Overview

The military standard sand and dust test chamber uses a high-power fan to push a certain concentration of sand and dust at a certain flow rate through the surface of the test samples, in order to evaluate the ability of these test samples (equipment) to resist the penetration effect of dust particles, the ability to resist the abrasion or blockage effect of gravel, and the ability to store and operate when exposed to dry sand or dusty atmosphere
