Aspirator blowers are compact, dual-purpose tools typically used for both blowing air and vacuuming dust, commonly featuring 400W–800W motors, 220-240V power, and air volumes ranging from 3.0 to 4.5 m3/min. These handheld devices usually include a dust bag for vacuuming, a nozzle, and a variable speed function, with no-load speeds up to 16,000 RPM
