Industrial collectors and pre-separators capture debris and silica dust generated by concrete floor resurfacing, sandblasting, and other big jobs that produce too much dust for a typical dust extractor to manage. They suction dust into their hose and through their filters, reducing respiratory hazards from airborne dust and preventing accumulation on floors, surfaces, and tools. These machines are commonly used to collect dust produced by cutting, drilling, grinding, or surfacing concrete, masonry, rock, and other materials containing silica.
