Air Knife Puts An End To Drying Mystery, Prior To Painting Yankee Gas was in the process of converting their solvent based painting system, of their propane tanks, when the problem was raised that the tanks were not dry enough prior to proceeding into painting. The drying of their tanks was essential in order to move forward with the appropriate painting system. Their drying setup consisted of compressed air blow-off, which wasn’t effective and didn’t provide enough water removal to the point where they were ready for painting. Sonic Air Systems (Brea, CA) was given the opportunity to Quote a Drying System and presented a new approach to an existing technology. They started with their standard Air Knives but made one modification which had a huge impact, force that is. Sonic suggested the use of an altered gap which would better focus to the contours of their tanks, which also decreased the overall required horsepower. Smarter, easier, and more efficient. The application involved removing DI rinse water from the outer surfaces of their barbeque size propane tanks (18”H x 11”dia) traveling on an overhead conveyor at 10 FPM, prior to their paint booth. Residual water on the tanks prevented the paint from adhering, so a dry tank was essential. They especially had issues on humid days, where the bottles seemed to stay wet, no matter how much compressed air they through at it. The Sonic “engineered” Solution: Sonic Air presented a solution using (2) air knives, slightly angled, to concentrate on the sides and top drying. A third knife was utilized to remove the Due to the handle and base ring located farther away from the knives than the body of the tanks Sonic employed their experience and used a similar design from a fender drying application for a major United States motorcycle manufacturer. The air knife gap, or slot, is adjustable along the length allowing the gap to open wider. This allowed the knife gap to be adjusted at the top and bottom, independently, to make up the distance to the handle and lower ring, but while maintaining a standard gap in the middle concentrating on the bodies. This type of forward approach not only followed the contours of their bottles but also reduced the required horsepower demand. Sonic Air also presented further price reducing solutions by offering the use of ABS tubing as opposed to Plated Steel in order to further reduce costs. Once installed the air knives simply produced results and eliminated the residual water. With air knife exit velocities reaching 340 mph at the exit, it was no wonder that the results were night and day.
