Charleston Air Force Base houses the 437th Airlift Wing, the unit responsible for flying and maintaining the C-17 Globemaster III. The 77,000 SF Corrosion Control Facility/Paint Hangar is designed to move air horizontally across all portions of the aircraft surface at a minimum of 75 feet per minute, utilizing a near laminar horizontal airflow, from nose to tail of the C-17 aircraft. An exhaust system removes paint fumes and filters paint particulate in accordance with the latest environmental regulations.

The DDC control system, which automatically adjusts fan supply and exhaust, provides a constant air volume and velocity over all surfaces undergoing the paint application process.

The HVAC system is computer controlled to maintain a minimum temperature at all times in the paint dock. In addition, sophisticated fan speed controls maintain a precise static pressure inside the paint dock relative to the adjacent areas and the exterior of the facility.
