MIL-STD-810G high concentration Laminar Airflow Sand And Dust Test Chamber

Description

This equipment is suitable for testing electrical and electronic products, automotive and motorcycle parts, and seals in dusty environments to prevent sand and dust from entering the seals and housings. It verifies the performance of electrical and electronic products, automotive and motorcycle parts, and seals in dusty environments during use, storage, and transportation. The purpose of the test is to determine the potential harmful effects of airflow-carried particles on electrical products. The test can be used to simulate open dusty air environments induced by natural environmental factors or human disturbances such as vehicle movement.

Design Principle: A conical funnel with a dust collection port at the bottom is designed. A high-pressure turbine circulating fan is installed at the dust extraction port (on the right side) to draw up the dust and send it to the bottom of the inner chamber, through the bottom to the left side of the chamber, and then into the pretreatment chamber. Dust is blown into the test chamber from the left, and the dust is blown horizontally to the right, thus starting a continuous cycle.
