SOG Fan Broke- Dealers Mark Up is Shocking

[Abacist]

Without seeming a total dummy

Could you not get a 12v fan of the required spec and fit it into a bit of tube the correct od.

Or even cut the old fan out of the tube and fit a new fan

Sounds simple doesn’t it!

You try it!

 

[Gromett]

I just did a quick rough back of the fag packet calc on how much I could make an alternative for that would be commercially viable for me to make by hand.
I could do a cheap one for myself. But for one that would be sellable as a product I couldn't beat the price of the original without working my nuts off for very little money.

 

[Flairy]

You could always call in at SOG on the. Mosel there’s a stellplatz they own next door.

 

[cyberyacht]

Just get a very strong air freshener.

Well you did want suggestions as to what new hobby to do in your workshop!

I put a computer fan in the toilet skylight, it takes away smells but also dries the room very quickly after a shower

 

[Lenny HB]

Looks like it is a MICRONEL D341T-012GK-2 motor?

That one is 32mm dia SOG fan is 20mm.

 

[Deepingvet]

The very thin electric wiring has come off mine and nearly impossible to reconnect..we now just put up with the smell..

 

[Gromett]

I don't think you are correct. The image shows this code
D341T-012G

Which could only be
D341T-012GK-2

The 2xmm fans from Micronel would have a code starting with D2 Not D3

 

[Terry]

I made my own SOG years ago and was determined it was not going to cost me a penny- basically from bits I already had I posted on here. Sorry no link but if anyone finds my original It would be a very early post from 2007/8
Just done a Google search for 12v Inline fan - loads from £12 to £25

It is a lot but the roof ones are a lot different to the toilet door ones, no idea why it costs so much to be honest as its just a small fan in a plastic housing.

The toilet cassette door ones are more expensive than that.

 

[EuroTrotters]

Can you not just buy some of that undertakers cream they rub just under the nose ? Bit like Vicks?

 

[Millcourt]

That's my thinking as ours isn't sucking as well as it used to do I'm going to have to investigate when we get home.

Really sorry to hear yours isn’t sucking as well as it used to. Must be an age thing!

I just followed your link, just had another look, boths links are for a 36mm fan.

 

[Steve and Denise]

No it’s not
The outlet is 20mm

Either I didn't explain myself very well or you misread what I meant

In post #11 there is a picture with a partial part number.

D341T-012G is what I can read.
This only matches the full part number
D341T-012GK-2

Which is a 34mm part.

If it was a 20/22mm fan then the part number would start with D2 not D3.

If you go to their website and use this filter https://www.micronel.com/en/productfinder/?sort=&product_line[]=Tube Fan&pressure=0&freeflow=0&size_square[]=&voltage[]=&electrical_power=&brushless_driver=&for_breathing=&o2_resistance=&acceleration=

You will see all the Micronel Tube fans.

Look at the size vs the part number and you will see that D24 is 24mm D30 is 30mm and D34 is 34mm etc etc.

Hope that clears it up?

The outlet is a different thing from the fan diameter.

Yup, that will shift the fart/poop smells nicely

Notice they don't specify the static pressure or freeflow?

Also will it work ok in a humid environment with possibly corrosive/acidic gases?

At that price who cares? Thetfords own version fits under the cassette and uses a standard computer fan.

My point was that if it doesn't specify the amount of air it can push and what the static pressure is. I very much doubt those figures are going to impress. I suspect this fan would not work for the purpose.

A computer fan is much larger so can pull the air.

The "computer" fan Thetford use is around 40mm square and moves very little air. But, again, at the price it's worth buying one to test.

 

[Silver-Fox]

Try finding a fan of the same spec/size/shape etc. I can't.
It would need some 3D printing doing to design and develop a new shroud/mount/adapter and it still has to fit in that limited space.

Is there one on general sale that is a bit smaller or same od as the genuine one?

If so you could make a holder out of modelling plastic or similar.

Or even fibreglass.

I don’t know enough about 3d printers to comment.

Looks like an 60-80mm fan to me.

But size isn't everything. Although swept area makes a big difference you can make up for smaller swept area by increasing rpm it is not linear though.

That tiny little fan you originally linked is unlikely to be able to do the job looking at it. Even cheap computer fans give the specs usually in cfm even if they skip the static pressure.

I have not been able to find one that has suitable specs within those dimensions. I think this may be why SOG chose this one.

Unfortunately I don’t have a sog so can’t “investigate” it further

What about increasing the size of the tube holding the fan and reducing it back down onto the original pipe?

Would that work?

 

[Terry]

In my DIY efforts I tried 2ins computer fan then 2x2 ins then a 3 and 4ins. 2 ins were not powerful enough. Both others worked good

 

[Gromett]

Not likely as it would increase the resistance that the fan was expecting reducing it's performance.
A fan blade is designed to move air through a space equal to it's diameter usually.

It is has been a VERY long time since I did this at college so my memory of the principles and theory are vague at best.
But you do not want to restrict the flow.

 

[WASPES]

This is ours as it goes through the roof so slightly different to the floor ones. Still a rip off though as the price on the picture is plus postage but it's the cheapest in the uk
