Overview

Fresh Air Handling Unit (FAHU) is a specialized air handling unit (AHU) designed to supply 100% fresh, filtered, and conditioned air into a building. Unlike standard AHUs that recirculate indoor air, FAHUs are dedicated to improving indoor air quality by continuously bringing in outdoor air, removing contaminants, and maintaining optimal temperature and humidity levels.
