Document Type and Number:
Japanese Patent JPH0866341
Kind Code:
A
Abstract:
PURPOSE: To provide a filter without any forming inflammable dust which causes motor firing by containing spots of powdery active carbon arranged in front of a turbine and printed on an air-permeable supporting body or synthetically prepared spherical active carbon. CONSTITUTION: An order absorbing filter is arranged behind a dust absorbing filter and in front of a turbine, and contains spherical active carbon (spherical carbon) having a diameter of 0.1-2 mm which is synthetically prepared on an air-permeable supporting body or small spots of printed lump or pile having diameter and height of 0.2-1 mm consisting of bonded powdery active carbon (printed carbon). And, active carbon having an inner surface of 900 m<2> /g or more is used. Powdery active carbon of printed carbon has a particulate diameter of 0.1-50 μm, preferably 3-10 μm.
