I was thinking about going with the S&P TD-100 4" fan, and then using a splitter and having that fan both cool the light and the carbon scrubber.

Any thoughts on this matter?

Wont work, I tried it. The open end that doesnt go to the scrubber allows the fan to breathe. In other words, it doesnt create enough pressure in the ducting to pull on the scrubber since the air has an easier route through the tube.

Hope this helps.

Think about it like this. If your straw has a hole in it, you cant suck fluid through it right? Its because the hole allows the vacuum to escape.
Same applies to the ducting between the fan and the filter. Filter creates resistance, so the fan creates pressure between the fan and the filter. Add another route for the air to move, and the fan doesnt need to create pressure to pull air throught the filer, the vacuum is broken from the open end of the cooltube.

I have a cooltube and against other readers suggestions I run mine like this:

Filter>Ducting>intake of fan>ducting on exhaust side of fan>cooltube>ducting>exhast vent.

They say you shouldnt push air through the cooltube, however I dont have any issues doing it. And I believe the heat from the bulb, sucking through the fan could create an added heat in the fan on a long term basis. Im straight on the extra heat in my fan.

Thats how I run everything on 1 fan. Hope that helps...

Thanks for the response.

I am now using a td100x (in a 24x36x60 tent) right now like this
scrubber>light>fan>out

it is keeping daytime temps at 82º. I am stoked.

Just bought one

hoping to add a carbon sack to the end.... like a pillow over the exhaust..

TD100X for $88 shipped .... not bad. I hope it pulls good on my grow box

Yo glad I found this thread before I purchased my stuff.

I planned to grow in a DR80, just 2 plants w/ 250W bulbs and a air cooled reflector. I'm looking for the quietest setup possible; Would the TD-150 have enough power to suck all the air through the carbon filter?

I also had my eye on the Panasonic Whisperline FV-20NLF1

Does anyone know which is more quiet, or overall would be better for my setup?

Hi there,

I got a TD 350 S&P fan, wich is not referenced in this topic. The specifications are not on the official website, I only know it is a 350m^3/h.
What would the best carbon scrubber for this fan (I got a cooltube with a 70 cm duct on it).

Thanks !

Edit : I have finally chosen this one :

Seems to be ok.

I've just ordered the TD200 Silent series which are being released in the US tomorrow. $275 w/ shipping, but runs 75% quieter than the equivelent Vortex fan. Combo'ing this with a Mountain Air filter and should be set!

Stoked these fans are available now, they may be a bit more expensive, but stealth is key for me and this should do the trick!

Yoyo yo.......Im back y'all. Hope everyone is well. Been an exceptionally long time.
