The BD Diesel Positive Air Shutdown (PAS) system, part number 1036730, provides a reliable emergency engine shutdown solution for various industrial and fleet applications. Designed to cut off the air supply to the engine quickly and effectively, this system is essential in industries such as mining, oil refineries, forestry, mobile welding, septic removal, and refueling operations where rapid engine shutdown is critical for safety and operational control. The PAS system features an inline butterfly valve installed in the air intake line, which, when activated by the heavy-duty electrical solenoid, causes the engine to shut down within seconds. This method of shutdown is considered the most effective, ensuring the engine ceases operation by preventing fuel ignition.
Constructed with durable aluminum and stainless steel components, the system is built to withstand harsh environments and resist corrosion. Weatherproof electrical connectors further enhance durability for outdoor or demanding applications. Installation is straightforward, requiring no welding thanks to the innovative bead lock design, which secures the boots in place and simplifies setup. The system includes overspeed electronics and CAC pipes for compatibility with certain vehicle models, making it a versatile solution for various diesel engines. The comprehensive package contains the air shutoff valve, wiring harness, boot, control module, clamps, Velcro strips, bead ring, drill template, heat shrink, and solder, ensuring a complete and ready-to-install package.
Safety and operational reliability are core features of this PAS system. The heavy-duty electrical solenoid trips a locked safety cam, rapidly shutting down the engine to prevent damage or unsafe conditions. The system’s compact size reduces space requirements compared to competing units, making it suitable for a wide range of vehicle configurations. The inclusion of weatherproof electrical connectors and corrosion-resistant materials ensures long-term performance in demanding environments. With a 24-month or 24,000-mile warranty, the BD Diesel PAS system emphasizes quality and dependability for critical emergency shutdown scenarios.
