Duty Cycle: What does it mean and how do you calculate it?

It indicates to the total time a compressor can work in a certain time period and a standard duty cycle is at 100 PSI and an ambient temperature of 72°F. This term is articulated in percentile figure such as compressor on time % (compressor on time + off time). For instance, if a compressor is rated for 25% duty cycle, then it means that it can work at 100 PSI and a temperature of 72°F for 10 minutes on as well as 30 minutes off. So, 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle.
