You didn't provide all pertinent info available to you. Lets take what we have; and, consider why your compressor is overloading the circuit breaker. Points to ponder:
Not knowing the exact model (not series) I don't know what the amperage pull is for your "extreme" compressor or the circuit breaker's rating. A 25 amp compressor connected to a 25 amp breaker could be an issue. Campbell Hausfeld's support pages are crashing so I can't check the possabilites.
Are you using a lightweight extension cord? The lower the rating of an extension cord the higher the amp pull on the breaker. If you eliminate the extension cord does the problem go away? Ohm's Law applies. <http://www.ohmslawcalculator.com/ohms-law-calculator>
What else is on this breaker? Is there other high-amp equipment in another room (water cooler, window air-conditioner, portable electric heater, etc.) pulling from this same circuit breaker.
Is the circuit breaker not performing to specification? I've seen failing breakers trip early.
First, check the owner's manual for power requirements. Next step, use no extension cord; and, insure nothing else is pulling power on that breaker. Then, use a different breaker and see if the problem follows the compressor. If all else checks out than I'd consider binding in the compressor causing the amp pull to be too high.
