Sand and Dust Test Chamber
This 23-second video introduces the DERUI DR-IPX56-216L sand and dust test chamber, a 600×600×600 mm working-chamber tester that reproduces dust-laden air flow to evaluate how the seals and enclosures of electrical and electronic products, automotive and motorcycle parts resist the ingress of airborne particles. Dust is drawn from a conical hopper at the bottom of the chamber, delivered to the top of the inner box and then falls freely from top to bottom, creating a continuous and repetitive cycle that simulates open sand and dust environments caused by natural conditions or by artificially disturbed air flow such as vehicle movement.

How a Sand and Dust Test Works
Step 1 - Load the specimen
Place the test specimen inside the working chamber (load capacity 10 kg). Components that must operate during the test are connected to the dust-proof C/S test piece power socket (AC 220 V 16 A).
Step 2 - Set the parameters
On the PLC touch screen, set the dust blowing time (stop/blow), the cycle period, the test time and, where required, the negative pressure difference. Dust blowing time, vibration time, cycle and vacuum time are adjustable from 1 s to 99 h.
Step 3 - Run the dust cycle
Dust is drawn from the hopper at the bottom and delivered to the top of the inner box, then falls freely from top to bottom — a continuous, repetitive cycle at a concentration of 2 kg/m³ and an airflow velocity of not more than 2 m/s, with the dust optionally heated to RT+10 °C–60 °C.
Step 4 - Inspect and verify
After the test, examine the specimen for particle ingress, then evaluate the result against the requirement of the invoked standard, dust grade and acceptance criteria.

Where Sand and Dust Testing Is Used
▸ Electrical and electronic products — seals and enclosures are checked for the ingress of air-borne particles under sand and dust conditions.
▸ Automotive and motorcycle parts — components that meet dust-laden air flow during operation, storage and transportation are verified against the required protection level.
▸ Seals and sealed assemblies — the test is designed for preventing sand and dust from entering seals and enclosures, and for verifying their performance in use, storage and transportation.
▸ Verification of particle effects — the purpose of the test is to determine the potential harmful effects of particles carried by air flow on electrical products.
Design Principle of the Dust Circulation
A conical hopper is designed with a dust collection port at the bottom. The suction inlet of a high-pressure turbine circulation fan is installed at the dust extraction port at the bottom end of the chamber. The extracted dust is delivered to the top of the inner box and then falls freely from top to bottom, which initiates a continuous and repetitive cycle.
The chamber is composed of the sand and dust test chamber, dust suction port, circulating dust blowing device, vacuum extraction system, flow valve, heating system and protective screen mesh. The chamber is fitted with an observation window and an internal lighting lamp for monitoring the test.
