Festool 456737 CT 22 Long Life Filter Bag is specially designed for use with CT Dust Extractors when working with routers, planers, or any task that produces large wood shavings or chips in volume. Unlike standard filter bags that fill up quickly during these heavy-duty applications, this Longlife filter bag features a non-stick, micropore plastic lining that allows it to be reused up to 500 times, making it a cost-effective and environmentally friendly choice. It efficiently captures and contains large wood chips and debris, helping you maintain a cleaner workspace and work more efficiently. The integrated cap creates a tight seal during bag removal and disposal, preventing dust from escaping and keeping your floor clean. This filter bag also traps larger particles before they reach the main filter, extending the lifespan of both the main filter and the dust extractor. Please note, it is not for fine dust created by sanding. Model Number: 456737
