Explaining Duty Cycle of Viair Automatic Portable Air Compressor for Class C RVs  

Question:

Helpful Expert Reply:

Duty cycle for a compressor is how long it can run compared to the time needed to cool down. So basically just think of it in increments of an hour - a 33 percent duty cycle over an hour is 20 minutes. And 33 percent at 100 psi is the duty cycle of the Viair Automatic RV Portable Air Compressor for Class C RVs # VA87WR.

So the # VA87WR can run for 20 minutes before needing a cool down, and since it will fill a standard Class C tire in between 45 seconds to a minute, there won't be any issues whatsoever inflating each of your tires in one cycle.
