BEST ELECTRICAL TAPES EVER!
Scotch super 88: amzn.to/2qP1QJ7
The Super 33+: is just as good, just slightly thinner for more flexibility: amzn.to/2rKnrjW
How to wire a furnace squirrel cage fan:
White: common to one side of the plug
Speeds: (pick one for other side of your plug)
BLACK: HIGH
YELLOW: MEDIUM HIGH
BLUE: MEDIUM (medium low if Yellow is present)
RED: LOW
GREEN: GROUND(hook it anywhere on the metal body)
If it has a pair of BROWN or BROWN w/white stripe wires, these connect to each side of the capacitor that should be present. If you don't have the capacitor the decal on the side of the motor will say what size you need and they are very cheap.
These fans are designed to run with constant restriction. So you need to recreate this when used out in the open by blocking roughly 25% of the air intake or output. If you don't restrict the airflow the motor will pull significantly higher amps than it is rated for and will overheat/burn out. If you want to be scientific you can look at the side of the motor and read the rated amps. Then with a load meter ( amzn.to/2rhGYLK ) hooked up, run it and block off the air flow until the amp draw drops to or close to the rated amps.
Centrifugal fans are amazing at moving a large quantity of air and the output can be ducted unlike axial.

My dad has been using one of these for decades so I got to grow up learning engines with them cooling me, I still think they're very cooooool.
As a Plumber/Gasfitter here in Canada I use these fans for lots of stuff. They work really good for exhausting air or circulating air around. I also use them to thaw mobile homes to blow hot air from my salamander heaters down to the back of the mobile. They even work great in a house to circulate air from my wood stove in winter or draw in cool air/exhaust hot air in the summer. Works like a charm. That thick metal tubing you have is either z vent for gas or a flexible pellet stove interior liner. Great video as usual!
I love those blowers. I installed one in an enclosed trailer when I needed it as a shop and it about blew me out of there. The best thing it did however was blow all the saw dust right out the back of the trailer. Great tutorial!
That sounds like a great application.
I've used these as floor fans for years. Don't know why I didn't think of hanging in the rafters. Great idea! Love the multi direction tunes too!
It's nice to get it out of my way. Thanks.
Great video and information. I have a large one I'm making into an air quality/cleaner blower. I do woodworking projects and I'm getting ready to start the restoration on my 56 chevy in the same shop, so clean air is important. Thanks for the wiring help.
I've seen these around quite a bit and they DO move a lot of air. Your distribution system is genius. Thanks, Sixty-five!
Thanks.
Wow, I have a fairly new squirrel cage fan I kept from my old furnace when I had a new one put in. I remember thinking it would be good for something but kind of forgot about it and didnt really know what to do with it anyway. Thanks, this will be tomorrows project!
Awesome.
Now I see why you have so many subscribers, you have GREAT content! I was always afraid of those motors with so many wires, and you are the first person to explain it in 5 seconds!
We have a mobile auto repair shop, and I can think of a lot of ways to use this, THANKS!!
Thanks Man. -Moe
Thanks Moe, -Tim
,
That’s what you call good old fashioned American ingenuity! Great job friend.
Thanks, I'm glad you liked it.
Well Done !
Thank You !
I have two furnace fans I salvaged:
One from 1972 furnace - One from 1995 furnace.
The 1972 unit draws 15 AMPS (low speed : / and pushes air at 915 CFM
The 1995 unit draws 5 AMPS (low speed : ) and pushes air at 1230 CFM
Huge difference !
Think I'll put the older unit on craigslist.
Thanks for sharing the wiring information ! Saves a lot of head scratching !
Thanks Bob.
I have two of those, didn’t know why both only ran a couple of minutes and stopped, now I know. THANK YOU 🍻🇺🇸
I had one at my last shop when I lived on the bayou. man did that thing move some air. i need to get another for this shop.
They move a lot of air.
I have three at home. One I set up for my shop. Thanks to your video you gave me some different ideas for the other two.
That is awesome!
Thanks, I just had my HVAC replaced in my home, and they temporarily left my old furnace/blower in my attic. I'm going up there to salvage the blower now!
We use a large version of one of these (easily twice the size the one in the video) when remodeling rooms in our house. Position it so that it's blowing outside through an open window and all of the demolition/drywall/plaster dust is evacuated in a heartbeat.
I work on the side for Heat Contractor and every furnace we pull I take the blower home. After cleaning them up I have no problems at all getting $60-$75 a piece for them. The farmers around here love them for cattle and horse barns. Good Video!
I do the same. I blow the lint out, lube up the bearings, check for worn bearings and up for sale they go.
Those are centrifugal type fans. As the fan spins it slings the air out of the inside of the impeller to the outside. When it does this,, air is sucked into the inside of the impeller to replace the air that left. As far as the loading, the only way I can explain it is to think of the air as water, and the fan is a water pump. Restrict the amount of water in the pump, it has less to pump so less work to do. This is why your vacuum cleaner at home speeds up when you hold your hand over the hose or it gets clogged up. Wide open the fan is completely full of air, max load on it. Restrict the air, nothing to pump, less load, so it speeds up.
my dad and grandfather got a commercial fan like that from a building that was to be demolished in the 70s. After putting bigger bearings and a chain drive on it it was used as a pto driven leaf blower on our golf course. 24" fan with a 24x18" discharge. we had 60 acres lined with woods on 3 sides and had about 250 trees on the course. lots of leaves were moved with it and my dad still uses it to clear his yard in the fall.
Very neat!
Your channel is so awesome man iv seen most of your videos I'll probably end up watching all of them over time.
13 years as a traffic signal technician where taped wires can be left in place for decades, literally. Scotch Super 88 was what we used for most if not all the years I was there.
33+ is awesome as well
Great idea, I need one of those in my shop, already 90 degrees here.
They're impressive for the size.
Thanks, I am going to make one of those fans and I didn't know about the air restriction glad I watched this before I made one. And yes the super 88 is the best I have found also.
I threw away at least a dozen rolls of cheap stuff I had laying around. I was so tired of using electrical tape that fell off after a day or so. Now I'll happily pay more for Super 88 or 33+ .
Been using our old blower from our home furnace during the summer at our camp for about 15 years. Works great when you walk in & the place is 95 degrees from being closed up all week.
That's awesome.
I made one of those in 1995 and I've been using it ever since. even mounted it to a roll-around tool cart.
It's impressive how much air they can move.
I learn something everytime I watch you... the wiring was very informative ...no I know .. in Quebec Canada they had there worst flood in a hundred years so they need to ventilate so this is great
My old man was A construction/maintenance electrician for about 40 year's. All he used was 3M Scotch brand tape. Of course it was made in the state we lived in so we had to support the company!!
He even worked at the 3M tape plant on the east side of St. Paul just before his retirement in 82'.
It's great tape for sure.
Love it man! I have one in my shop too. Made an air cleaner out of it. Just in a box with furnace filters on 3 sides, rolling on casters.
Love your vids!!
Very nice. For woodwork, correct?
sixtyfiveford yes
i love the squirrel fan. i have a massive one that really blows the air actually to much air but I'm saving that for when i move and actually have a good size shop. As always great video my friend.
Thanks.
Fantastic. I finally got a minute to catch up on watching some vids. That 88tape is the same type I use. You get what you pay for and made in the USA! Crazy dog is back, yes!
Yep, Crazy dog never stops when the hose gets pulled out.
I have some small blowers I bought for around $50 each. One is a Stanley and another is a Lasko but they are essentially the same. They are great for moving air. They don't move as much as a furnace blower but we can easily keep it in our hall closet. We often take one on road trips for circulating air in the hotel room and drying swimsuits.
Those are nice units.
Awesome info touching on exactly what I needed to know about wiring it up. I also learned something new with restricting to keep it running correctly. I’ll think about the dimmer switch too
Hey Thanks.
You are da man. Racking my brain wondering why the blower won't work in a cooler for s..t. placed a restrictor on it and it works awesome. Thanks
An idea that has been around for a very long time. I have used them as
extractor motors when I am welding, brazing or even on a small scale
as a soldering station extractor. In my shop i have three of them with A/C
deflector to help spread the air around. Found and old commerical squirrel
cage that I use to extract air out of the ceiling which moves a lot of air.
They're handy for sure.
i have a tiny little one i picked up years ago and taped a metal tube to it, works great for livening up a fire.
Building a new 40'x40' shop. Have two of these that are wired 110v and extention cord. Picked up two more that are 220v. These will be permanently mounted and on a breaker. Thanks for the information on putting load on the blower. I did not know that. Great video!
Very cool!
good video .. thank you for the share.. i have actually been thinking about mounting some under my house to pull some cooler air in and a project to play with geothermal but my restriction would be on the intake side.. i hope people share and try your ideas
My grandfather has had ONE for 12 years now. works great
They're great.
I got one of them laying around know I know what I'll do with it. Get some air moving around the shop, great video man
Thanks Man.
this guy is fantastic every video as so much information...
Thanks Robert. -Moe
Informative as always.
I wish I could think outside the box ( fan ) more often. lol.
PaintSociety showed how to construct a cheap temporary spray booth and I think one of these might work.
Maybe too powerful? I'll keep it in mind for next year's paint projects.
On another note.
I won a running AutoTron 3300 at auction last week for $128 ( retail $2k ). Picking up after Thanksgiving.
I was shaping up to buy one of those $600+ jobbies from Amz too. Induction heater that is for rusty bolts.
This 3300 model can do more than that apparently - PDR, windshield and bedliner removal.
Always stay inquisitive you never know what you may learn!
Thanks for the video. Like you said, I was intimidated by all the wires. I have two of these in my shed I want to make fans out of to use at work.
I've done two of these myself. Highly recommend
I've been very pleased with mine for the past 15 years.
Been waiting for this vid, got a fan ready. thanks again.
Thanks for watching.
Great ideas! What is the red tool you used to cut the sheet metal for the exhaust tubes? I've been looking for something similar to use on my projects.
Another great idea, as always, great and useful info.
Thanks.
Thanks Man.
propeller fans compress air as well, just not nearly as much as a squirrel cage does. thanks for sharing this video, very useful!
True. Propellers need a proper clearance housing/shroud and they work well at compressing.
Just what I wanted to see how to do! Thank you. Your video was just perfect A+.
Glad it was helpful!
Awesome video for repurposing stuff. Love it. Knew there would be something cool to do with old part to HVac and thank you before I just ripped it apart:)
It looked like one of those ocean snails, with the four air outlets. On a serious note, what a useful project. I hope I can find one free to make a stand alone blower.
Drive by some HVAC service shops and pop in. I've never had a place turn me down if they had them. You'll generally need a 5/16" and 1/4" nut driver or socket/ratchet and something to snip wires and they pop right out.
Another good video Moe.
Thanks Jimbo.
ok i have a very important question that i hope you can answer. that fan of yours with the dimmer switch. how do you wire that up? do you have a video showing how or could you make a video showing how?
Great video and informative.. thank you
Have one I've used in the shop for years and have it set up on a three foot stand which allows me to direct the air flow where I'm working .
Nice setup!
Love that dog at the end.
She's always having a great time.
how do i hook up the capacitor to the plug?
Hey 65, I miss all the stuff I used to get like that, just going out at night, garbage picking. That was a traditional rite of passage for tinkerers and other hoarder types like moi. Where I live, now, in northern PA, everything either goes in a pile and turns to rust because it is so wet and humid up here, or goes up to New York State for scrap. There are no entrepreneurs who like to turn junk into jewels, up here in these hills. Hey, I am a poet and didn`t know it.
Well said.
I have made 2 of these things so far. One for an air filter for wood working and another for when ever i get around to building a coal forge (this was a real small one out of a window AC unit).
Will eventually make another for a fumes fan for welding.
I've kicking around the fume extractor for quit a while now.
Yeah you just have to be careful you aren't sucking your shielding gas. The small one i pulled from a window ac would more than likely be plenty on medium setting.
I just learned why my blower turned shop fan cycles off and on. The motor is getting too hot, thanks for the education. I will add just a bit of intake restriction as you demonstrated.
I've had to block upwards of 75% of the one side on some to keep them cool.
these fans are designed to work in a box... like you’ll find them mounted in a furnace. in a box, some air will pass through both sides, cooling the motor. run wide open (unrestricted) on the input side and restrict the discharge side. adjust the discharge while watching a clamp ammeter- metering power consumption. you will hear the speed jump up when you hit the right amount of restriction, and the amps drawn will be at a low. the fan is now balanced for performance, which will ensure a longer life. remote the capacitor to the outside of the fan cabinet for easy service- the starting capacitor should crap out long before the fan motor.
As always, excellent how to video my Friend! Cheers Moe! Zip~
Thanks Man.
Thats all we ever used, and they work awsome
They're awesome.
i just got out of my hvac/r training,certification; so when i saw this i clicked on as soon as possible because i was intrigued and curious how you would go about it (mostly concerned with how they should have a load on them. in the shop we usually just stick a peice of sheet metal over the one side and they run great)
but this brought up something, wouldent having a variable resistance switch cause the fan to be undervolted? i know that it can damage compressors and three fase anything but how would that affect a single fase electric motor such as these? dont remember if this was ever discussed in my classes
I've had no issues running it with the rheostat as these motors don't have a constant load like a compressor motor. The slower they move the less load the blades take. That being said, I generally run it on full power at all times.
Great idea using the small tubes to direct the air flow.
Thanks. It has been working very well.
Great idea! The heat is on.
Thanks Man. -Moe
Can you recommend a speed control switch or is it even worth the effort?
Great informative video glad I found it. Just squired one of these fans. The first one you showed had a variable speed dial. How can I hook that up w/ 4 speed wire set up? Thank you do you have another video that shows it
The variable speed(light dimmer) is just hooked in line with the power wire. I don't find it very useful and wouldn't go out of my way to do that again.
that gives me an idea for a welding fume extractor! thanks Moe!
I've toyed around with this idea for a few years now. These have great suction through the side and could easily be adapted with flexible dryer hose to suck welding fumes.
exactly what i was thinking
The Moto fixery. marijuana exhaust fan
Moe, thanks for another great vid.
Thanks man.
Hey Sixtyfiveford I'm curious I am picking up a industrial squeral cage blower today 1hp and it has a capacitor attached to it with the 2 brown wires like you said. Now it's 240v. What does the capacitor do and can I operate it without it? Thanks so much.
AWESOME TIP ON BLOCKING OFF A PORTION FOR COOLING IT GOOD JOB
Thanks Drew. -Moe
What will you think of next! Amazing man! Thanks for the video.
Thanks for watching. -Moe
Not really been making these since 1981
The best shop squirrel cage fan I had was from a server rack, It really moved some air quietly. Lost it after a move. There is an HVAC shop within sight of my house, time to stop by!
I had a huge one that was 4x the size of this little guy. It felt like your hand was going to get pulled in if you got to close.
Awesome idea!
Thanks for watching.
You are so freaking clever!
Thanks Amy! -Moe
I got one sitting in My garage for ten years now. I'm thinking of retrofitting a furnace filter in a box (cardboard, steel, plastic, etc..) with the blower to use as an air purifier. It would clean out the air in a large room in no time flat.
The dark blue motor sorta has the same design of the motor from a bernes Air King.
Great vid. I like your dog too.
Thanks. The dog is always having a great time.
Love it!! What fun that would be to make......and ya made it look easy too Moe.
Thanks.
I made one of these and really like it.
AWESOME. They move a ton of air.
I watch how you make those four holes. What tool is that? It cuts the metal fast. Also I have a question, my wood/metal/plastic scroll 16" been unused for 15 years,
. I oil it and check it out. Not working!! I contact dremel company. They said no parts available since 2005. So I took it apart and the motor has 4 wires. White, yellow, red, and blue. If I want to wire it to white and black cord, to see if motor is good or not. Motherboard sitting next to it. I am not worried about the motherboard as I am not going to used them. Just the motor if it works. How do I wire them? What colors?
my garage has a wirly bird type vent in the roof i have a furnace blower mounted to the cieling venting up and out the wirly bird , does a great job extracting the heat from the garage during summer time while im working in there
Nice setup. I have a whirly vent on my garage roof as well. I mainly use the rafter fan to blow fumes out of my face.
I changed to Scotch electrical tape a year or two ago. I don't care if it cost more. It works and is not frustrating to use. Squirrel cage fans are great. I have a small one that I use when working under a car. I use to live where there were to many mosquitoes. Drive you nuts without fans. It was even worse under a car. That fan would keep them off while working. Plus they can take being banged around and they don't tip over like a box fan.
Bug control... Good tip. Yeah, I will pay a little extra for tape that actually works. I threw away a dozen rolls of off brand stuff the first time I used the amazing Scotch tape.
Great idea!
Thanks George.
Good idea to share . That dog is a hoot. LOL
Good idea. Thanks for the video.
You bet
Can a 220/240v fan be wired the same way?
I wired mine up but needs assistance to start spinning, does this mean that I need a capacitor for it? Also, will a 370/440v capacitor work if I’m using 110v? Another great, helpful video as always. Thank you!
Straight to the point! I was NOT disapppointed you didn’t start out with 30 seconds of useless graphics and music!
Thanks, I'm glad you liked it.
Nice video in Arazona they use then as swamp coolers and they have water dripping into them to put moister back into the air. Dry hot in arazona.
Yeah, I use a swamp cooler up here in Utah.
Great video, 👍🏻 you look like the guy on contra game
Good old Contra. I spent many hours playing it.
i think i'm going to put one of those on the vent in my attic to suck air through in the summertime to keep the house cooler
I just had our furnace and air conditioner replaced and I salvaged the blower. I use that thing all the time to blow the airborne sawdust out of my wood shop to great effect. I just acquired a second one which will be used for drying things.
Awesome.
I like the idea of putting hoses on there where you can direct the air in different ways. Seems to put out a lot of air.
It seams to work very well. I had an identical unit in the same spot last year but it just shot straight down. It was great for getting the Carb cleaner, paint, etc fumes out of my face if I stood directly under. It'll be nice to be able to stand almost anywhere and have fresh air.
I use an old swamp cooler motor and cage. Same thing ....two speed also...swamp cooler on casters its about 3" off the floor...bucket of water in it and it works for a while....til the humidity rises to the point that evaporation has saturated the air....actually works better when doors windows are open.
Thanks for the tips.
Thanks Man.
Nice
just got 3 of them
Didnt no none of that
Thanks for the infor👍🏽👍🏽👍🏽👍🏽
Thanks for the information. I just picked up an old 110 blower w/capacitor furnace motor. I did not know about the restriction requirements so appreciate the important information. Thanks!!
Thanks, I'm glad the video was helpful.
I have a small black one from a bathroom vent I use by my bed and it works good.
Great info so that is why mine is.doing that. Thank you.
Thanks.
Great info, thanks!!!
