The installation distance between the G4 filtration module and the F5 filtration module is 200 mm, and the installation distance between the F5 filtration module and the F8 filtration module is 600 mm. Since the installation structure of the G4 / F5 / F8 three-stage filters is a general technology in the prior art, no detailed description will be given here.

[0031] A fan 21 is arranged inside the power chamber 2, and the side wall of the power chamber 2 is a sound-absorbing board 22. When the fan operates, strong airflows will be generated, and good noise reduction can be achieved through the sound-absorbing board 22. In this embodiment, as Figure 3 、 4 shown, the sound-absorbing board 22 is arranged in a multi-layer structure, which includes an outer wall board 225 and an inner micro-hole board 221. A number of sound-absorbing holes 222 are provided on the inner micro-hole board 221, and sound-absorbing materials are arranged between the outer wall board 225 and the inner micro-hole board 221 for supporting between the outer wall board 225 and the inner micro-hole board 221.
