The BD Diesel Positive Air Shutdown (PAS) system is an essential safety feature designed for heavy-duty applications requiring quick engine shutdown capabilities. Engineered for vehicles in industries such as mining, oil refining, forestry, mobile welding, septic removal, and refueling, this system effectively cuts the air supply to the diesel engine, ensuring rapid cessation of fuel ignition. The PAS system includes an inline butterfly valve installed in the air intake line, activated by a robust electrical solenoid that trips the safety cam, causing the engine to shut down within seconds. This design minimizes component count and overall size, making it a practical retrofit for various vehicles.
Constructed from durable aluminum and stainless steel, combined with weatherproof electrical connectors, the BD PAS system is built to withstand harsh environments and prevent corrosion. Its comprehensive package includes the air shutoff valve, wiring harness, PAS pipe, clamps, Velcro strips, heat-shrink tubing, a module, boots, and solder connections, facilitating straightforward installation without welding. The system also features automatic over-speed electronics and CAC pipes for compatible vehicles, providing an added layer of safety and operational control. With a two-year or 24,000-mile warranty, the PAS system offers reliable performance for demanding fleet and industrial applications.
Designed to enhance safety and operational efficiency, the BD Diesel Positive Air Shutdown system is an effective solution for emergency engine shutdowns in various heavy-duty diesel engines. Its compact design, corrosion-resistant components, and easy installation make it suitable for a wide range of vehicle configurations, particularly where rapid response to engine over-speed or emergency shutdown is critical. This system is an ideal upgrade for fleet managers and operators seeking a proven, durable safety mechanism that ensures engine shutdowns are quick, reliable, and safe under extreme conditions.
