BD Diesel Positive Air Shutdown - Generic 3.5in

BD Diesel is a well-known name for performance parts, and they offer this Positive Air Shutdown (PAS) system for situations where an emergency engine cutoff is critical. Industries like mining, oil refining, forestry, and specialized transport often require vehicles to have such safety features. The most reliable way to stop a diesel engine in an emergency is by cutting off its air supply, preventing fuel ignition. This BD Diesel PAS system uses an inline butterfly valve in the air intake line. When activated by its heavy-duty electrical solenoid, it shuts down the engine in seconds.

This system is designed to be effective and durable. It incorporates aluminum and stainless steel components along with weatherproof electrical connectors to resist corrosion, ensuring it works when you need it. The butterfly valve design is more compact than many competing units, simplifying the system and reducing the number of parts. Installation is made easier with innovative bead boot locks, eliminating the need for welding to secure hose retaining beads. For some vehicles, standard applications include automatic over-speed electronics and CAC pipes.

Think of this system like a fire extinguisher for your engine. While rare, a diesel engine runaway can occur if the engine ingests external hydrocarbons, leading to over-speeding and potential catastrophic failure. This can put lives, limbs, and your vehicle at risk. The BD Diesel Positive Air Shut-Off system acts as a safeguard, cutting the intake air supply to the cylinders and safely shutting down the engine, protecting you and your equipment.
