Elite Finishing Systems

Airflow designs are a defining element of any spray booth, so it’s one of the first things finishing operators need to consider when upgrading to a new booth. While there are only a handful of options when selecting a type of booth, each one carries a unique set of advantages and possible drawbacks. Airflow systems impact every aspect of a booth’s operation, so companies should carefully weigh how their chosen design will affect operating costs, quality of results and workplace safety.

Modified downdraft airflow designs are similar to conventional downdraft systems, resulting in a powerful performance for higher-quality finishes. Compared to conventional downdraft booths, modified downdraft booths have the added benefit of not requiring a pit for installation. However, this means they require additional ductwork to operate efficiently which demands more intensive maintenance and upkeep. Sometimes referred to as a “side downdraft” booth, the term modified downdraft refers to how airflow travels towards the floor before being diverted to side exhaust plenums

Stage 1

Air is drawn through the top of the booth via a ceiling supply plenum and passes through intake filtration comprised of multiple synthetic layers. This ensures that clean air is introduced into the system while providing uniform airflow throughout the booth.

Stage 2

The air continues down and around the product through precisely balanced airflow, collecting overspray along its path and pushing it away from the spray environment. After reaching the floor, the downdraft airflow is diverted towards side exhaust plenums, which are outfitted with exhaust filters made of continuous glass fiber woven into an open pattern to prevent saturation and poor filtration.

Stage 3

As the air passes through the filters and within the exhaust plenum, any remaining air-laden paint is forced to change direction many times via exhaust fans to further ensure proper filtration and prevent the occurrence of fogging. Clean air is then filtered outside of the spray booth.
