BD Diesel Positive Air Shutdown - Generic 3.5in

Engineered for ultimate safety and reliability, the BD Diesel Positive Air Shutdown (PAS) system is the industry-leading solution for emergency engine shutdown in demanding environments. This system is essential for industries such as mining, oil refinery, forestry, mobile welding, septic removal, and refueling, where rapid engine shutdown can prevent catastrophic failure and protect both personnel and equipment.

The PAS features an inline butterfly valve installed in the air intake system. When activated by a heavy-duty electrical solenoid, the valve instantly cuts off the air supply to the diesel engine, causing immediate shutdown within seconds. This is the most effective method to halt engine runaway and ensure safety.
