What is an auto-cascade system?

An auto-cascade system functions as a stationary air fill system designed to automatically fill a cylinder to a specified pressure. This technology is especially significant for fire departments and emergency services, where high-pressure cylinders, like those used for breathing apparatus, must be refilled efficiently and reliably.

Auto-cascade systems utilize multiple banks of high-pressure cylinders to ensure a continuous supply of air at a predetermined pressure, typically up to 4,500 psi. When a cylinder is connected to this system, it draws from these banks in a sequential manner, optimizing the pressure as it fills. This process saves time and prevents the need for manual adjustment or monitoring, enhancing operational efficiency during critical situations.

The other options do not accurately describe an auto-cascade system. For instance, while an emergency medical supply system focuses on providing medical equipment, it does not pertain to the filling of air cylinders. A portable air pump serves a different function, primarily aimed at supplying air during rescues rather than managing the refilling process of high-pressure systems. Lastly, transporting oxygen cylinders involves logistics that do not encompass the filling or pressure management aspects of an auto-cascade system.
