Positive pressure fog management system. With vapor blasting, small water molecules suspended inside the cabinet can impair your ability to see what you are doing. There are several ways to address this issue, but they are either negative pressure or positive pressure configurations. Most moisture abatement systems I've seen use vacuum to remove the moisture by attaching a Shop-vac type vacuum cleaner to the exhaust port on the cabinet. I decided to try using an HVAC fan designed to be inside the duct itself to create a positive pressure configuration. I adapted a 4" fan to 3" PVC pipe and placed the inlet adjacent to my field of view so the moving air would clear the fog improving my ability to see the work surface. So far it seems to work very well.
