JacksonBower123 Posted September 18, 2022 Share Posted September 18, 2022 I have a box fan that is about 1 ft by 1ft by 6 inch it can produce 430 cfm but I can’t focus the airflow into a forge either having backflow or air blowing out the side of any entrance tunnel I try to dig into the foundry which is built into the ground. I’m wondering how I can attach and funnel the airflow into a pipe for more air pressure into my propane foundry. I don’t know if it is doable or if I should buy a fan that can achieve higher pressures. AC Infinity AXIAL 2060, Muffin... This is the fan for reference Quote Link to comment Share on other sites More sharing options...
Latticino Posted September 19, 2022 Share Posted September 19, 2022 I wouldn't use that type of fan for a forge blower unless I had no other choice. That fan is optimized for high airflow at relatively low external static pressure (probably on the order of 0.1 inch WG). You want the opposite for a forced air burner fan. If I had to use it I would construct a shroud on the fan outlet that transitions from the 1' x 1' size down to 2" diameter at a maximum of a 30 degree angle from horizontal (something like below, but much longer). I would minimize the duct length at the 2" size and no use elbows unless absolutely necessary. Honestly, for the effort involved, you are better off finding a better option.

Jobtiel1 Posted September 28, 2022 Share Posted September 28, 2022 Good stuff, that should help you out when it's summer again. Or do you still have those insane temperatures over there. I can confidently say that summer in the Netherlands is over. It was a fun two months. ~Jobtiel Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 28, 2022 Share Posted September 28, 2022 Only supposed to be in the 80's degF this week; finally! (appx 26-28 degC) Quote Link to comment Share on other sites More sharing options...
Jobtiel1 Posted September 28, 2022 Share Posted September 28, 2022 That's prime summer temperatures! We are currently at the 14 degC (57 F) already. While it will clear up a bit next week, autumn really has started. ~Jobtiel Quote Link to comment Share on other sites More sharing options...
TWISTEDWILLOW Posted October 2, 2022 Share Posted October 2, 2022 Here to, the days have been in the 80s but the nights are dropping to the 40s so it’s making for some nice cool mornings in the shop! Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 2, 2022 Share Posted October 2, 2022 You can always light up the dried leaves on the floor for an early morning warm up! Quote Link to comment Share on other sites More sharing options...
TWISTEDWILLOW Posted October 2, 2022 Share Posted October 2, 2022 Lol Thomas, I actually already did that, cleaned out the smithy this week put all the leaves in a big pile and burned em one cool morning Quote Link to comment Share on other sites More sharing options...
Frosty Posted October 2, 2022 Share Posted October 2, 2022 If you used a small leaf shredder blower thingy you could feed dry leaves, grass and such to your LP wood stove in the shop like a gas burner for heat. You'd want to mount it vertically and aim the fuel air so it makes a vortex. The fire burns against the shell of the stove. Know anybody with things like old dead leaf blowers, forge blowers, etc. that could be converted? Heck, it the dead small power tool pile had a wood chipper in it a similar stove could be fed dry wood chips with an auger. There are details for things like the smoke stack, lining, etc. and ways to turn it into a multiple burn zone wood gas furnace but a 100gl. propane tank would be about perfect for an old drafty shop.

ThomasPowers Posted October 2, 2022 Share Posted October 2, 2022 TW's shop: no walls, no roof, no doors; so a tad drafty---a big plus in the summer! Quote Link to comment Share on other sites More sharing options...

TWISTEDWILLOW Posted October 3, 2022 Share Posted October 3, 2022 That won’t be here till next spring Thomas, don’t have tornadoes in peavine during the winter months Sheesh, I’ve only lost my shop roof one time… you act like that’s a regular occurrence round here, Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 3, 2022 Share Posted October 3, 2022 Remember I've lived in both OKC and Fayetteville and so I know what the climate is like your way... It will be interesting to see what the cotton wood cotton will do with the BIG FAN working next year! Quote Link to comment Share on other sites More sharing options...
TWISTEDWILLOW Posted October 3, 2022 Share Posted October 3, 2022 You could blow em all up in a pile an then set me on fire with that fan fueling it! Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 3, 2022 Share Posted October 3, 2022 I can set them on fire just dropping a lit match onto the floor. With the fan I might be closer to a "dust explosion" scenario. Quote Link to comment Share on other sites More sharing options...

Frosty Posted October 4, 2022 Share Posted October 4, 2022 Good point Das, that fan will be a world class critter catcher! Better get the scree the right mesh, critters hitting the blades could get messy. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...

Frosty Posted October 4, 2022 Share Posted October 4, 2022 I'll bet it irritates the shop critters having to slow down to scurry around outside collecting cotton wood cotton to replace what burned out of their comfy soft nests.

TWISTEDWILLOW Posted October 4, 2022 Share Posted October 4, 2022 Thomas, you need to find critters that will eat the cotton wood fluff not bring more in! Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 4, 2022 Share Posted October 4, 2022 Hoping the Barn Cats will reduce the shop critter population this winter. I'm thinking of putting in a cat door in the clean shop; but I need to keep them out of the forge shop as the nice dry sandy floor encourages them into bad habits!
