により整流されクリーンルーム内部２に放出される。4 is a main filter case, which is fixed to the ceiling of the clean room with an L-shaped fitting, and its lower surface protrudes into the clean room. This main filter case 4
The inside is divided into a pressure chamber A and a main filter storage chamber B, and a cleaning air outlet 6 is provided at the bottom, and a punching plate for rectification is attached below it. A fan case 8 housing a fan 7 is fixed to the side of the main filter case 4, and an air suction port 9 is provided on the side of the fan case. The dust-containing air that is sucked in by the fan 7 from the air suction port 9 into the air purification unit to which the pre-filter 10 for removing coarse IIG is attached is filtered by the pre-filter 10 and then sent to the fan 7. fan case 8
The air is sent from the inside to the pressure chamber inside the main filter case 4, passes through the main filter 4, is sufficiently dusted and sterilized, becomes clean air, passes through the air outlet 6, is rectified by a punching plate, and is discharged into the clean room interior 2. be done.

取付けられているので、第１図、第２図に示すよう番し
一屋天井１とクリーンルーム天井３の間の天井裏が狭い
場合あるいはフィルタユニットを薄形にした場合吸込口
９も狭くなり、ここでの圧力損失が大きく処理風量が小
さくなってしまう。However, in the conventional filter unit, the air suction port 3' is installed vertically in the fan case 8 so that it faces both the ceiling 1 and the ceiling 1, as shown in Figures 1 and 2. If the ceiling space between the clean room ceilings 3 is narrow, or if the filter unit is made thin, the suction port 9 will also be narrow, resulting in a large pressure loss and a small processing air volume.
従って天井の低いＩＩ屋にこの種のフィルタユニットの
取付はむづかしく、またフィルタユニットの茸形化も困
雛であった。Therefore, it is difficult to install this type of filter unit in a second-hand shop with a low ceiling, and it is also difficult to make the filter unit mushroom-shaped.
本発明はこれらの欠点をなくし狭い天井裏でも吸込口の
開口面積を十分広く確保できるフィルタユニットを提供
するものである。以下実施例について説明する。The present invention eliminates these drawbacks and provides a filter unit that can ensure a sufficiently wide opening area of the suction port even in a narrow attic space. Examples will be described below.

高さが小さくなるように天井裏劾高さに応じて決める。As shown in FIGS. 3 to 5, the present invention has a fan 3' and a part of the corner facing both the ceiling and the ceiling of the fan 3' case 8, so that the air sucked in is covered by the clean room ceiling 3 even if the vertical height is low. Fi without pressure loss
It can be reduced by 9' by making it sufficiently large. The inclination angle of the inlet is 9' from the height of the attic.
・Determine according to the height of the ceiling so that the vertical height of the entrance door will be small.

ともできる。As is clear from the above description, according to the present invention, it is possible to provide a large air suction port and pre-filter in a narrow part of the filter unit, and the filter unit can be installed in a narrow space such as the ceiling. It is possible to increase the amount of air processed by the filter unit by suppressing the pressure loss at the air suction port as much as possible, and it is also possible to make the filter unit thinner.
