What they said was SOME ran for 8000. They quoted the best scenario. Did they actually run 100 and 1 made it here by luck? Was it component bench testing extrapolated and not the whole unit really running under normal conditions? Did most fail at something very much less than 8000? What is the average? What if it's 3000 hours average, do you care SOME made it to 8000? Don't fall for the marketing unless you are buying from me.

However, to prolong the life of your air compressor, it is recommended that a 50%-75% average duty cycle be maintained; that is, the air compressor pump should not run more than 30-45 minutes in any given hour." But I have to agree, 8000 hours for the motor and air compressor is impressive, if that's accurate. Craig L.
