Air Make-Up Units for Fleet Maintenance
Fleet maintenance facilities that paint or refinish vehicles need make-up air coordinated with booth exhaust, large doors and service bay activity. Double D Mechanical installs, relocates and services air make-up units while planning ductwork, utilities, controls, roof openings and maintenance access.
Discuss your installationReplacement Air for Large Vehicle Bays
Fleet shops often have tall doors, long vehicles and open service areas that affect building pressure. A make-up air unit should be reviewed with booth exhaust, door operation and nearby service bays so airflow remains stable during paint operations.
Duct Routing Above Active Shops
Ductwork, diffusers and unit supports must fit around lifts, cranes, lighting, fire protection, overhead doors and vehicle clearance. Planning the route early helps protect both service access and day-to-day shop movement.
Utility Tie-Ins and Trade Sequence
Installation can involve gas piping, electrical service, controls, roof curbs, duct supports and coordination with booth equipment. Sequencing with roofing, electrical and mechanical trades helps keep the work organized around an operating facility.
Maintenance Access for Facility Staff
Filters, motors, burners, dampers, belts and controls should remain reachable after installation. Access paths should account for ladders, platforms, roof approach and areas where vehicles may be parked.
- Document booth exhaust and operating modes.
- Show overhead doors and tall vehicle paths.
- Mark existing gas, power and control locations.
Frequently asked questions
Why is fleet vehicle size important?
Vehicle height and length affect booth selection, duct routing, door clearances and where equipment can be serviced.
What building features should be reviewed?
Overhead doors, roof structure, lifts, lighting, fire protection, utilities and existing ventilation should be reviewed.
Can make-up air work be planned around an active shop?
Yes. Access, sequencing and tie-in points should be reviewed so work can be coordinated around facility operations.
What documents help with planning?
Shop layouts, booth data, unit information, roof drawings if available and utility locations are useful.
