In which applications are pneumatic conveyors commonly used?

Pneumatic conveyors are specifically designed for the transportation of bulk materials in various manufacturing processes. They utilize air pressure or vacuum to move materials through pipes, making them highly efficient for handling powders, granules, and other bulk solids. This method of transportation is particularly advantageous in industrial settings where space is limited, and there is a need for clean, dust-free operation.

The versatility of pneumatic conveyors allows them to be used in a wide range of industries, including food processing, pharmaceuticals, plastics, and metals, where materials must be moved between different stages of production without contamination. Their ability to traverse complex layouts and minimize manual handling adds to their effectiveness in bulk material transport.

In contrast, other options involve applications that do not align with the fundamental purpose of pneumatic conveyors. For instance, transporting people or providing heating and cooling services pertains to very different systems and mechanisms.
