I remember these at Home Depot in the 90s. I kinda want one.

I just realized I posted the pictures in a backwards order! Oh well...
Anyway, I'd like to get the 16 inch version one day also, but they seem to be less common. I don't think they ever made a 9 inch model.

Very cool I love it. Other the the base that is different and the knobs placed differently it's made just like a 1990's Super. The 96 on the sticker inside the fan could make sense for the age of the fan.
I have a Super 40 cm desk fan that was bought in June 1997 and a 30 cm model from 1992. The new logo for Super appeared in 1998 or 1999.

Steel bearings will seize to the shaft if let run dry and you'll never break them free. The motor can be considered scrap after this happens. |

I could see it being from 1996, that means they would have gotten it the year I was born lol I don't think we have any Super fans here in the US, at least I haven't seen them...then again nobody keeps anything in this part of the country, so it could be that they've all just been replaced by now. |

Steel bearings will seize to the shaft if let run dry and you'll never break them free. The motor can be considered scrap after this happens. What's so bad about it? I saw one once, and only once, at a farm stand near my grandparents house, where the 12 inch one came from. I used to stop there and get corn before I went to their house all the time. The unit they had there was there for many years, its probably still there for all I know. It seemed very quiet. While I do oil this fan regularly, I never noticed the oil port, I'm not sure how I missed it I better get my act together. The cold season is on its way in, so I won't be using fan for a while. But, before I take it out for use next year I'll be sure to put some oil in the port as well to keep the wicks good. This fan has always had great bearings to it. |

The 16" uses the 12" motor, at least the few I had did. Mine was incredibly underpowered brand new out of the box, and the motor always got very hot. We bought three of them, two for the bedrooms and one for the livingroom. They all performed the same, poorly. |

I wouldn't be surprised if a lot of companies do that or don't enlarge the motor proportionally. Did they ever fail, or just run slowly? Mine seems to run pretty warm, the housing around the motor becomes warm after use. On my Galaxy oscillators, it doesn't get warm whatsoever. |

Yes, all three of them failed. They got so hot, they evaporated all of the oil away. Was it a bearing lockup or the motors burned out? One of them burned out completely. The other two seized up to the point where any attempt of freeing the bearings failed. I'm sure the evaporating oil problem was probably because the other two were at the point of premature burn out. They just progressively got worse. They continuously got hotter the more we used it. You could smell the oil burning off inside towards the end of their life. It started out when I only had to service them every year (A few years after brand new). Then they started to run slow so I serviced them for the first time from the factory and did a capacitor check with my meter. Then I had to maintain them every 6 months...and so on. I grew tired of it and eventually ran them into the ground after having to oil them every 5-6 weeks. I got one turning again, briefly....but the bearings spun with the shaft inside the motor housing, and it made horrible noises. I'm not one to neglect things either, these were maintained, cleaned and properly serviced with oil and grease...for the most part. This is how I discovered the steel bearings. Other than ball bearings, bearings should never be made of the same material as the shaft. If they were to run dry or overheat, metal transfers and basically welds itself together. This wouldn't happen with a brass or bronze bearing and a steel shaft, which is why that's what is usually used, material wise. Duracrap 16" fans suffer the same fate. |

I'm surprised they would make the bearings out of steel, that's really cheap. I thought even the cheapest of shaded pole motors at least have bronze bearings. Considering most people probably rarely, if ever, clean their fans, and I'm sure nobody oils them, you got way more service out of them than most people did. Just out of curiosity, about how many hours did you use them daily? The SMC that I have since ran nightly before I got it, so it has plenty of hours on it. At that point, there was nothing wrong with it whatsoever. The bearings must be different in the 12 inch. I haven't seen many 16" Duracraft fans around here, this is probably why. Again, this comes as a surprise to me because Duracraft is one of the few brands that still makes decent motors. I have 2 10" box fans from them, they're both still going after 4 or 5 years. They move a reasonable amount of air, never needed oil before etc. I think I paid about $20 for them, given you can get a 20" box fan for $15, I guess that would explain why they're not too bad. |

If or when you need to pull your motor apart, check the bearing color. If it's a dark grey gunmetal color, it's a steel bearing. They may not be different at all from the ones I had. One or both of the bearings may be this. I have come across many motors that will mix and match materials... I believe the reason yours is still working is because it's a 12". Less stress on the motor, it doesn't run as hot because it doesn't have to work as hard, so it doesn't bake all of the oil away. Those 10" Duracraft box fans use C-frame motors. C-frame motors are pretty generic, and while I don't like them at all, some last a long time and some give up their ghost rather quickly. They are fairly hit and miss. They're also prone to becoming lazy. For whatever reason, unknown, these little seemingly power-less motors will suddenly start to lose all of their torque and eventually reaching the point where they can no longer keep themselves going. Takes awhile for this to happen but it's certainly noticeable. They'll just take longer and longer to start and/or may never reach full speed, even if well oiled. |

Takes awhile for this to happen but it's certainly noticeable. They'll just take longer and longer to start and/or may never reach full speed, even if well oiled. I've had the motor open before to fix the medium speed. It never worked for as long as I could remember. When I opened the motor, I noticed that the wire going to the medium winding had become disconnected from the winding. Soldered it back on, and it was good to go. Though I would think my grandfather would have returned it for another one if it was broken out of the box, I have a feeling it has been like that since it was bought. It looked more like a manufacturing defect than a problem that developed over time. Unfortunately, I don't recall what color the bearings are. I'll have to put that fan on the list of things to take apart and check again. The fact that it has oil ports is very interesting to me, must indicate that this is a more upscale model than others? The Duracraft box fans do have C frame motors. They're sealed up more for being rain resistant, so the rear bearing is closed up, the winding is covered, etc. so they're not completely generic. I have noticed, probably since I got it, that the motor needs some time to warm up in order to run at full speed. When you start it up from cold, it takes about 5 mintues to get to full speed. If you turn it off, then turn it back on, it will get right up to speed. I don't think its a lubrication problem as it has plenty of spin down time. The motor itself is very quiet, I've heard good things about those fans lasting a while, so I'm not sure why its like that. |
