All Duroair systems benefit from Taper Draft airflow. Taper Draft works by pulling a high volume of clean air through an intake filter that, once inside the clean room, creates an envelope of airflow over the work piece avoiding any contamination by environmental elements present at site. The air volume is then extracted from the enclosure through a two-stage tapered filter chamber that provides high levels of CFM and air turbulence required for waterborne coatings. A wicking process is created by the air envelope that, effectively, pulls moisture off the work piece and greatly enhances drying times and throughput.
