Air Make Up Units for Aircraft Finishing
Aircraft booths and paint hangars exhaust large volumes of air during coating, sanding and related finishing work. Double D Mechanical installs, relocates and services air make up units that help replace exhausted air, support room balance and coordinate with the mechanical systems serving aircraft and component finishing areas.
Discuss your installationMatching Air Supply to Exhaust Demand
Air make up equipment should be reviewed with the exhaust fans it supports. Hangars and component booths may have different operating modes, so the supply strategy needs to account for airflow demand during coating, prep and idle conditions.
Tempered Air for Large Work Zones
Aircraft finishing spaces can be sensitive to drafts and temperature swings across broad surfaces. Heating, discharge location and duct arrangement should be planned so replacement air supports the process without disturbing spray patterns or technician work zones.
Routing Around Hangar Constraints
Roof structure, door systems, platforms, cranes, lights and existing utilities can all affect where units and ducts are placed. Early layout review helps reduce conflicts before rigging, curb work or penetrations are scheduled.
Controls and Equipment Interfaces
Make up air units may need to coordinate with booth controls, exhaust fans, heat calls, damper positions and shutdown functions. Electrical and control routing should be planned with clear access to panels and disconnects.
Information for the First Review
Useful information includes exhaust fan data, booth or hangar drawings, aircraft envelope details, utility locations and any known pressure or temperature concerns.
- Fan sizes and operating modes
- Preferred unit location and structural limits
- Fuel, power and control panel locations
- Areas reserved for stands, carts and aircraft access
Frequently asked questions
Why is make up air important in aircraft finishing?
It replaces air removed by exhaust systems and helps maintain more stable pressure in large spaces where uncontrolled drafts can affect coating work.
Can one air make up unit serve a hangar and a component booth?
That depends on airflow demand, controls, duct routing and whether simultaneous operation would create pressure or temperature problems.
What affects unit placement?
Structural support, roof or wall access, duct length, hangar doors, service clearance, utility routes and nearby production movement all matter.
What should be checked on an existing unit?
Review capacity, condition, filters, heat source, controls, voltage, gas service and whether service access remains practical.
