All of the air passes through the pre-filter, then through the burner or around the heat exchanger. The outside air is heated to the desired cure temperature, as defined by the booth controls.

What are the 3 types of paint booths? There are four main types of automotive paint booths to choose from including a crossdraft booth, semi downdraft, sidedraft and downdraft.
How does a downdraft paint booth work? In a downdraft booth, the air creates an envelope around the car. The air is drawn down, and over the vehicle, excess overspray is carried into the pits, through a series of filters before being exhausted to the atmosphere. Full downdraft paint booths require a pit for the airflow path.
What is a side draft paint booth? Side-draft or side-downdraft paint booths operate by introducing air through the ceiling and exhausting the air through the side-walls. The entire ceiling is filtered and the entire or vast majority of the length of the paint booth’s walls are filtered for exhaust.
What is a semi downdraft paint booth? The semi-downdraft booth is a hybrid, combining features of both crossdraft and downdraft booths. Air is introduced into semi-downdraft paint booths through the ceiling in the first 25 to 30 percent of the booth.
