Festool 497539 CT 48 Self Cleaning Filter Bags, 5-Pack a solution to common dust extraction problems with its innovative self-cleaning filter bag design. Unlike traditional rigid bags that suffer from dust caking and loss of suction, these pliable fleece bags prevent caking, ensuring your dust extractor maintains full suction power until the bag is nearly full. This unique feature not only enhances extraction efficiency but also reduces strain on your dust extractor's motor, helping to extend its lifespan. The filter bags act as a pre-filter, capturing particles as small as five microns—about the size of a red blood cell—protecting your main HEPA filter and reducing the need for frequent s. Disposal is simple and mess- thanks to an integrated closure that seals the bag, while the tear-resistant material prevents blowouts. This pack includes five bags, designed to keep your work environment cleaner and your equipment running smoothly. Model Number: 497539
