Super Ion Air Knife Removes Beads from Tray

Before coating an aluminum tray, our medical analysis customer needed to remove small dry powder beads from the surface of the tray to prevent defects. The production area of the trays is extremely dry at 2-5% relative humidity. This dry environment also produces a good deal of static to contend with and it was attracting these powder beads to the surface of the ungrounded aluminum tray. The customer added a tray washing station using only a Model 112118 18" (457mm) Super Ion Air Knife and Power Supply to remove the static charge and gently blow off the powder which was captured by a vacuum flow of air from a down draft table. The blow off station easily removed the debris and reduced any defective trays.
