(2) Sand dust proof test box has a dust vertical circulation air flow, test dust can be recycled using the whole wind channel using imported stainless steel plate made, wind channel bottom and cone shaped hopper interface connected, fan in and out air port directly connected to the wind channel, then in a suitable location to put the studio top diffusion port into the studio body, forming the "O" type closed vertical dust lifting cycle system, so that the air flow can flow smoothly, the largest extent to make the dust disperse uniformly, using a single high power low noise centrifugal fan, according to the test needs with frequency converter to adjust wind speed.
