Abort Gate

An Abort Gate is a high-speed damper that contains a spring assisted blade that is usually held in place by an electromagnet. It is used to divert sparks, flames, burning material, smoke, and combustion gases out of the pneumatic system to a safe location. Abort Gates are usually activated by spark detectors mounted on the ductwork upstream of the unit. Upon detection of IR by the spark detector, the system diverts the air flow through the discharge hood of the gate. The reaction time will vary somewhat depending upon the diameter of the duct however most units will react within 1/2 second (500 milliseconds).
