Description
This equipment complies with the test requirements specified in GB2423.37-2006 (Environmental Testing for Electric and Electronic Products – Part 2: Test Methods – Test L: Sand and Dust Test, Test Lb).
Product Features:
1. The equipment adopts a walk-in modular structure. Inside the chamber, each of the four corners has a funnel, and the middle section uses a rotating dust brush mechanism, which sweeps dust into the side funnels.
2. The air inlet of the working chamber is equipped with a rotating sand feeding device to meet dust-blowing requirements.
3. The air circulation duct is equipped with a heating and dehumidification system.
4. The door is a double-opening type with observation windows, sealed with double-layer aging-resistant silicone rubber gaskets.
5. The outer shell and air duct are made of high-strength, double-sided galvanized steel plates with a powder-coated finish; the inner chamber is made of SUS304 stainless steel; and the frame is constructed from 10# square steel tubing, treated for rust protection and spray-coated.
6. Temperature and humidity control are managed by an intelligent controller (with direct-reading humidity sensor and touchscreen interface).
Product Purpose:
This equipment is used to test electrical and electronic products, automotive and motorcycle components, and sealing parts for their ability to prevent dust ingress under dusty environmental conditions. It evaluates the product’s performance during use, storage, and transport in dusty atmospheres. The test determines the potential harmful effects of airborne dust particles on electrical products and simulates dust-laden air environments caused by natural conditions or vehicle-induced disturbances.
