The Sand and Dust Test Chamber SN441-2250L is engineered to meet IEC 60529 IP5X & IP6X test standards, providing reliable simulation of harsh dust‑laden environments for product qualification and reliability verification.
This equipment is widely used to evaluate the resistance of electrical and electronic products, automotive and motorcycle components, seals, and enclosures against dust ingress. It assesses product performance during real‑world use, storage, and transportation in sandy or dusty conditions, helping manufacturers identify potential damage risks caused by airborne particulate matter. The chamber accurately simulates open‑air sand and dust environments generated by natural conditions or artificial disturbances such as vehicle motion.

The system features a conical funnel structure with a bottom dust collection port. A high‑pressure turbine circulation fan draws dust from the bottom extraction port, conveys it to the top of the inner chamber, and allows it to fall freely from top to bottom. This creates a continuous, repeatable dust circulation cycle for consistent testing.
