The purpose of those lines is to create airflow to prevent carbon monoxide poisoning. They function passively, so you should uncap them, for safety sake (or at least make sure a COO monitor is installed... fuck, I don't have one installed....). Notice how one inlet is (or was, or should be) at eye level, and the other is near the floor? That is to make use of when heat rises, the air near the inlet of one will rise out, and the cold air near the bottom of the other will sink, starting a circulating flow. Yes, this chills the basement, but, if it's unfinished that's OK.


a 100k but furnace may use rpoportionatly more air for combustion, but its in a controled space and a very efficient combustion, while the 54K burner will disperse the COO along the heat current it creates meaning you need to remove much much more air to gather all the gasses you should, than with just a sealed vented furnace. Also, there is a difference between inline duct booster fans, which aid in airflow, but lack dynamic pressure, and turbine fans which are both consistant rate and high dynaic pressure (meaning it would be able to pull air from a further distance with less drop in CFM)

These http://www.amazon.com/LEDwholesalers-GYO2402-6-Inch-Hydroponic-Booster/dp/B003YFADW8 won't work,

you'll need this http://www.amazon.com/Active-Air-720-Inline-8-Inch/dp/B002JQ4K1I

or for a quieter operation with better dynamic pressure, this http://www.amazon.com/gp/product/B001I4DHJI/ref=pd_lpo_sbs_dp_ss_2?pf_rd_p=1944687782&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B004C2IWIE&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1V2RCEEAMG31CYMSKC7B

I am not trying to be alarmist, but I know the math off the top of my head, because I've worked with it SOOOoo many times, and as they are for safety, I urge you to heed my warning.

Well, my grow is a LOT larger than a closet but the principal is the same.

I have a bigass inline fan that sucks the air from inside the room out into my attic and the carbon filter is attached in the attic.

So basically I am sucking the smell out of the room, thru the carbon filter and out into the attic.

This creates a negative pressure in the room so the smell actually gets sucked BACK INTO the room. You can stand at the door to my grow and not smell a thing.

Your setup should be similar, just with much smaller parts

You could do the bath fan idea but with a much more powerful fan. Something like this that vents from the top floor to the outside, in combination with some opened windows, would probably help quite a bit -- as long as there is cool (and not too humid for your tastes) night time air available, and you don't mind leaving windows open for hours. But it's kind of a hack, and if you could tweak your existing ducts to work better, that would be more ideal and wouldn't require messing with windows and whatnot every night.

i'm looking at this one:

and:

http://www.amazon.com/Active-Air-720-Inline-8-Inch/dp/B002JQ4K1I/

would these be considered good quality? or do i need to spend roughly twice as much?

thanks for the info.

I bought one of these for exhaust of my 7 GPU rig and I highly recommend it. Active Air 720 CFM Inline Fan, 8-Inch https://www.amazon.com/dp/B002JQ4K1I/ref=cm_sw_r_cp_apip_Nx8lUuqP8GAKB It’s been running about 6 weeks now and does a great job of pulling the hot air out of my storage room and some “cooler” air in through my louvered door. I tried a small room A/C but this is a much better solution - it vents up to my attic and out my ridge vent. I built an exhaust manifold with 3”x12” ductwork with (14) 2” diameter holes in it which gets the exhaust closer to the output of each gpu in the rig. Will post some pics.

You need an activated charcoal filter. I have one for my shop that I use for VOC (fumes).

  • Air Carbon Filter
  • 8" inline Fan. Assume a 20x20x8' room, 720 CFM is a air change over every ~4.5 minutes.
  • Ducting

    Put the charcoal filter where everyone is. Put the fan as far away as you can with the ducting. Dirty air gets pulled to the back of the room/building blown through the duct out the charcoal filter. You set up a natural breeze.


    Warning: Buying any of these products will make Amazon think you are grower of ... other things.
