Super Air Knives Remove Water from Knee Replacement Parts

EXAIR’s Super Air Knives are the go to when you need to dry your parts as they’re traveling along a conveyor. The high velocity, laminar airflow from the Super Air Knife does a fantastic job of stripping away moisture, leaving your part dry for the next stage of the process. With models available in both 303 & 316 Stainless Steel, Aluminum, and polyvinylidene fluoride and at lengths ranging from 3″-108″, there’s a knife for every application.

I was recently working with a customer that manufactures knee replacement devices. He was designing a new blowoff station to eliminate having to have operators manually dry the parts after a washing operation. He created a test rig to test out his theory of using Super Air Knives. While conducting his tests, he was having issues completely removing the water from the parts. Due to some of the grooves and pockets, the underside was not drying in one pass. This led to him having to manually blow the parts off after they exited the basket. This would not be acceptable as the purpose was to remove the operator from this part of the process. After taking a look at some photos of the setup, I noticed that he had the knives angled so that the airflow was blowing perpendicular to the parts. In doing this, the amount of time that the part is exposed to the airflow is greatly reduced. In any blowoff application, maximizing the time & contact that the part has with the airflow is critical in maximizing effectiveness. By angling the knives so that the parts were exposed to the airstream just as they exited washing, he was effectively able to dry the parts in one pass.
