The BD Diesel 1036732-M Positive Air Shutdown system provides a reliable emergency engine shutoff solution for heavy-duty applications across industries such as mining, oil refineries, forestry, mobile welding, septic removal, and refueling. This system utilizes a 3.5-inch inline butterfly valve installed in the air intake line, which, when activated by the heavy-duty electrical solenoid, rapidly cuts off the air supply to the engine, causing an immediate shutdown within seconds. Designed for manual operation, this system is essential for safety procedures requiring quick engine cutoff to prevent accidents or damage.
The BD Diesel Positive Air Shutdown features durable aluminum and stainless steel components, along with weatherproof electrical connectors, to ensure resistance to corrosion and harsh environmental conditions. Its compact design reduces overall size compared to other units, making installation straightforward without welding, thanks to innovative bead lock boot retention. The included wiring harness, clamps, drill template, heat shrink tubing, solder, and other installation hardware facilitate a simple, no-weld setup that seamlessly integrates into existing air intake systems.
Built for heavy-duty use, the system’s electric solenoid triggers a safety cam that rapidly closes the butterfly valve, effectively shutting down the engine in emergency situations. It also includes CAC pipes for certain vehicle models, enhancing compatibility and installation flexibility. The system is suitable for 24-volt electrical systems, requiring the specific kit 1036740 for such applications. With a 24-month or 24,000-mile warranty, this manual-controlled shutdown system ensures dependable performance in critical safety scenarios, providing peace of mind for fleet operators and industrial vehicle operators alike.
