This is just one of many examples, I'm still looking, there are many to choose from. There is a patent on the way from a BBQ company that is going to make one for BBQ, ( maybe its the Guru company ? ) and of course cost more. Sort of what the Guru did. The concept is better than the current blower system because it sucks air through your bbq. So its more efficient, dont have to worry about leaks or sealant, as the hot air is sucked and maintained in and up the flue. The blower fans ( Guru, IQ) blow air, and heat out your pit if its not perfectly sealed, this wont happen with negative draft.
