Several Small Air Knives Remove Dust From Robot

We often are successful using a Super Air Knife to blow off product traveling on a conveyor or drying bottles in a labeling application. While these are common uses, sometimes we get a unique application that isn’t as clear cut a solution and requires several units and strategic placement to achieve the best result.

This was the case recently as I was working with a robotics company that was needing to contain debris inside a vessel as they removed a robot. They were needing to blow dust off all sides of the robot but had limited mounting space available to cover the round, 24″ diameter opening. Originally, they were considering using (4) 24″ Super Air Knives and mounting the units in a square pattern but were concerned that some parts of the robot wouldn’t be treated effectively and the air consumption might be too great.

I recommended they use (8) of our 9″ Super Air Knives and mount the units in an octagon type pattern around the opening. This setup would allow them to blow off the entire circumference of the opening, treating all sides of the robot from a relatively equal distance to achieve consistent results, as it is removed from the vessel. By going to several smaller knives, they would reduce the compressed air usage, making the operation more efficient. In addition, since they were only needing to blow dust off the robot, using a pressure regulator, they may be able to operate the knives at a lower pressure, further reducing the overall air consumption.
