This special sand and dust test chamber for airbags from Beier Labs Equipment Jiangsu Co., Ltd. uses compressed air to propel dust to flow over the surface of test specimens at a specified velocity, 

thereby evaluating the specimens' ability to resist the penetration of dust particles, resist abrasion or blockage caused by sand and gravel, as well as their storage and operational performance 

when exposed to dust.
