Easy loading clam-shell design

The ESPEC EDC dust chambers provide a ready-made solution to common dust test standards for automotive and electronic-cabinet requirements. Often specified for use with “Arizona fine dust”, these units can also be used with talcum or concrete powder. The chamber has a “clamshell” type door/lid for easy front-loading, compared with top-loading chambers. Optional reach-in glove ports allow rotating the test sample without opening the door.

Test standards met:

  • SAE J575 (Rev. NOV2006), Section 4.5
  • ISO 20653 (2006-08-15), Section 8.3.1
