Hey Folks,
I picked up a couple of blower motors from some gas furnace. I think they are called draft inducing blowers. They blow the fumes from the burning gas up the flue of the gas furnace and out of the house. One of them is 1/20 of a hp and the other is 1/25 of a hp and are both 110. One of them I got from an air conditioning repair place from a bad unit and the other I got from the junk yard from a bad unit. Both $0 :thumbup:

How can I figure out how many CFM's these might produce? As long as I can get them connected to the 1" pipe, will either one of these work for a blower for a burner?
Thanks
