Air Make Up Units for HVAC Finishing Areas
Finishing areas for HVAC cabinets, fan housings and panels can move a large volume of air through booths, exhaust systems and ovens. Double D Mechanical installs, relocates and connects air make up units so replacement air supports the coating process and the surrounding plant.
Discuss your installationBalancing Exhaust From Booths and Ovens
Powder booths, paint booths and cure equipment can create different exhaust demands during production. Make up air planning should account for simultaneous operation, fan starts and nearby exhaust sources so the finishing area does not pull uncontrolled air from the building.
Supply Placement Near Production Lines
Replacement air should be introduced without disturbing powder application, wet spray patterns or part cooling. Discharge location, diffuser style and duct routing should be reviewed against conveyors, racks, forklifts and operator work zones.
Tempered Air for Consistent Conditions
Heated or tempered air can help stabilize the finishing environment when outdoor air conditions affect the plant. Fuel or electrical service, intake location and condensate or drain needs should be considered with maintenance access.
Controls and Interlock Coordination
The air make up unit should operate with the equipment it supports. Start signals, fan proving, pressure controls, shutdown behavior and operator panels need to be coordinated with booth and oven controls.
Information for Airflow Review
Gather exhaust fan data, booth and oven information, production schedules, roof or wall options, utility availability and photos of the proposed unit and duct locations before the walkthrough.
Frequently asked questions
Why does an HVAC finishing area need make up air?
Exhaust systems remove air from the building. Planned replacement air helps reduce drafts, door pull and unstable airflow around coating equipment.
Can one unit serve several pieces of finishing equipment?
It may be possible when total exhaust volume, operating modes, controls and duct layout are reviewed as one system.
Where should the unit be located?
Location depends on intake air, discharge path, service clearance, structural support, utility access and the need to avoid production traffic.
What should be ready before a site visit?
Fan data, equipment drawings, utility information, ceiling height, photos and notes about current pressure or draft issues are helpful.
