ATMARS sand and dust test chambers simulate a comprehensive environment to test the exposure of automotive and electronic components at concentrated levels of dust in order to validate products seal integrity.
Product Features
ATMARS dust testing chamber vertical circulation airflow carries dust and the test dust can be recycled;
The whole ventilation uses imported stainless steel plate, The bottom of the air duct is connected with the conical hopper, the air inlet and outlet of the fan are directly connected with the air duct, and then the top diffuser of the working chamber is connected to the working chamber body in proper position to form an "O" closed vertical blowing dust circulation system, so that air flow can flow smoothly and the maximum dust dispersed evenly;
Using a single high-power low-noise centrifugal fan, according to the test requirements to adjust wind speed by conversion speed regulator
