What type of spray booth is best, a reverse airflow or a front airflow?

Reverse Airflow

We recommend a reverse flow as a better design than a standard crossflow. The reason I state that is as follows. With a reverse flow design, the product entry/exit doors are located at the exhaust end of the booth. If there is any unfiltered plant air that enters the booth through the product doors due to leaks, bad seals etc., it is drawn directly to the exhaust filters instead of being drawn down the entire length of the booth like what happens with a standard cross flow booth.
