Corey, There are several possiblities to discuss. I suggest you phone me as I have several questions to ask so I can understand how you are running the two setups. First, it needs to be determined whether or not you in fact have rotor loss. Simply the number four light blinking is not proof positive you have rotor loss. The only way the AirJet chaffer can contribute to rotor loss is if it overloads and runs too much into the returns system. In that case you would also have excessive chaffer loss. Alternatively, you can move the AirJet to your other machine and see if the condition follows. My phone number is 1-800-745-1680.
