FDNY COF to Operate and Maintain Air Compressors (A-35) Practice Exam

The duty cycle of a compressor is an essential factor that influences its operation, particularly regarding how long the compressor can effectively run before it requires a cooldown. Duty cycle is generally expressed as the ratio of the time a compressor is operating to the total time of its operation cycle. A higher duty cycle indicates that the compressor can run longer before needing a break, while a lower duty cycle suggests it must shut off more frequently to prevent overheating.

When a compressor operates beyond its designed duty cycle, it risks overheating, which can lead to equipment failure or reduced lifespan. This operational guideline helps ensure reliable performance and protects the internal components of the compressor from damage caused by excessive heat buildup. Therefore, understanding the duty cycle is crucial for maintaining proper operational conditions and ensuring efficiency in compressor usage.
