The Kraemer MFG high speed Abort Gate is used prior to returning air from the dust collector back into the building. In the event of an explosion, the purpose of the Abort Gate is to redirect flames and pressure to the atmosphere, protecting personnel and the building.
The Abort Gate is controlled by an electrical signal generated by a spark detection system. The electrical signal releases the latching device, allowing the gate to open to the atmosphere. The gate is reset by a manual handle as per NFPA Code 664 (8-4).
