Milwaukee 8 gal. 1-39/64 Dust Extractor, 12 Amps, HEPA Filter Type

Power-on-demand vacuums connect to a power tool for dust extraction and shut off automatically when the tool shuts off. They have an outlet on their operating panel for plugging in power tools, so that the vacuum will run only when the power tool runs. They're used for collecting dust from cutting, sanding, drilling, and grinding tools. These vacuums also function as wet/dry vacuums for cleaning dust and dirt or liquid spills.

Specialty shop vacuums are used in specific applications, such as collecting dust from power tools or removing powders and chips from workers' clothing. They include machines such as dust extractors for preventing dust buildup around machinery and wall-mount vacuums that won't take up floor space. Other specialty vacuums are designed to handle specific materials, such as ash or slurry.
