Import Dust Resistance Test Chamber — Buy in Bulk from Supplier in China

The Dust Resistance Test Chamber from Grande Electronics Technology Limited is designed to simulate dusty environments for evaluating the sealing performance of electronic, automotive, and LED products. It generates controlled airborne particulate conditions using dry talcum powder, portland cement, or smoke ash, with adjustable airflow and environmental parameters to replicate real-world contamination scenarios.

The chamber maintains a temperature range of ambient +5°C to 50°C and humidity between 45% and 75%, both adjustable via digital control. Airflow velocity is variable from 0 to 4.99 m/s, with a standard setting of 1.5 m/s. Three interchangeable metal mesh screens with line spacings of 32 mm, 75 mm, and 250 mm are included to standardize dust particle distribution. The system requires a clean compressed air source at 1 to 3 kg/cm² for dust injection control.

This equipment is primarily purchased by product development labs, quality assurance departments in electronics manufacturing, and automotive component suppliers who must comply with IP65, IP66, or similar ingress protection standards. Buyers typically order single units for in-house testing. Power requirement is 380V, 3-phase, 50/60 Hz. Packaging is heavy-duty wooden crate with internal foam bracing. Lead time is 30 to 45 days after order confirmation.

Grande Electronics Technology Limited is based in Chashan Town, Dongguan, Guangdong Province, China, a known hub for environmental test equipment manufacturing. The supplier lists a broad product range including thermal shock, humidity, and salt spray chambers, suggesting established production capacity. However, the listing provides no verified certifications, no response rate, and no export documentation references, indicating limited transparency despite a diverse catalog.

The supplier claims to be a manufacturer and offers customization, but does not state years in business, workforce size, or client names. The mention of CE certification is unverified in the source data. Buyers should treat this as a factory with capability to produce standard environmental test chambers, but must independently confirm compliance with international standards like IEC 60529 or ISO 12103 before procurement.
