The BD Diesel Positive Air Shutdown (PAS) system provides an essential safety feature for various industrial and heavy-duty applications, including mining, oil refineries, forestry, mobile welding, septic removal, and refueling operations. Designed to rapidly cut off engine air supply, it effectively halts diesel engine operation within seconds, ensuring safety during emergencies. The system features an inline butterfly valve installed in the air intake line, activated by a heavy-duty electrical solenoid that trips a safety cam, causing immediate shutdown. This design minimizes parts, reduces overall size compared to other units, and enhances reliability.
Constructed from corrosion-resistant aluminum and stainless steel components, the PAS system is built to withstand harsh environments. Weatherproof electrical connectors further ensure durability and dependable operation in outdoor or wet conditions. Installation is straightforward with no welding required, utilizing innovative bead lock boots that secure the system components firmly in place. The kit includes all necessary hardware such as wiring harness, clamps, drill template, heat shrink, solder, and bead ring, making it suitable for a wide range of vehicle configurations.
This emergency shutdown system is compatible with 24-volt systems and is ideal for vehicles requiring manual control or automatic over-speed electronics integration. The system’s effective air cutoff method makes it the most reliable solution for engine safety, preventing potential accidents or damage during critical situations. With a 24-month or 24,000-mile warranty, the BD Diesel PAS system offers a robust and dependable safety upgrade for fleet and industrial vehicles, ensuring peace of mind during demanding operations.
