CASE STUDY: Dust Removal from Car Bodies
The Problem: Car bodies are primer coated, then sanded before entering the paint booth. Priming dust, attracted to the car body by a static charge, creates imperfections that are captured and magnified in the painting process.
The Solution: An "archway" of Model 111024 24" (610mm) Super Ion Air Knives was installed upstream of the paint booth. As the car bodies pass through, a high velocity sheet of ionized air neutralizes the static charge to release the dust and blow it toward a collection system.
Comment: Non-turbulent airflow was the reason this cleaning system worked so well. The compact, Super Ion Air Knife has the ability to move the bulk of the static eliminating ions to the car surface. It can be adjusted from a gentle breeze of air to a pounding blast with instant "on/off" capability. Uniform airflow across the entire length assures that all car body surfaces are neutralized and dust free. Best of all, the Super Ion Air Knife is easy on the compressed air system and workers' ears. They use much less compressed air than standard blowoffs and are around 69 dBA in most applications.
