LIB Walk-in Dust Test Chamber features a reinforced modular structure with customizable sizes for oversized products and batch testing. The interior is made of SUS304 stainless steel for strong corrosion resistance and long-term durability, while the exterior uses heavy-duty coated steel panels for enhanced strength and insulation. The equipment is equipped with a programmable PID control system for precise adjustment of dust concentration, airflow circulation, vacuum pressure, temperature, and test duration. The intelligent touchscreen controller supports multi-step automatic operation and remote communication for long-term testing. Large observation windows with integrated lighting allow clear monitoring of test specimens during operation.
Working Principle of the Walk-in Dust Test Chamber
1. Large Walk-in Structure for Full-Scale Product Testing: The walk-in dust test chamber is designed for testing large products and complete assemblies that cannot fit into standard laboratory chambers. Internal dimensions can be customized for vehicles, industrial cabinets, photovoltaic systems, military equipment, and large mechanical components. The spacious design also supports simultaneous batch testing to improve efficiency in industrial quality verification processes.
2. Stable and Uniform Dust Circulation System: The chamber uses a high-efficiency dust circulation system that continuously disperses fine test dust vertically throughout the workspace. Built-in circulation fans, dust recovery systems, and mesh filtration maintain stable dust concentration and prevent uneven particle accumulation. Heating elements prevent moisture absorption and dust caking, ensuring reliable long-term testing stability.
3. Precise Vacuum and Pressure Control: An integrated vacuum system allows the chamber to perform enclosure leakage testing according to IP5X and IP6X requirements. Adjustable vacuum pressure simulates real operating pressure differences found in outdoor and transportation environments. Flowmeters and pressure monitoring systems provide accurate data feedback throughout the entire testing cycle.
4. Durable Industrial-Grade Construction: The chamber interior uses SUS304 stainless steel with smooth surfaces resistant to abrasion, corrosion, and dust accumulation. Reinforced external steel panels improve structural durability for continuous operation under demanding industrial conditions. Heavy-duty sealing systems and electromagnetic door locks ensure chamber integrity and operator safety during high-concentration dust testing.
5. Intelligent Programmable Control System: The PID touchscreen controller supports up to 120 programmable test groups with multi-step sequencing capability. Operators can independently control dust blowing intervals, vacuum cycles, airflow speed, and temperature parameters. Remote communication and multilingual interfaces simplify operation for global manufacturing environments and automated testing laboratories.
6. Real-Time Observation and Operational Safety: Large viewing windows equipped with lighting systems and dust-cleaning mechanisms allow continuous observation of specimen conditions during testing. Multiple safety protections—including overcurrent protection, overheating protection, phase protection, leakage protection, and emergency stop systems—ensure safe and stable operation during long-duration industrial testing cycles.

Applications and Typical Dust Test Conditions
The LIB Walk-in Dust Test Chamber is used for dust protection, sealing performance, and durability testing in automotive, aerospace, electronics, energy, railway, and industrial applications. It complies with IEC 60529 (IP5X/IP6X), ISO 20653, IEC 60068-2-68, MIL-STD-810, ASTM D1739, and other standards. Typical tests include IP6X vacuum dust testing for 8+ hours using fine talcum powder or Arizona dust (<75 μm) for automotive components such as batteries, lamps, sensors, and connectors. Electronics, railway, and industrial products are also evaluated under IEC and other dust circulation conditions, sometimes combined with vibration, to ensure long-term reliability in harsh dust environments.
