Abort Gate systems are spring-assisted electromagnetic dampers that close within 500 milliseconds to divert sparks, flames, and smoke away from building interiors.
These devices provide essential building and personnel protection for indoor dust collection systems by isolating the return air path during a fire event. Our configurations ensure full compliance with NFPA 664 and 654 standards for industrial safety.

The Abort Gate serves as a high-speed safety barrier for facilities utilizing return air from dust collectors. When triggered by an upstream infrared spark detector, the energized electromagnet releases, allowing a spring-driven blade to snap shut and divert dangerous combustion products through a 90-degree adjustable discharge hood.
This action prevents hazardous gases and fire from entering occupied workspaces, directing them instead to a safe external location. Constructed from galvanized steel or 316SS, these gates are engineered for durability in high-velocity pneumatic environments. Because NFPA 664 requires manual reset, these gates require personnel to physically inspect the unit before returning the system to normal operation, preventing accidental re-exposure to explosive atmospheres.
