2m³ Dust Test Chamber IP5X & IP6X For Dry Sand Or Circulating Dust Environments Test
Product Overview:
The 2m³ Dust Test Chamber is designed in accordance with IEC 60529:2013, GB/T 4208-2017 (IP Code), and GB/T 2423.37-2006 (Test L: Dust Test). It is used to evaluate the dustproof protection (IP5X/IP6X), reliability, and operational performance of household appliances, luminaires, electrical and electronic products, and electromechanical devices when exposed to dry sand or circulating dust environments.
This chamber provides a controlled dust-laden atmosphere to determine whether the product can operate safely, resist dust ingress, and maintain storage and functional stability.
Key Features:
Pneumatic vibration system, infinitely adjustable amplitude
Variable-speed fan with frequency converter for dust circulation
Independent adjustable vacuum pressure & flow rate
Digital temperature & humidity display, visible on touchscreen
Easy dust replacement via bottom funnel with ball valve
Air filtration assembly for pressure equalization
Supports sample preheating function (e.g., luminaires can be powered on to reach stable condition before dust testing)
Full-width unobstructed door opening (2000 × 1000 mm) for easy loading of large samples
