Makeup Air Units (AMUs) are engineered to supply a controlled volume of clean, filtered, and heated replacement air to spray booths and industrial facilities, helping maintain balanced airflow, stable booth pressure, and consistent temperature performance throughout the finishing process. By using advanced digital sensors and precision control systems, AMUs continuously monitor and regulate tempered air to minimize temperature stratification and reduce fluctuations that can impact coating application, flash times, and overall finish quality. This controlled air delivery supports improved operational efficiency, more uniform curing conditions, and a cleaner, more reliable production environment. Available in both direct-fire and electric configurations, our AMUs can be tailored to meet the performance requirements, energy demands, and application needs of a wide range of finishing systems.
