Air Make-Up Units for Collision Repair
Collision repair paint booths need replacement air that supports booth balance, temperature control and reliable exhaust. Double D Mechanical installs, relocates and services air make-up units for refinish areas, coordinating ductwork, gas or electrical utilities, controls, roof openings and access for maintenance.
Discuss your installationBalancing Booth Exhaust
A paint booth exhausts a large volume of air during spray and cure cycles. The make-up air unit should be reviewed with booth airflow, building pressure, door openings and adjacent repair bays so the booth is not starved for air.
Placement Around Shop Operations
Collision repair shops need clear movement for vehicles, parts carts and technicians. Unit location, duct drops, diffusers and service panels should be placed so they do not interfere with booth doors, mixing rooms, prep areas or estimating lanes.
Utilities and Controls for Refinish Areas
Installation may require gas piping, electrical service, low-voltage controls, duct supports, roof curbs and coordination with booth controls. Sequencing these items with roofing, electrical and mechanical trades helps avoid rework during booth startup.
- Confirm booth operating modes and airflow needs.
- Identify roof structure and curb locations early.
- Keep filter and burner access reachable.
Information for the First Review
Prepare booth make and model information if available, shop layout, ceiling height, roof access, utility locations, current comfort complaints and photos of the booth, roof area, ductwork and mechanical room.
Frequently asked questions
Why does a collision shop need make-up air?
Booth exhaust removes air from the building, and replacement air helps maintain booth performance and shop pressure.
Can a make-up air unit serve more than one booth?
That depends on the booth airflow, controls, operating modes and duct layout, which should be reviewed before planning.
What access is needed for service?
Filters, burners, motors, belts, dampers, controls and roof or platform access should remain clear.
What photos help before a visit?
Photos of the booth, roof, existing unit, ducts, control panels and utility points are helpful.
