Supply Direction Near Coated Parts
Supply air needs to enter the space without stirring dust, pushing overspray, or cooling parts at the wrong point in the process. Duct layout, diffuser location, and discharge direction should be reviewed against booth intakes, prep areas, hanging racks, and open travel paths.
- Map each exhaust source served by the replacement air plan.
- Review heated air needs for cold-weather production and part comfort.
- Keep filter doors, burner access, panels, and roof service points reachable.
Heat, Controls, and Interlocks
Air make up units may require gas or electric heat, control wiring, motor power, dampers, disconnects, and signals tied to booth or oven operation. Double D Mechanical coordinates the physical unit placement, duct connections, utility tie-ins, and control interface points with the equipment layout.
Placement on Roof or Floor
Unit location affects duct length, structural support, maintenance access, intake air quality, and the route to the finishing area. Planning should include roof framing, outdoor access, crane or lift approach, wall penetrations, and the location of other rooftop or shop equipment.
Frequently asked questions
Why does an automotive finishing area need replacement air?
Exhaust systems remove air continuously during coating, prep, or cure. Replacement air helps maintain predictable pressure and supports booth and oven operation.
Can one air make up unit serve multiple pieces of equipment?
It can in some layouts, but the connected exhaust loads, controls, operating modes, duct routes, and pressure behavior should be reviewed together.
What information helps with unit planning?
Provide exhaust equipment drawings, proposed unit location, available utilities, roof or wall details, operating schedule, and the finishing area layout.
What service access should be kept open?
Plan for access to filters, belts or drives, burners, dampers, motors, panels, disconnects, gas train components, and outdoor service paths.
