Air Make Up Units for Heavy Equipment Finishing
Paint booths, blast rooms and finishing areas for heavy equipment move a lot of air. Double D Mechanical installs, relocates and services air make up units so exhaust systems, booth pressure, heating needs, duct routing and service access are considered together instead of as separate problems.
Discuss your installationBalancing Booth Exhaust Demand
Large equipment booths and blast enclosures can exhaust enough air to affect adjacent spaces, doors and nearby processes. Make-up air planning looks at where air enters, how it reaches the booth opening or plenum and whether the finishing area stays stable while equipment is running.
Heated Air and Production Conditions
When finishing work needs tempered air, the unit location, burner or heat source, controls and discharge arrangement all matter. Heavy frames and thick weldments may not need the same room conditions as smaller parts, but the operators and coating process still need a predictable environment.
Duct Routes and Roof Openings
Air make up units may sit indoors, outdoors, on a roof or at grade depending on building structure and service access. Installation planning includes duct supports, roof curbs, wall penetrations, intake location, discharge path and coordination with exhaust stacks.
Controls With Booth Operation
The make-up air unit should operate in step with the booth or blast process it supports. Interlocks, starters, temperature controls and shutdown behavior need to be coordinated with the finishing equipment and electrical trade.
Site Details That Help Sizing Review
Before a walkthrough, gather the information that shows the air system load and building limits.
- Booth or blast enclosure exhaust requirements
- Current heat source and available utilities
- Preferred unit location and access route
- Roof structure or outdoor pad constraints
- Nearby doors, louvers and occupied work areas
Frequently asked questions
Why does heavy equipment finishing need make-up air?
Exhaust fans remove air from the building. A make-up air unit replaces that air so booth airflow, room pressure and operator conditions remain more predictable.
Can one unit serve more than one finishing area?
Sometimes, but the layout, controls, simultaneous operation and duct routing need to be reviewed so one process does not starve another of air.
Where can an air make up unit be installed?
Common options include roof mounting, outdoor pad mounting and indoor mechanical space placement, depending on structure, weather exposure, service access and duct routing.
What trades are usually involved?
Mechanical, electrical, roofing, structural and controls work may all need sequencing around the unit, duct, intake, discharge and fuel or power connections.
What should remain accessible after installation?
Filters, belts, burners, dampers, motors, controls and access panels should remain reachable without blocking production movement.
