September 30, 201510 yr Does anyone have a recommendation on a good coal forge blower to put on my 2" air pipe? What is a good CFM for that size?
September 30, 201510 yr Old hair dryer, old bath fan, fan from one of the power vent water heaters, shop vac, leaf blower. list goes on and on...Soft coal doesn't need a ton of air, so just about anything that blows will work. Anthracite likes more air and a constant flow, you you want to tend towards a slightly bigger fan, but you don't have to go crazy.
September 30, 201510 yr I have been using a $16 bathroom fan from HD for over two years...still going strong. Used several hours each day, 4-6 days a week. Quieter than a screaming hair dryer...those are bad enough with the wife using one.
October 1, 201510 yr Author Ok cool, I think I'll look for the bathroom fan then! xxxx i threw a power vent away recently, dumb.
October 1, 201510 yr Yup, cheap bathroom fan here, have a fan speed control on it, works just fine, nice n quiet.
October 1, 201510 yr Ok cool, I think I'll look for the bathroom fan then!damn i threw a power vent away recently, dumb.if you have Harbor freight stores near you or order on line. http://www.harborfreight.com/3-speed-portable-blower-61729.html works very well and the description isn't accurate. the one I bought was variable speed with a rheostat and nice an quiet. a floor register duct reduced the rectangular exhaust opening down nicely. I think rated for 300 CFM at max
October 1, 201510 yr If your willing to part with around $65. The one I use works perfect for my coal brake rotor forge it's the dayton blower 1tdn6. I looked up my part# and it changed to this one ^. As you seemed to be looking for a quiet one before it is super quiet and I run it off a variable speed switch I picked up at harbor freight. With the switch I rarely over 3/4 so its powerful enough. I have no need to run it on full. Plus side is mine fits right in the screw flange on my 2" pipe so I don't even have to attach it with anything, it just fits right in there. Simple. :)
October 4, 201510 yr Author I bougth a bathroom fan blower and it works good enough for now. i think I'd like some more cfm. The one i got pushes 70cfm. The harbor freight fan looks interesting with the three speeds. I also have the brake drum style forge.
February 28, 201610 yr I use a champion crank blower no idea what the CFM is but they make (made) different sizes for different forges. 10 12 14 and 16 I think? My last bathroom vent blower was 75/80 dollars. Some think that is inexpensive? I guess it's where and how you live.
