A dust barrier, when paired with the SYS-AIR Air Filter (#577790 or #577791) and Air Supply Hose, effectively traps dust and dirt within the work area. It generates a vacuum that expels dust from the room, enhancing air quality and keeping nearby spaces nearly dust-free. The air filter seamlessly integrates into the dust barrier. The flexible 19-1/2 ft (6 m) hose can be positioned directly at the dust source, minimizing dust particle spread. It's also ideal for confined spaces. Everything is easily accessible, portable, and securely stored in a Systainer, which can be connected to the air filter or extractor for convenient transport. Key features include seamless integration, effective dust collection, and cleaner work. Included: (1) SYS-AIR Air Supply Hose, (1) Adapter base, (1) Strap, (1) Systainer M 437.
