What is the primary benefit of using an air receiver in a pneumatic system?

• A. Increases the color of air.
• B. Filters air more effectively.
• C. Dampen pressure fluctuations and supply peak flow, reducing compressor cycling.
• D. Adds lubrication to air.

Answer: (C)

A storage reservoir in a pneumatic system smooths out the flow by buffering the air supply. When you have devices that suddenly demand a burst of air, the receiver provides that immediate peak flow from its stored air, so the system doesn’t drop pressure too quickly or force the compressor to start and stop every time a tool is used. This buffering keeps downstream pressure more stable, reduces the number of compressor on/off cycles, and improves overall efficiency and equipment life. It’s not about changing the air’s color, filtering, or lubricating it—those are handled by other components. A receiver’s primary job is storage and buffering to dampen pressure fluctuations and supply peak flow.
