Technical Description: An abort gate redirects airflow in a dust collection system when a connected detector signals a problem. During normal operation, air follows the main duct path. When activated, a movable gate changes that path and directs the air toward a designated outdoor discharge. A common application is the return air duct between an outdoor dust collector and a building, where diversion helps keep smoke or contaminated air from returning indoors. Other arrangements divert sparks or burning material before they reach collection equipment. The gate works with detection and control equipment as part of the overall system. Its role is airflow diversion rather than explosion isolation.
