Typical Applications
The dust chamber is widely used in industries where products must operate reliably in dusty or off-road environments:
- Automotive electronic control units (ECU).
- Sensors, connectors, and wiring harnesses.
- Battery packs and BMS enclosures.
- Lighting systems and signal devices.
- Power distribution boxes.
- Industrial electrical enclosures.

Key Features
- Corrosion-Resistant Stainless Steel Construction
Inner and outer chambers are made of high-quality stainless steel, offering excellent durability and resistance to corrosion under prolonged dust exposure. - Customizable Chamber Sizes
Available in bench-top, floor-standing, double-door, and walk-in configurations, suitable for small components up to full vehicles. - Sealed Dust-Tight Structure
High-performance rubber gaskets ensure complete sealing during IP5X and IP6X testing. - Optimized Dust Circulation System
A powerful circulation blower combined with vertical airflow keeps dust evenly suspended throughout the test. - Anti-Clogging Funnel with Vibration System
The conical bottom design collects falling dust, while an integrated vibrator prevents powder agglomeration and ensures smooth recirculation. - Integrated Heating System
Mica heating elements reduce moisture effects and prevent dust clumping, ensuring repeatable test conditions. - Vacuum System for IP5KX / IP6KX Testing
Includes vacuum pump, valves, flow meter, dust filter, and pressure gauge to simulate internal pressure reduction in test samples. - PLC Touchscreen Control
A 7-inch touch screen allows precise control of dust circulation cycles, vibration intervals, vacuum parameters, and test duration. - Real-Time Observation
Tempered glass viewing window with manual wiper and internal lighting enables continuous visual inspection during testing. - Comprehensive Safety Protection
Equipped with overload protection, leakage protection, and short-circuit breakers for safe operation.

How IP5KX / IP6KX Dust Ingress Testing Works？
IP5KX/IP6KX testing per ISO 20653 evaluates dust ingress by applying internal negative pressure to the specimen within a uniformly dust-filled chamber, drawing dust toward potential leakage paths.
IP5KX / IP6KX Dust Chamber Test Process
- Place the test specimen inside the dust chamber and seal the door.
- Load the specified test dust and quantity.
- Configure test duration, dust circulation cycles, vibration intervals, and vacuum parameters via the PLC.
- Start the dust circulation system to maintain uniform dust suspension.
- Apply internal vacuum if required by the test standard.
- Maintain exposure for the specified duration.
- Test ends automatically with an audible alarm.
- Inspect the specimen for dust ingress according to acceptance criteria.

FAQ – IP5KX / IP6KX Automotive Dust Chamber
What is the difference between IP5KX/IP6KX and IP5X/IP6X?
IP5KX and IP6KX are defined in ISO 20653 for road vehicles and require negative pressure dust testing, whereas IP5X and IP6X under IEC 60529 are general-purpose ratings and do not mandate this condition.
What type of dust is used?
Automotive dust such as Arizona-type dust is commonly used to simulate real road dust conditions, offering a more realistic challenge than fine laboratory powders.
Can this chamber be used for non-automotive products?
Yes. Any product requiring dust ingress verification under ISO 20653 conditions can be tested, even outside the automotive industry.
