Product Features
High-Concentration Fine Dust Simulation
Capable of generating suspended dust with particles ≤5 μm in diameter (e.g., talcum powder), reaching concentrations up to 5 kg/m³, with continuous testing durations of up to 8 hours.
Negative Pressure Sealing Detection
Maintains a negative pressure of 0.5–2 kPa inside the chamber, with real-time monitoring of dust leakage via differential pressure sensors, achieving a sensitivity of 0.1 Pa.
Self-Cleaning System
Utilizes multi-stage filtration and pulse反吹 technology, allowing 98% of dust to be recovered and reused after testing, with residual dust rate <0.1%.
Sales Q&A
Q: Do samples need to be powered during testing to monitor internal dust ingress?
A: Supports internal dust monitoring probes, enabling real-time detection of internal dust concentration and联动 electrical performance testing.
Q: Can the device simulate dust testing under desert day-night temperature variations?
A: An optional temperature and humidity control system is available, enabling combined temperature-humidity cycling and dust testing within the range of -20°C to +80°C.
Q: Does the dust recovery system cause secondary pollution?
A: The recovery system is equipped with HEPA filtration and activated carbon adsorption, with emitted dust concentration <0.01 mg/m³, meeting environmental protection requirements.
