PROBLEM TO BE SOLVED: To provide a supply air purifying device capable of reducing the frequency of maintenance regarding the supply air purifying device which purifies air containing dust and takes in the purified air.SOLUTION: In a supply air purifying device 1 which includes dust revolving separation means 4 and a dust collecting chamber 5, an upper surface 7 of the dust revolving separation means 4 is provided with an inclination toward an outlet 8. In a case where moisture contained in air made effluent from the outlet 8 is attached to the interior of a duct, is condensed, is turned to droplet-like water particles, drops and is attached to the supply air purifying device 1 when air containing moisture in large amount is sucked, the droplet-like water particles are moved along the inclination, are caused to flow into the dust revolving separation means 4 from the outlet 8 and are finally discharged from an inlet 6 to a device external part. That is, the droplet-like water particles attached to a top surface of the dust collecting chamber 5 are caused to flow to the dust revolving separation means 4 side, are discharged from the dust revolving separation means 4 to the device external part, thereby, are separated from dust, the dust is caused to hardly adhere to the interior of the dust collecting chamber and the frequency of maintenance is reduced.SELECTED DRAWING: Figure 2 |
