Simple and safe disposal of dust from dust classes L and M. Optimally designed for use with CT MINI and CT MIDI from the year 2019 onwards. High-quality fleece filter bag that automatically cleans dust deposits inside the filter bag. When the vacuum unit is turned on, the Selfclean filter bag inflates. When the vacuum unit is turned off, the bag collapses, releasing dust deposits inside the Selfclean filter bag. This ensures longer cleanliness and a sustained high suction power. For efficient, clean, and health-conscious work with a system.
