DAYTON blower

[GramaCindy]

http://www.grainger.com/Grainger/DAYTON-Low-Profile-Blower-4C826I was able to get this blower for my 2x4 Mason with a 14'- 6" flue pipe. It looks to be 200+cfms. Will this work okay?48384839

I'd like to attach a switch or at least a rheostat. Tim says he may be able to do that. Any suggestions would be greatly appreciated. Thanks! Cindy

I've been told that blowers work best and last the longest if they are running full speed. I had mine on a rheostat but now run it full speed with a damper in the duct work.

Thanks Jim, I have been reading that alot also. Will keep in mind when we install the blower.

The best way to regulate flow is by putting a baffle on the blower inlet. It actually reduces the load on the blower as well as flow rate. See this:

You don't need to get that fancy, just block off the inlet with a scrap of plywood

Riley, won't that speed up the process of burning out the blower? Overheat, etc? and, I really hate to have to squat down to the floor where the blower will be each time I'm going to load wood into the fire, to crank it down.???

The fans do not cool the motor. If you have no air being sucked in then it will have none to blow out so little to no resistance/load on the motor.

I can't remember off the top of my head but there is a certain type of AC motor that you can adjust the speed with a speed control, Shaded pole comes to mind but not 100% sure. Other AC motors can be varied with a speed control but will not last vary long.

I agree with the others use a shutter plate on the inlet to the fan to adjust the air flow out to the evap.

Thanks Dennis H. We will work on some sort of contraption to close off the inlet. Part of the fun of sugaring for sure!
