<p>PROBLEM TO BE SOLVED: To provide a powder-containing air supply device which can transport a uniform and arbitrary concentration of powder-containing air to plural places with a relatively simple structure and can be flexibly adapted to an existing testing room, and a powder exposure testing room with the device built in.SOLUTION: A powder-including air supply device comprises: a powder feeder 2 which can reserve powder temporarily and feed an arbitrary amount of powder; a mixing chamber 3 which receives the arbitrary amount of powder from the powder feeder 2, introduces an arbitrary amount of air from the outside and dispersion-mixes the powder into the air to obtain an arbitrary concentration of powder-containing air; and one or more supply units 4 which supply the arbitrary concentration of powder-containing air from the mixing chamber 3 to desired places. The arbitrary amount of powder from the powder feeder 2 and the arbitrary amount of air from the outside are received and introduced into the mixing chamber 3 for dispersion mixing, and the resulting uniform and arbitrary concentration of powder-containing air in the mixing chamber 3 is supplied to the desired places by the supply units 4, to solve the aforementioned problem.</p> |
