As shown in FIG. 1, a blower 2 and a filter 3 are provided in the duct 1. The blower 2 is installed on the air intake 4 side provided on the upper surface of the duct 1, that is, on the ceiling side surface. The fan casing 5 of the blower 2 has an air intake opening 5a on the side facing the air intake 4, and an air discharge port 5b in the radial direction of rotation of the fan liner 6. The filter 3 is provided so as to face the air outlet 7 provided on the lower surface of the duct 1, that is, the surface on the clean room side, and is provided so as to be located on the air outlet 5b side of the fan casing 5. ing. At this time, the filter 3 comes into close contact with the filter mounting seat 8 provided approximately in the middle of the duct 1 in the height direction by tightening the tightening bolt 9 from the air outlet 7 side so that the filter 3 can be easily replaced. It is fixed. Further, a mounting portion 10 for mounting on a wall surface is provided at an end portion of the duct 1, and it is possible to mount the mounting portion 10 on a wall surface of the clean room by means of bolts or the like although not shown. As shown in the figure, in the case of having a plurality of sets of blowers 2 and filters 3, a partition 11 is provided in the duct 1 to divide them.

FIG. 3 shows an air cleaner according to another embodiment of the present invention. The same functional components as those of the embodiment shown in FIGS. 1 and 2 are designated by the same reference numerals and the description thereof will be omitted. In this embodiment, an air introducing duct 12 for connecting the air intakes 4 of the duct 1 is further provided. The air introducing duct 12 is provided on the ceiling-side surface of the duct 1, and has an air introducing port 13 at the end. The air introduction port 13 is connected to an exhaust port provided on the wall surface of a clean room or the like.
