Why might an air compressor surge?

• A. Due to over-lubrication of components
• B. Due to malfunctions in the power source
• C. Due to restrictions in airflow or improper sizing
• D. Due to a decrease in air temperature

Answer: (C)

An air compressor surge typically occurs when there are restrictions in airflow or when the compressor is improperly sized for the application it is being used for. When the airflow into the compressor is limited due to blockages, such as dirty filters, closed valves, or undersized piping, the compressor may not be able to maintain a consistent and adequate supply of air. This can lead to increased back pressure and unstable operation, known as surge, where the compressor struggles to maintain its flow and pressure levels. The importance of correctly sizing an air compressor cannot be overstated, as selecting a unit that is too small for the pressure and volume requirements can lead to similar issues with surging. Hence, ensuring proper airflow and correct sizing are crucial factors in preventing compressor surges and maintaining optimal performance.
