The self-cleaning FESTOOL filter bag prevents caking with its unique pliable fleece material and unlike the rigid design of many other types of bags, such as paper bags
Caking of dust reduces the effective suction power dramatically resulting in poor extraction efficiency and performance
This means that your FESTOOL dust extractor continues to deliver full suction until the bag is virtually completely full
Traps dust particles down to 5 microns, reducing wear and tear as well as the expense of frequent filter replacement
The tear resistant material and integrated closure on the bag shuts the opening to prevent spilling
