The KP-SCJB1000 Blowing Sand and Dust Test Chamber is a horizontal-type environmental testing instrument designed to evaluate material resistance to sand and dust ingress according to MIL-STD-810G standards.

This chamber evaluates material ability to resist 150μm to 850μm diameter sand and dust particles that may obstruct openings, penetrate into cracks, crevices, bearings, and joints, while assessing filter effectiveness.

The chamber features a funnel structure with bottom dust collection and turbine circulation. Dust is pumped into the chamber bottom, circulated upward, and blown horizontally across test specimens in a controlled environment.
