1. What is the difference between the various airflow types?

There are really only two basic types of air flow, Cross Flow and Down Draft. Here is a rudimentary description of them both (there is also a diagram at the bottom of this page that may help you get a better sense of the differences.

Cross Flow

As the name suggests, the air in this type of booth flows horizontally across the booth, from the front of the booth to the back, from back to front, or from one side to the other. A Front Air Flow booth is one of the simplest examples of the Cross Flow. The air comes in through the front filtered doors of the booth. The clean air then travels horizontally through the “work area” of the booth, where the painting takes place. Finally, the continues to the rear of the booth, taking with it the over spray and airborne particulates. The rear section contains a filtered exhaust plenum, which draws the air through the exhaust filters before ducting the air out of the facility and into the outside environment. Other common cross flow models are the “Front Air Flow”, the “Reverse Air Flow”, and the “Semi Down Draft”. The name of the Semi Down Draft is a bit confusing, but make no mistake, it is indeed a cross flow.

Down Draft

Again, the name is an apt description, as the air in this type of booth comes in at the top of the booth and travels vertically down to the bottom. A Full Down Draft booth is a both where the air enters through filtered openings in the ceiling, and travels vertically through the work area. The air in this type of booth exits through an “Exhaust Pit” that has been built underneath the booth. This pit has grates over it, and serves as the exhaust plenum. The air is filtered off over spray and airborne particulates, and ducted out of the facility.
