The BD Diesel 1036732 Positive Air Shutdown (PAS) system provides a reliable emergency engine shutdown solution for heavy-duty applications across industries such as mining, oil refineries, forestry, mobile welding, septic removal, and refueling operations. Designed to ensure rapid engine shutdown by cutting off the air supply, this inline butterfly valve is installed directly into the air intake line and activated by a heavy-duty electrical solenoid, causing the engine to cease operation within seconds. Its robust construction features aluminum and stainless steel components, along with weatherproof electrical connectors, to resist corrosion and withstand harsh environments. The system includes overspeed electronics, CAC pipes for compatible vehicles, and all necessary mounting hardware such as wiring harnesses, clamps, bead locks, a drill template, heat shrink tubing, solder, and boot locks, facilitating straightforward installation without welding. The compact design reduces overall size compared to competing units, making it suitable for tight engine bays while maintaining high reliability in critical situations. The heavy-duty electrical solenoid engages a locked safety cam that physically trips the air shutoff valve, ensuring an effective and fail-safe engine shutdown method. The unique bead lock design secures the boot in place, preventing accidental dislodging and eliminating the need for welding or permanent modifications. This system is essential for operations requiring a quick and dependable shutdown mechanism to prevent engine damage, environmental hazards, or safety incidents. Backed by a 24-month or 24,000-mile warranty, the BD Diesel Positive Air Shutdown is engineered to meet the demanding needs of industrial vehicle fleets and diesel engine applications, providing peace of mind in emergency scenarios.
