ESPEC dust chambers provide a low-mess solution to common settling dust test requirements for automotive components and electronics cabinets. Our deep W-shaped hopper provides better collection and dispersion dust without needing a vibration unit to shake the dust to the bottom of the collector.

These chambers have a unique clamshell lid for easier, cleaner loading, compared with traditional top-loading designs. Optional reach-in glove ports allow rotating the test sample without opening the door.

The touch screen controller allows setting the duration of the agitation, the settling time of the dust, and the overall test time.  The optional underpressure vacuum is also managed from the controller. 

Applicable Test standards :

Automotive standard for light fixtures SAE J575 and J2139 require settling dust test with Portland cement. ISO 20653 standard of Ingress Protection (IP) levels 5K and 6K require dust testing: IP 5K Dust shall only penetrate in quantities which do not impair performance and safety; IP 6K Dust shall not penetrate. The IEC 60068-2-68, method LA2 and 60529 IP tests may require underpressure of the test sample.

The dust chambers can be used with all grades of Arizona road dust, talcum powder, or Portland cement.

Other sizes and capabilities are available upon request. Please contact us with your application.
