Golden 12” Industrial Ventilating Fan

You know those Chinese-Asian extra strong industrial exhaust fans that have the 4 backwards ‘D’ blades & cast metal cone shaped hub? I’ve had that fan in my wishlist since I was a small boy. I love the muscular looks from the 8 sided frame, wide beefy blades, and the big fat motors that drive them. Well, I’d never been able to afford one of those fans because of their hefty pricetags, even when used. But earlier this year I found the fan I’d been looking for all this time, only the thing is, it was in pretty bad shape. For one the iconic bladeset that originally came with it is gone, and later I found out the seller’s attempt to replace the original bearings which he said wrecked the original blades that were stuck in place made the shaft bend between the rear bearing & rotor. As a result of him swapping the original heavy duty fan blades to a flimsy aluminium fan blade he dropped his asking price, and I got this thing for really really cheap.
Golden isn’t a brand that I’m familiar with. So because of that, and because this is my first heavy duty exhaust fan, I immediately tore it apart to learn its guts. As it turns out, this fan is probably one of the crappiest extra strong exhaust fans available. The shaft on this thing isn’t properly hardened, so a hard tap from a hammer will bend it no problem. The rotor is warped in a really weird way from the factory, and the motor insulation are loose in some spots. But because I got this thing for cheap, I can’t really complain.
Conveniently, I made a low noise//high presssure fan blade just days before I unexpectedly purchased this fan as an experiment. So after I managed to remove the bodge job crappy fan blade the seller put on this fan just so he could sell it, I installed my experimental fan blade, and it worked brilliantly. Sure there is a big gap between the fan blade & shroud which annoys me & probably you too and it doesn’t look that good from the intake side, but for what I have planned for this fan, it’s good enough. Plus I now have a high preassure exhaust fan which makes me happy, so that’s a plus.
And because this fan already has new holes drilled into the body by the previous owner & its blade is no longer original, I decided that this fan won’t spend its life on a display shelf & that I’m free to use this fan for any experiments. One change I’ve made that you might have noticed is the pullchain switch. Although this fan has deeply pitched fan blades & the number of blades don’t match the number of motor brackets, I still think its full speed is waaay too loud. Originally I wanted to just choke power coming to the motor with a capacitor & leave it as it is, but then I thought what if I need this fan to run on its full capacity. So I thought I’d install a ceiling fan pullchain switch on the motor, wire position 1 to run on full speed, leave position 2 empty, and wire the 3rd position with a capacitor in series. But then an idea popped in my head, why don’t I use the leftover switch position to make the fan run on intake, I might need it right? So after some thinking, I wired the switch as such so that the first pull gives you full speed on exhaust, 2nd pull gives you low speed exhaust, and 3rd pull gives you full speed intake. On low exhaust this fan moves about the same amount of air as my New Star 12” exhaust fan ( • New Star 12" Industria... ), but makes waaaaaaaay less noise.

Nice fan! Here in India , these fans are commonly seen everywhere. They have 4 'D' shaped blades with a cast aluminum cone shaped hub with 4 shanks for each blades. These fans are mostly manufactured by Crompton Greaves ( now Crompton) and another brand called Almonard . Their motor label information says " Ac Propeller type Ventilating fan". Its available in size 6" 8" 12" 18" 24" and 36" . 24" size comes with 6pole 3ph 900 rpm motor and 36" comes with 8pole 3ph 700 rpm motor and rest of the small sizes comes with 4pole 1ph 1400 rpm motor but 6" comes with shaded pole non bearing motor. These fans are pretty loud and makes a feeling of a real industrial fan!

[@TheFanUniverse]

It is! This fan used to have that 4’D’ bladeset, but the previous owner wrecked it so I had to make a new fan blade for it since the blade it came with is off of a household fan. It’s one of my most favorite style of modern industrial fan, not only because of the muscle-y looks, but also the sound it makes

[@antiquefanworld1728]

@@TheFanUniverse Oh! Try to get the blades which looks similar to the original blade set or just get the casted cone hub and just make the 'D' shaped blades out of plain aluminum or steel sheet. The favorite part is the frame design and obviously the blades too look cool . Sounds like Antonov An-22 Turboprop. The motor of the above mentioned fan (golden industrial fan) looks similar to GEC Expel air fan which was sold in India way back in the 90s time. These type motors are fully enclosed rather than other ventilation fans with vent holes in their motor. With original 'D' blades, it would give out a loud humming bass which would make you really satisfy the feeling of powerful industrial fan!

[@TheFanUniverse]

I plan on installing this fan in my house, and I'd rather have this homemade bladeset stay on it as I don't want the fan to make excessive noise, that's also why I added a low speed setting. In the future I will probably buy one in better shape for my own collection.

How did I miss this upload, I was almost wondering why you hadn't posted this week! Neat fan, love that pullchain mod with the reverse mode. The switch location actually suits the fan quite well. I think it nicely fits what otherwise would have been a plain motor cover. The overall appearance seems to mildly resemble ILG fans, but maybe it's just me lol.

[@TheFanUniverse]

It’s probably because I tend to forget to post that “Hey look I’ve just posted a video on KZbin!” thing on Insta story lol. Thanks! That switch is placed there because of a lack of space inside the dome. I had to jam in a new capacitor over the terminal blocks & run cap, and the only space left for the switch is that center area of the dome. If it weren’t for that, I would’ve placed the switch on the bottom of the dome so it faces down, making it easier to pull. But I think I have to agree with you, it looks better that way haha. As a big fan of ILG fans, that was actually the first thing that came to my mind when I saw this fan. With a circular cast metal shroud & 1 less motor bracket, this would look almost like an ILG exhaust fan

[@TheSuperFanMan]

It’s all on me, I got the YT upload notification but I’ve been busy so I must have somehow missed it lol. The bottom location actually does seem to be more practical for the switch, though I would think the difference in the ease of pulling is pretty minimal compared to the rear mount.

@@TheFanUniverse Your welcome no problem

Sounds good. Definetly much quieter then the original blades. I have a roughly 24 inch one in my house and its way too loud

[@TheFanUniverse]

Thanks! I was very dissapointed when I learnt the original blades were missing, but once I threw the 3 deep pitched blade on it, I’m actually quite happy haha.

[@Theutmostgeek]

@@TheFanUniverse I bet it performs better too. It would probably also have a heavier blade since those exhaust fans with the D blades tend to run not very fast

It's quite an unusual fan with the pullchain
