Product Description

Like a fire extinguisher or an earthquake kit, being prepared for a Diesel Engine Runaway is crucial. Diesel Engine Runaway, though rare, occurs when external hydrocarbons enter the engine, leading to overspeeding and potential catastrophic failure, endangering life, limb, and vehicle. BD Diesel's Positive Air Shut-Off (PAS) offers a reliable solution by cutting off the intake air supply to the cylinders, safely shutting down the engine. The innovative butterfly valve design reduces part count and overall size compared to competitors, using durable aluminum and stainless components with weatherproof connectors to prevent corrosion. Installation is easy with bead boot locks, eliminating the need for welding. BD Diesel's PAS is available with standard over-speed electronics or manual control, and some vehicles include CAC pipes. Stay safe and prepared with BD Diesel’s advanced protection technology.
