Main difference between a “dust control system” and a “containment isolator” is the System behaviour during an Emergency Situation.
A “dust control system” is used to limit the pollution during some manufacturing operations, for example empting bags or filling bags with powders.
These systems do not have any specific system behaviour during emergency situations, for example during an energy or compressed air loss, or if a glove is removed, or if a window is brocken.
A “containment isolator” must have a specific system behaviour during emergency situation. During the project a Risk Analisys must be performed and a solution for any emergency that can occour must be determined.
Isolator makes the difference when things go wrong!!
