Hmmm...Brown with pink designated as switch

And the other brown with red and orange allocated to potentiometer




Looks to me like the red connects to the center

That’s just it, that’s what has me scratching my head...

See the pin where I connected the brown and pink, that’s the only brown there, so where is this other brown ? That’s where I’m confused

The odd man out in that cluster of five wires would be the 'other' brown wire, probably dark brown, imo

The on switch should be independent of the speed control so if you don't have the brown and pink connected it most likely won't turn on. I would just add a 10k potentiometer to the brown, red and orange wires so you have variable speed rather than just high and low.






Another thing is really technically I am connecting the brown and pink here where I circled with yellow high lighter and the orange and Red also come from here



Im not sure where the connector which I highlighted I green is, there is only one connector with 5 pins on it and it’s labeled CN4, I’m assuming this is where I should have made the connection but instead I made the connection at the 7 pin conector

From what I see here

pin 1= brown \
Pin 2= red.      Potentiometer
Pin 3=orange /
Pin 4=brown \
                    Switch
Pin 5=pink    /

Is this correct ?

So leaving the brown and pink connected at the seven pin connector, the yellow high lighter
I went to the 5 pin connector CN4 and when I connect pin 1 brown to pin 2 red it turns off
And when I connect pin 2 red with pin 3 orange nothin happens (yet if I connect orange and red at the 7 pin connector the fans go full speed)

Thanks, you say just get the requirements I want but Im not even sure about what requirements I even need want or can have.




You need:
  • 36V
  • Enough current capability with some headroom as a safety margin; let's say anything beyond 6 or 7A.

Those are the requirements. Now pick a unit. I'd go for one that's reasonably cheap and won't take ages to arrive.




First of all thank you and kwyjibo your help! I wouldn’t have been able to do it without you!

Is there anything I can do for you?

I almost have this all the way up and running but I need some opinions.

So... technically I am connecting the brown and pink here where I circled with yellow high lighter and the orange and Red also come from here

Badass man!

So the FFU works just like a laminar flow cabinet?

Yes it should, except I’m still missing one more up grade.

I have to add a potentiometer to make the fans variable speed

You might let us tie up our boats at your dock in Key West if we ever get down that way some winter.

Only thing is I am not as far south as the keys...

Unfortunately

However I am close enough to be able to meet you down there.

10/17/19 Update!



Before this the fans did not blow hard enough because the pre-filters I installed added too much StaticPressure.

Now the FFU is up n running with variable speed and definitely blowing hard enough!!!

The little aluminum cylinder on the back of the unit inside that open box is the potentiometer nob it’s around half speed, maybe a tan higher.

I took the entire filter off and found a good spot to drill the hole for the potentiometer Nob to slide through. I purposely put it so that it would come out of the unit meanwhile still inside one of the boxes on the back to protect it.

I have yet to use it for a session but I did run it for a good 10-15 min and it’s a dream come true!
