The "Rafuru Cleaner" is a vacuum cleaner equipped with a two-stage dust collection system that utilizes a cyclone system for handling chalk dust, in addition to its powerful suction. It is designed to be mounted on a blackboard, allowing for immediate cleaning of any chalk dust that accumulates on the rafuru. This enables you to keep the rafuru clean at all times without interrupting the lesson. 【Features】 - Chalk dust is first collected in the powder collection case after being centrifuged by the cyclone. - Fine chalk particles are adsorbed by the filter case. - The two-stage system of the powder collection case and filter case purifies the air. - The powder collection case is transparent and has a disposal level line, making it easy to check when to empty it. - It allows for convenient disposal without getting your hands dirty. - Maintenance of the filter has been reduced to about a quarter of the traditional time. *For more details, please download the PDF or feel free to contact us.
