Which of the following is a common sign that an air compressor is overheating?

• A. Low noise levels
• B. Discharge of warm air
• C. Fluctuating pressure
• D. Increased lubrication needs

Answer: (B)

Discharge of warm air is a common sign that an air compressor is overheating. When an air compressor operates, it generates heat as a byproduct of its mechanical processes. If the compressor is functioning correctly, the expelled air should be cool or at least at ambient temperatures. However, if the air being discharged feels noticeably warm or hot to the touch, it indicates that the compressor is likely overheating. Excessive heat can be a result of a malfunction, lack of proper ventilation, or insufficient lubrication, which can further lead to reduced efficiency and potential mechanical failure. The other options may have their contexts but are not typically direct indicators of overheating. Low noise levels may suggest that the compressor is functioning normally or could be an indication of malfunction rather than overheating. Fluctuating pressure often relates to other issues such as leaks or problems with the pressure switch rather than specifically to overheating. Increased lubrication needs could indicate wear and tear but aren’t a direct symptom of overheating; instead, they signify the need for more frequent maintenance.
