Festool SC FIS-CT 48/5 SELFCLEAN Filter Bags
Festool SC FIS-CT 48/5 SELFCLEAN Filter Bags – 497539
Keep your Festool CT 48 extracting efficiently as the filter bag fills. The Festool SC FIS-CT 48/5 SELFCLEAN Filter Bags are genuine replacement dust collection bags designed for Festool CT 48 dust extractors. Their flexible fleece construction helps prevent dust from caking inside the bag, supporting consistent suction performance and efficient use of the available collection capacity.
Designed for professional workshops and jobsites, these disposable filter bags collect dust and debris while helping maintain airflow. The SELFCLEAN bag expands when the extractor starts and collapses when it stops, helping release dust deposits from the inside of the bag.
Key Features & Benefits

- Consistent suction: Helps reduce dust caking that can restrict airflow as the bag fills.
- Efficient bag capacity: Designed to make better use of the available collection volume before replacement.
- High-quality fleece: Flexible, tear-resistant construction supports reliable dust collection.

How SELFCLEAN Technology Works
Festool's SELFCLEAN system uses a flexible filter bag to help prevent dust from caking on the interior surface.
- Extractor starts: Airflow causes the flexible filter bag to expand.
- Dust is collected: Dust and debris accumulate inside the bag.
- Extractor stops: The bag relaxes and collapses.
- Dust deposits loosen: The changing bag shape helps release accumulated dust from the inner lining.
- Airflow is supported: Reduced dust caking helps maintain suction during subsequent operation.
Installation & Disposal
- Disconnect the extractor: Switch off and unplug the CT 48.
- Open the extractor: Release the locking clips and remove the top section according to the operating manual.
- Remove the used bag: Carefully remove the existing filter bag and dispose of it according to applicable requirements.
- Install the replacement: Fit the new SC FIS-CT 48 filter bag onto the container inlet until properly engaged.
- Reassemble: Replace the extractor top and secure the locking clips.
- Check the seal: Ensure the filter bag is not pinched between the extractor sections.
