Cordless extractors vacuum up silica dust, reducing respiratory hazards from airborne dust and preventing accumulation on floors, surfaces, and tools. Their universal hose connector attaches to the vacuum port on a compatible power tool, extractor attachment, or dust shroud. They draw in dust produced by cutting, drilling, grinding, or surfacing concrete, masonry, rock, and other materials containing silica. They capture fine particles in their filters and collect dust in their onboard tank. These cordless extractors operate in areas without access to wired power, eliminate the tripping hazard of a cord, and run on brand-specific batteries.
