Design and Fabrication of Contactless Conveyor using Air Pressure

This study presents the design, fabrication, and testing of a contactless air conveyor system that employs pressurized air to achieve non-contact transportation of lightweight objects. The prototype features a perforated fiberglass sheet and a centrifugal blower, generating a thin air film to levitate and move flat objects weighing up to 100 grams. Experimental results demonstrate stable levitation at a 0.5 mm air gap, low energy consumption (55W), and suitability for hygienic applications in pharmaceuticals, food processing, and electronics. Advantages include reduced contamination, minimal maintenance, and enhanced product longevity. Limitations, such as load capacity constraints and environmental sensitivity, highlight areas for improvement. This work underscores the potential of air-based conveyors as a clean, efficient alternative to traditional systems, with recommendations for scalability and advanced control integration.
