I took a call from a customer today who was having a problem with residual fluid “pooling” on top of their parts after a heat treat dip tank application. After the parts are treated and removed they have to be set aside for an operator to walk around the tray with an air gun and manually blow off the parts, resulting in the fluid ending up on the shop floor. They were looking for a solution to effectively blow off the residual fluid prior to the trays being removed, so they could recover the excess fluid back in to the process and their operator could tend to other areas of production.
I recommended using 2 of our 30” Super Air Knives. The Super Air Knife produces a high velocity laminar sheet of airflow with a 40:1 amplification ratio (the ratio of entrained ambient air to compressed air) and only consumes 2.9 SCFM (per inch) @ 80 PSIG. Engineered for safety, they cannot be dead ended – meeting OSHA standard 1910.242(b) and they also meet the OSHA allowable noise exposure operating at a low 69 dBA (@ 80 PSIG).
By mounting 1 of the units on the front and the other unit on the back of the tank, they would be able to pass the tray through the high velocity airflow providing the desired blow off and recovery of the fluid. More importantly, the customer was able to eliminate the unsafe, wet floor, work environment.
