What type of system utilizes clean, dry air to operate pneumatic equipment?

Control air refers to the specific type of clean, dry air that is used in pneumatic systems to operate various equipment such as valves, actuators, and other machinery. It is essential for the air to be clean and dry to ensure the reliability and efficiency of the equipment, as moisture and contaminants can lead to corrosion, reduced performance, and increased maintenance needs.

In pneumatic systems, control air is meticulously processed and filtered to remove any impurities or moisture. This ensures smooth operation and prevents mechanical failures that could arise from dirty or wet air. The function of control air is primarily focused on controlling the operation of systems rather than participating in the processes themselves, which is why it is distinct from other types of air.

Relief air typically pertains to systems dealing with safety and pressure relief, while pneumatic air is a broader term that could encompass control air but lacks specificity. Process air usually refers to air that is involved directly in processing materials or reactions, which differs from the purpose of control air in operating equipment.
