What is the function of an air receiver in a pneumatic system?

• A. To Compress Air
• B. To Store Compressed Air and Damp Pressure Fluctuations
• C. To Filter Air
• D. To Regulate Temperature

Answer: (B)

The air receiver’s job is to store compressed air and smooth out pressure changes in the system. By providing a reservoir, it keeps a ready supply of air for when a tool or actuator suddenly demands more, so downstream pressure stays more stable and the compressor doesn’t have to start and stop as often. It also helps damp pulsations from the compressor, which makes flow steadier and protects valves and actuators from pressure spikes. While filtration, moisture removal, and temperature control are handled by other components, the receiver itself mainly holds air and stabilizes pressure. Condensation tends to collect there as the air cools, so a drain is used, but the key function remains storage and fluctuation dampening.
