Minimizes Dust Exposure, Extends Filter Life

Installed on a dust collection system, Imperial Systems airlocks allow the collector to operate continuously since it is unnecessary to shut down the system when emptying the collection containers.

  • Limits employee exposure to dust
  • Decreases material back-up
  • Reduces filter damage
