Having just modified my Endless Breeze fan with a PWM speed controller, I noticed something strange……

Before I started, when I looked at the fan from the front, with the support feet toes image facing me, the on off switch on the right and the fan support frame at the back…..my fans blown air is going the other way. ie the opposite to what it shows on the box.

Can anyone with an Endless Breeze fan confirm this is the way their fan runs.

Ps….the polarity on the cigarette lighter plug is correct (12v tip)

Cheers…..Strange to design feet that have pictures of toes on one end and heals on the other and then position them back to front for the fan to blow towards you.

Obviously the blade is designed to rotate that way, because of the shape of the blades.
 
Mine blows towards me when the toes are pointing at me. This seems logical as it is "facing" me. If it blew the other way it would be blowing out of its bottom. :)

My thoughts exactly…..

When I added the PWM variable controller, I switched the output polarity to the fan, so it was blowing the other way, but it doesn’t feel as strong.

The blade does show an arrow in both directions for rotation.

I’ll check later with an anemometer.
 
I’ve got a Boundless Breeze fan being delivered tomorrow……I’ll do a comparison at some point too.

May I ask a silly question, why are you adding the PWM controller?

There’s no such thing as a silly question….

It’s not PWM as your thinking as in solar, it’s a variable speed motor controller, so the fan speed can be infinitely controlled, rather than being low, medium or high.

Oh…..and I already had the controller from another project 😉

I was vaguely aware it was a motor speed controller, but wondered what the need / solution was? Is the standard speed control not granular/precise enough? Can the new controller be linked to a remote control facility? Something else?

Ok…well it gives a wider working voltage range all round and it’s more efficient than the big resistors used in the original mechanical switch, that just burns power so there is less to go to the fan motor to slow it down for the lower speeds and it’s now variably controlled.

The new controller just replaces the mechanical switch and a potentiometer replacing the switch varies the speed.

Oh and also because I could 👍🏻

I will be interested to see how you get on with the new controller. Ideally some before and after current measurements! But I took mine apart recently for cleaning, which I've done before, but this time I noticed the coiled resister wires which are used for the two lower speeds. This is a very inefficient way of doing things and will waste power. A PWM controller should be much better.

I didn’t check the current draw before hand but used a bench power supply at 12v afterwards.

I’ll check the draw at various points when I get time.

I still can’t understand why it’s assembled the way it is, but if I run it back to front with reversed polarity from the PWM output it definitely moves less air, its a few MPH less too, according to the anemomete. 😢

PWM controller I used (LINK)

I mounted the controller vertically bellow the control knob hole.
The only cable I had to lengthen was the negative had to be extended from the bottom corner to the top corner and re-routed one cable from the fan to the top corner then I changed the spade connectors to ferrules.

Well, the 12v Boundless Breeze fan has been delivered this morning…….first impression is it looks and feels the same sort of quality as the Endless Breeze.

I‘ll update when I have plugged it in and tested it. 👍🏼

Is it made by Dometic?
 
Slightly (only slightly) noisier, slightly higher current draw….but substantially cheaper and moves more air than the Endless Breeze (if you can get one).

Ordered from Jeff‘s UK shop below and delivered from America in about 5 days
👍🏼




Amazon product ASIN B06Y196VR8
and a I found a ready made review…..



So far so good….

So the endless breeze is quieter, uses less power, has a better handle, better sturdier legs, is better made, but is a lot more expensive.
You get what you pay for, we’ve had our endless breeze 15 years now still perfect.

I have both and the differences are really very very minimal, I don’t think your comments are very useful to people who can’t get an Endless Breeze.

it was posted as an alternative for those that can’t get hold of the Endless Breeze.

Oh and you forgot to mention the Boundless Breeze is slightly noisier and draws slightly more current because it moves more air 😉

Boundless Breeze looks a good buy since EB are so difficult and expensive to source 👍
 
But presumably if fitted with a speed controller of the sort you mentioned at the start it could be turned down to a slower and quieter speed? Assuming the motor is suitable of course.

I’m going to have a look inside the case to see if there is enough space to fit a controller in, as I’m guessing the speed control mechanism will be the same crude affair as I replaced in the Endless Breeze.

It might be a tight squeeze, if at all possible, as there are no corners for it to live in.

I’ll post my findings when I’ve had time to open it up 👍🏼

Just modified my Boundess Breeze (Amazon from America) as suggest by XxAnthxX above in August
Works great , a little noisy, but impossible to get the gubbines in the round case
