The BD Diesel 1036733 Positive Air Shutdown (PAS) system provides a reliable emergency engine shutdown solution for heavy-duty diesel applications across industries such as mining, oil refining, forestry, mobile welding, septic removal, and refueling operations. This system is designed to quickly cut off the air supply to the engine, effectively halting fuel combustion and shutting down the engine within seconds. The inline butterfly valve is installed in the air intake line and is activated by a heavy-duty electrical solenoid, ensuring a prompt response during emergency situations. The PAS system includes essential components such as the air shutoff valve, wiring harness, bead lock boots, module, clamps, Velcro strips, drill template, heat shrink, and solder, making installation straightforward without welding or complex modifications. Its robust aluminum and stainless steel construction, along with weatherproof electrical connectors, ensures durability and resistance to corrosion in demanding environments. The compact design reduces overall size compared to similar units, facilitating easier integration into existing systems. The system’s safety features include a locking lever that securely holds the valve in place during operation, preventing accidental activation or deactivation. Suitable for various vehicle configurations, the BD Diesel PAS system is a critical safety device that provides rapid engine shutdown when needed, helping prevent damage or hazardous situations during critical operations.
