Air Make-Up Units for Defense and Military Depots
Defense and military depot finishing areas may support vehicles, components, ground equipment and aircraft-related work with significant exhaust demand. Double D Mechanical installs, relocates and services air make-up units that help stabilize air replacement for booths, hangars, blast areas and ovens while coordinating ductwork and utilities.
Discuss your installationReplacement Air for Depot Finishing Areas
Depot work can include large parts, mixed equipment sizes and controlled shop areas. Air make-up planning should consider the exhaust load from paint booths, blast equipment, cure equipment and prep spaces so nearby doors, corridors and work areas are not affected by large pressure changes.
Mechanical Routing in Secure Shop Layouts
Duct and equipment routes may need to work around existing utilities, cranes, door clearances, platforms and building access limits. A practical layout keeps intake locations, discharge points, filter sections and fan service areas reachable while respecting the flow of vehicles, parts and maintenance equipment.
Controls, Heat and Trade Sequencing
Power, fuel, control wiring, dampers and interlocks should be sequenced with electrical and building work before startup. Double D Mechanical coordinates the mechanical installation around the connected finishing equipment so the air make-up unit operates with the exhaust systems it serves.
Information for Depot Walkdowns
Before a site visit, gather available drawings, equipment submittals, exhaust fan data, utility locations, roof access details and notes on areas with restricted entry. Photos of existing ventilation equipment and surrounding clearances help narrow the installation approach.
Frequently asked questions
What does an air make-up unit support in a depot finish shop?
It replaces air removed by exhaust systems serving paint, prep, blast or cure equipment, helping the building maintain steadier pressure during operation.
What clearances matter most around the unit?
Plan for access to filters, fans, dampers, heat sections, controls and panels, plus rigging space for installation or future service.
Can a unit be tied to more than one exhaust system?
It can be reviewed when airflow demand, duct routing and controls are known. The systems that run at the same time are especially important.
What should be ready before relocation planning?
Have the existing unit information, duct drawings if available, utility locations, roof opening details and the intended new operating sequence.
