BD Diesel Positive Air Shutdown (Manual Controlled) - Generic 4.0in

For industries like mining, oil refineries, forestry, and mobile welding, having a reliable emergency engine shutdown system isn't just recommended—it's often required. The most effective way to stop a diesel engine quickly in an emergency is by cutting off its air supply, preventing fuel ignition. BD Diesel's Positive Air Shutdown (PAS) system does just that. It installs an inline butterfly valve in the air intake line that, when activated by a heavy-duty electrical solenoid, shuts down the engine within seconds.

This PAS system is designed for simplicity and durability. The butterfly valve design reduces the number of parts and overall size compared to other units. It uses aluminum and stainless steel components along with weatherproof electrical connectors to resist corrosion, ensuring it holds up in tough conditions. Installation is straightforward, with innovative bead boot locks eliminating the need for welding to secure hose connections. This kit is a well-built safeguard, similar to having a fire extinguisher ready, providing peace of mind for rare but potentially catastrophic engine runaway situations caused by external hydrocarbons.

This manual control version allows for direct activation when needed. For 24-volt systems, an additional kit (part number 1036740) is required. CAC pipes are included for some vehicle applications, simplifying integration. This system is backed by a 24-month or 24,000-mile warranty.
