Spray Booth Airflow Systems Explained: Downdraft vs Crossflow vs Semi-Downdraft
A Spray Booth is an essential part of many automotive, industrial, and manufacturing environments across Australia where high-quality finishing, safety, and controlled working conditions are required. The airflow system inside a booth plays a major role in determining the quality of the final coating, the efficiency of the painting process, and the protection of workers from airborne particles and fumes. Understanding how different airflow designs work helps businesses select the right solution for their specific applications. When choosing an airflow system, three common designs are widely considered: downdraft, crossflow, and semi-downdraft. Each system uses a different method to move air through the working area, remove overspray, and maintain a cleaner environment. The ideal choice depends on factors such as the type of work being completed, available space, production requirements, and the desired finish quality. This guide explains the differences between these systems and ...
