Paint Manager Jake Brewer standing in front of Duncan Aviation’s new paint hangar in Provo, Utah. The hangar is 53,000-square-feet and has a two-zone air system featuring a down-draft airflow and automatic monitoring and alarms. It is the only truly green business aviation paint facility in the United States. No waste products are released into the water or city and more than 99.7% of the air released is clean due to an RTO (Regenerative Thermal Oxidizer) that burns off the VOCs (Volatile Organic Compounds).
