A pre-bay and spray booth combination is a setup typically used in automotive refinishing and painting facilities. It consists of two main areas: the pre-bay and the spray booth.

The combination of the pre-bay and spray booth allows for an efficient workflow, as the vehicles can be prepared in one area and then smoothly transitioned to the controlled environment of the spray booth for painting. This setup ensures that the painting process is conducted under optimal conditions, resulting in high-quality finishes.

It's important to note that the specific design and layout of a pre-bay and spray booth setup can vary depending on the facility's requirements, available space, and budget.
