Non-Contact Dry Cleaning System

[INQ. NO. 2608M04] Removing fine foreign particles is a critical task that determines yield in display- and battery-manufacturing processes.
As processes advance ‒ such as larger panels and the realization of high resolution ‒ the importance of particle-removal equipment has grown. In this context, Korea’s AF ONE CO., LTD. has presented a non-contact dry cleaning system developed in-house.
AF ONE participated in K-Display 2026, recently held at COEX in Samseong-dong, Seoul, and demonstrated its proprietary cleaning brand, BUSC. This system is designed for a non-contact method that eliminates physical friction with the substrate.
The company’s CEO explained, “Unlike the ultrasonic or whirling methods primarily adopted by existing overseas equipment, we have improved cleaning performance by independently developing a ‘blow-up’ method that compresses internal air and sprays it through dual nozzles.”
A specially designed head shoots gas to detach foreign particles, while a controller sucks them in to prevent particle scattering. The CEO added, “We implemented a system through fluid analysis so that foreign substances are immediately sucked in without being blown away, even when air is blown downwards.”
The system can be customized for various shapes, including flat substrates, 4D curved surfaces, roll-to-roll surfaces, and metal masks.
