I use the larger cfm rated unit on a bottom draft coal forge. In my opinion it works well. Only drawback being that it doesn't do low end very well.


Does anyone have experience with using a rehostat on these units? Single phase operation using voltage reduction has some heat issues. Also keep in mind these are Chinese motors. K&S does not recomend going with a rheostat but I was still curious if anyone has tried this arrangement and I if so, what their findings were.

I would like to get a better low end out my own arrangement.

I built a slid gate to use with mine and just leave the blower running on full power. Functional this setup works very well and allows excellent control over the blast. I also installed a switch on forge so I can turn the blower off in between heats. The fire does not loose much heat while I'm at the anvil. This saves a bit of fuel and I don't have to listen to the blower running constantly. I can comment on the use of a rheostat but if the motor is overheating a slid gate would be a good alternative.

Kubiack, Thomas,

 

Using the ash dump puts too much dust and ash into the air.

 

I do use an air gate and I throttle the fan (casing) inlet somewhat.  I also have a switch handy on the forge to secure the blower, which is usually what I do. The dynamics of the coal fire, seems to favor fast and furious over low and slow.
