A breathing air cart is an essential part of any worker's package if they are going to be working in hostile environments, environments with low oxygen levels, or environments that are toxic for an extended period of time. There are many different industrial applications that can be accomplished with these machines including confined space interventions, paint removals, asbestos removals, as well as tank cleaning. Using a breathing air cart or a compressed air system may be able to provide the breathing air.
Despite its limitations, it is still an effective and ideal solution for outdoor work where you don't have access to a power supply/a system of compressed air at medium pressure or access to a power source. This is a versatile and practical device that uses classic compressed air cylinders (SCBA cylinders) mounted on a cart for the purpose of providing compressed air.
