This is the funniest thing I have read in quite some time. An overpriced draft fan coming years too late.
It is a joke right. The Bejing thing was the funny part. That and the prices.
Of course maybe not... I used to think I needed something bigger than my 25 cfm for my stoker and Brazos pit but with 50 cfm I could melt lead and make pizza. 25cfm gets me 500 degrees but that's due to my air induction routing.
