New Oscillating Fan with pole clip

OK I hung all three fans in my shop on slow of 2 speeds. The speed appear to be the fan blade speed.

The only UL marking I could find Rik anywhere on the fan was the pressed in line of information into the cord itself and that is hard to see. There are no DO NOT remove labels found on the cord nor any marking anywhere on the body, blades, screen frame or clamp. Nothing, nada.

So besides to UL mark on the box that’s it.

If these fans haven’t burned out or up in a couple weeks I’ll hang them in the tent at the angle they were meant to hang. I figure the angle they are hanging at now should test there strength.

Thanks MrPNW for that info. I hate to say it but I suspect the cord is the only part that is UL listed and that the fan itself is not. If it were me, I probably wouldn’t use it.

I just bought one of these and put it in my tent:

https://www.vornado.com/shop/circulators-fans/oscr37-37-oscillating-tower-circulator

It’s sold out on Vornado’s website but you can get it on Amazon for $90. We’ll see how it holds up. It is ETL listed and I like the Vornado brand.
 
One of my work duties is the ordering of equipment from computer related to fans for 75 staff. Years ago I bought everyone a Vornado VH101 750w desk fan. I bought that model for years without a problem.
Then in 2018 we were told to collect them all, due to a recall, and purchase the replacement model, the VH200. I got a shipment and within 4 months they all started dying, just stopped working one after another. For whatever reason they chose to replace perfectly working ones I don’t know, but to replace our working fans that ran year after year with something that broke so soon after I stopped buying Vornado. Had it been a single fan I probably wouldn’t have been so angry with the company. Yeah I know it was still under warranty but what a hassle, I just moved to buying a different brand.

Now after boring you with my fan rant Rik, I am interested in the longevity of that model from them.
 
I don’t have a Vivosun fan but if anyone does, can you look at my photo and tell me if it looks like Growbuds may have done a deal with them and just did a black version with their logo branded on it?
 
do you think that because it oscillates 180 degrees, that could be a problem? most people clamp the fans on the tent poles, with only allow 90 degrees. i had two on the vivosun, they both lasted about 6 months. i use there clamp base, for some non oscillating fans.
 
It sure sounds like the next great feat in the cannabis grow world will be to market a pole mount fan w/90 degree oscillation that is UL certified and can stand the test of time.
 
I’m going to contact Holmes, the maker of my blizzard fan and let them know the opportunity they could have. My blizzard is the perfect candidate for this.
 
I just read on the Vivosun site, that they are out of stock now and that the fan is being upgraded. The illustration of the motor shows the parts being stronger and long lasting. It says the fan can do both 90 H and 120 V pattern. Was that always the case? I wonder if they are attempting to UL approve it?

So this seems to be what is being upgraded. Would someone be willing to open a broken Vivosun to show how those innards differ to this new illustration?
I’m thinking Growbuds talked with the manufacturer of who made the Vivosun fan, got them to address the issues, had them make it in black/w logo and released it this year. I’m not seeing any real differences to my Growbuds fan to these photos on Vivosun’s site.

I may just open one of mine in a couple weeks if I have some pictures of what was changed. The illustration says new bearings. So is that ‘new’ as in never had them before or as in upgraded bearings from inferior quality?

Yo dude, just to let you know, Rik is totally correct - only the cable is UL Listed, none of the rest of the fan. UL Listed cable is cheap as chips though sending your assembled product off to be certified is whole load more investment, so most will be using that cable anyway cause it means they get to use the logo still.

You can tell from firstly on the box, where it's classic cheapo tactic having the UL Listed line sit after the cable description so it means it's not an illegal claim about the whole product, which having it sit as a separate bullet point would be, yet they can still fool people into believing whole product has been certified. Secondly in the manual, the only standards they say the fan conforms to are general Chinese domestic electrical appliance standards and if the whole fan was UL Listed then you would very much expect them to be including that in this section!

There's no reason to say they're junk, and my experience with cheap MiC stuff is it normally just stops working rather than is any actual risk, though yep i agree worth keeping an eye on as always.

And not being rude to the company either, as they're welcome to sell whatever they please, but their email response to you says it all too!!

Dealing with these companies is always hilarious, as I mean, do they expect anyone to believe they've even got an R&D dept doing product upgrade work atm??!

Are they currently trying to revolutionise brushless motor technology? Are they looking into making seamless, one-piece castings of fan blades??! I very much think not lol!

What this email basically translates as is; better parts cost too much at the moment and when we can source them cheaper we will do!!!
 
I asked them directly and they said the fan is listed, but I think they’re lying. Can you take a photo of the UL sticker? Should be able to look up the standard number that they’re referencing. It’ll either reference a fan spec or a cord spec.
 
Yeah Rik I mention in my post on 03-27-2021, 02:09 PM, there is nothing on the fan but the cord stamping. Besides that, just the box UL logo. I’m in agreement this doesn’t appear to be listed. I guess we’ll see if they even answer my Email.
 
You may have missed my post on 03-27-2021, 02:09 PM. I agree with Rik there and explain how there are no labels or markings. I’ve even emailed to company asking for UL verification, which I doubt they have.

I’m aware of the long drawn out procedure to obtain actual UL listing. Just went through it with a heating mat with ac infinity. I was sent an old version that did not have the UL mark on it like the photo in the ad. They reimbursed me and are sending me the new model when back in stock.

Ah, good to hear they reimbursed you then dude, and hopefully they'll prove me wrong in future and come back to market with some game-changing clip-on!
 
Sorry if it seems like I’ve been pestering you MrPNW, I definitely don’t mean to. I guess I’m a bit overkill on these kinds of things, especially when I catch companies outright lying. I only want to make sure I’m clear for everyone reading that these fans might not be as safe as they appear. But yeah, you and I seem to agree and have a common understanding.
 
Not at all Rik, nobody needs a tent or house fire due to falsely advertised equipment. The moment I noticed the cable didn’t have one of those do not remove stickers wrapped around it I had my doubts.
