I use this with a dryer duct from dollar general for like 4 bucks [link]
Super cheap lightweight intake to get proper circ , quiet just gets job done for a smaller area
I see infinity and Vivosun have some 30 dollar options . [link]
Like this . I don’t wanna cheap out tho . This is jus the first thing to pop up what u think .
An exhaust fan at home Depot/Amazon is 30 bucks. [link]
This isn't too expensive, not sure the budget
You'd still need a carbon filter if you wanna control smell
I bought 2 of these and some 4” ducting from amazon and probably paid about $50.
Here is a link if you would like to check them out.
My shop is in my basement. I don't have a window so I installed an exhaust fan that is hung over my soldering station. It uses a standard 4" dryer vent hose.
I'm sure you can find something similar like a bathroom exhaust fan.
I didn't want the fumes accumulating in my basement since that's where the heat/ac unit is located.
Put a board in the window. Drill a 4 inch hole in it. Insert a laundry vent with the closing slats. Attached vent to 4inch dryer tube, or some other guy recommended a portable AC vent tube. Then attach the end to a 4 inch in-line fan.
Plug the fan in for ventilation.
You can up it to 6inch diameters if you're smoking at an industrial level.

I wonder... If this: VIVOSUN 195 CFM 4" Inch Inline Ventilation Duct Fan [link]
Limited-time deal: Inkbird ITC-308 Temperature Controller 1100W Heating Cooling Thermostat for Greenhouse Incubator [link]
Would work? With some aluminum tape and ducting to seperate the fan from the smoker.

VIVOSUN 4 Inch Air Carbon Filter Smellines Control with Australia Virgin Charcoal for Inline Duct Fan, Grow Tent, Pre-filter Included, Reversible Flange 4" x 14" [link]
For my grow tent's air intake I use an inline vent fan similar to this one, which I cover with this style of HEPA filter. It seems to work well.
Bathroom Exhaust Fan might be a potential solution here. You can get them from 50 to 200 cfm, giving you plenty of options, and they are generally pretty quiet. They look something like this: https://content.interlinebrands.com/product/Image/Detail/10129/310450156_usn.jpg
You should be able to remove the plastic cover, and mount it to your filter retaining box behind your machine.
If you want something simple, you could go for something like an inline ventilation blower, which looks something like this: https://www.amazon.com/VIVOSUN-Inch-Inline-Ventilation-Blower/dp/B01M7S46YZ/
Mount a 4" flange to your filter box ( https://www.amazon.com/POWERTEC-70126-Inlet-Flange-4-Inch/dp/B00DJBXP5E/ ), run a hose from that to the vent fan, then run a hose to the outside. I use something like this for my Laser Cutter, and it works good for that, so I imagine it would work well for a spray booth.
That said, the bilge blower you listed is almost double the CFM, so it might be a better solution, provided the noise it makes isn't a problem.
Does the laser you're looking into getting have an enclosure to ventilate from? If so, this is easy. If not, you should consider buying or building one.
I'm in a similar situation - I just got a k40 and I'm in an apartment. I have sliding windows, although mine open vertically.
I got a 2'x2' slab of Owens-Corning Foamular from a big-box hardware store - it's bright lavender so you can't miss it. It's very lightweight, very insulating, and it's both rigid and easy to cut. I also got a dryer vent hookup with a backflow-prevention flap. My cutter came with an aluminum flex tube, if yours did not you should get one. Plastic is unsafe for this. You'll probably want a couple metal hose clamps that match your diameter too.
I also ordered a relatively powerful and quiet centrifugal axial fan - this is the one I bought as my tubing is 4" in diameter, and it has a stand built-in. I previously bought a slightly cheaper, wimpier one and refunded it because it didn't produce enough airflow or suction. This one has enough power to keep my whole machine and my ducting under vacuum, so smoke can't possibly leak out into my apartment.
Using a utility knife and a straightedge, cuta slab of foamular a couple inches wider than the diameter of your vent hookup and long enough to fit into your window. If your window gap is too long for the slab of foam you bought, you can slice a couple slabs and glue them together. Next, use the hookup to mark out a circle on the foamular. You'll hook up the fan directly to the vent hookup later, so make sure that it's somewhere that your fan can either rest on the windowsill or be supported by some kind of shim or platform. You can use a utility knife to do this, or if you have a hole saw that will make it quick. Test fit the vent hookup and then glue it in - hotglue works, or use a strong, leakproof tape. Position the fan against the dryer hookup so that it flows through the hookup (blowing out the window) and tape it in place, and support it with cardboard or plywood shims if necessary so the vent hookup isn't supporting the weight of the fan. Then, just run the flex tube from the inlet of the fan to the exhaust port in your enclosure and clamp both ends in place. Then all you need to do is place the foam slab (with fan and vent attached) into the window and shut the window to hold it in place.
I can send photos of my setup if that would help, let me know.
So, there’s a cheap way to do this, and an expensive but cool way to do this considering your setup.. love the 3090 miniATX by the way, it’s just so min/max.
Cheap and kinda janky- something like this: VIVOSUN 4 Inch 195 CFM Inline Duct Ventilation Fan Vent Blower for Grow Tent [link]
It’s janky because you need to run it off a 120v supply - but, it will get air where you need it, and it’s quiet. 200cfm is more than enough.
Cooler, and more expensive (if you go all copper - which you should...) but looks like a lot of fun is something like this build LTT did (2:30ish) [link]
Copper rods aren’t too expensive, something like this might do the trick: (10pcs 1.2X3.2X500mm Flat Silver Electrode Low Temperature Phosphor Copper Welding Rods HL201 Self-fluxing Alloy Soldering Brazing By Keaiduoa [link])
But I could see this getting futsy really quick if you’re not aligned really well. So you may want to go with a much larger single heat sink to cover the vram and go with bigger flatter copper rods - all about the surface area. Anyway, the copper should xfer heat well down the rods to ostensibly another heat sink where you can put a fan.
Man, that looks like a lot of fun actually.
Or you could bite the bullet and spend the 1kish to water cool the thing like I ended up doing.
Good luck - let me know what you end up doing!
I've decided to just build my own pad.
I'm going to open up the pad under the grills, silicone around for a seal and hook up one of these bad boys to it.
If that doesn't do it, I'm going to make an arm which seals to the exhaust in the back that's hooked up to another of those fans (but backwards for suction).
I got a 6" which was an overkill
VIVOSUN 4 inch Inline Duct Fan 100 CFM, HVAC Exhaust Intake Fan, Low Noise & Extra Long 5.5' Grounded Power Cord [link]
Good for a 4x4 to me
Fan for your exhaust, this one can be powerful but its 32 bucks, and there will be a link for the controller which lets you dial the speed as you want.
duct hose and clamps 9.99
heres pics of when i built mine.
so basically , all you do, is flip a plastic tub on its side, cut a round hole for your fan, slide it in , secure it with dect tape, put a airfilter you can get at any hardware store over the front adhre it again with duct tape, then plug the fan into the controller, the duct hose into the exhaust of the fan and bingo. and you can run a longer hose iof needed right out the window,
i put a T piece on my basements dryer vent and i just blwo it out the window, super easy peasy.
My studio is in my basement with no window. I searched online for an exhaust fan that moves a lot of air and could be connected to a 4" dryer style hose. I installed a dryer vent to the outside of my home and connected it to the 4" hose. I mounted the exhaust fan on a vertical bar so I can raise and lower it.
I have it plugged into the same power strip as my soldering iron. When the iron is on, the fan is running.
I did look at bathroom exhaust fans and kitchen over the range exhaust fans. They were expensive and didn't move as much air.
I went with;
Its not too noisy and easy to install.
I really can't smell much of anything, amazingly. My wife has the nose of a bloodhound and hasn't noticed anything when in the next room, so that is also a good sign.
I used the adaptor to run a 4" duct to a fan (https://www.amazon.com/gp/product/B01M7S46YZ/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&psc=1), to another 4" duct to this filter: https://www.amazon.com/gp/product/B01DXYMBU6/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
I keep the fan running when printing. I've got a small Levoit purifier but really only run it when curing (even that really doesn't have much of a smell - the alcohol has the strongest odor of anything I'm using).
This would probably be plenty. Just need to buy the right size ducting. But look around on Amazon they probably sell one that comes with the ducting.
VIVOSUN 195 CFM 4" Inch Inline Ventilation Duct Fan [link]
Is this the one you’re talking about?
I have a 2x2 tent and a Can Fan S-400, which was what my hydro shop recommended when I was getting started. There are no doubt cheaper 4" fans on Amazon, but it seems very well made and has a 5 year warranty. I also have a Vivosun 4" fan, which I run freestanding with a carbon filter attached to scrub the air during harvest. It works, and isn't especially noisy, but feels very cheaply made.
I've heard people say that a 6" fan turned way down can quietly move a lot of air, but haven't tried it, and a 6" fan on full speed could suck in the tent walls too much or even tear them. (I get pretty strong negative pressure with my 4" fan on full!)
I haven't used any fans with an integrated speed controller, but the external fan speed controllers that actually reduce voltage are vastly superior to the cheap ones that just rapidly flip power on and off -- depending on the fan motor type, the latter can damage the motor or produce loud buzzing as you slow it down past a certain point. When I tried one with mine, anything below 80% or so started buzzing. The better controllers cost a bit more ($70 vs. $15), but since it's actual industrial equipment it should have good resale value.
My tent is in my home office and I don't find the noise problematic, if that helps.
It depends on the fan really. Different models are more effective at pushing or pulling. Read the details of the fan models. I picked up this one ( [link]) off Amazon and have it pulling. I put it as close to the exit vent as possible and it does a very good job. I'd say when in doubt set it up for pulling at the end of the line.
4" intake fan. I have to saw off the top p to fit.
4" carbon filter. Filters
Arizer Extreme Q Vaporizer is the cap I have for this setup.
I also have a small smoke pipe that I smoke the vap weed from. Which smells like burnt garbage but gets the job done.
Took two weeks before my wife caught me smoking. She's totally okay with it now and I dont feel like some kind of teenage sneaking around. Its life changing.
So for anyone wondering if you live in the US you can get a 4 inch fan and filter for about $30 each from Amazon. They work great for dealing with the smell and they draw a ton of air which takes care of circulation. Depending on your final setup you might have to worry about wind burn but that can be managed with a speed control if its issue.
fan $29 - [link]
filter $31 - [link]
A carbon filter is made out of activated carbon. In my opinion they are only good for capturing dilute fumes, not for when the stuff going through it is mostly fumes. And it won't catch 100% of the fumes on the first pass, so it will have to keep filtering the air over hours to get them all. Not ideal for your living space.
Yes the wind is an issue. If the wind is stronger than the fan pushing the air, then you'll get it pushed back. It happened to me a couple times even with my fan on max. I printed a little 'spout' for the end of my hose, so the exhaust would be directed downward (hence the wind blowing directly at my house would not go into the hose hole). You've probably seen vents out of houses that look like an upside down 'U', it's like that.
In theory you can always get a more powerful fan/blower. I bought that this cheap ass one off amazon, it's barely strong enough for me (keep in mind I have about 10 ft of hosing too). It's a piece of crap, the smell was leaking through the seam of the plastic housing of it, so I had to disassemble it, and wrap teflon tape around the seam on the inner lip, then put it together, and wrap duct tape around the whole seam making sure it was flat with no ridges. That solved it.
Like I said the room still smells a bit though, but I can live with it. If it was my living room I could not live with that. I like my brain cells.... ish.
FYI I also made a DIY fume hood out of a cardboard box lined with foil to do the post processing in, so the isopropyl alcohol / resin smells get vented.I then have a bottom half of a carboard box inside that box that I use for pouring the resin back into the bottle, so if there is a spill I can just throw out that inner box (after curing in the sun to render the plastic inert). I haven't had a spill yet, but you never know. Don't take chances; this liquid plastic is nasty as hell, it is pure poison for planet earth.
I don't know how handy you are / your budget, but building a proper box for it (with seams sealed with silicone and walls sealed with lacquer to prevent fume seeping) and getting a strong blower will save your brain cells methinks. Better to buy a more powerful fan than an under-powered one. I might get a more powerful one soon, and rebuild my box. I build it fast just to get printing and its served me well for little over a year, but the tape holding the cardboard together is coming undone lol.
I use this controller, just because I heat up the box and I don't want to waste electricity heating it up just to get it sucked out. If the wind is strong though I plug the blower directly into the wall because it gets the most power that way (there is an audible difference of the blower).
No need for anything shady. It's all on Amazon.
I use one of these fans attached to the back. Air pulls in from the vents on the bottom.
VIVOSUN 4 Inch 195 CFM Inline Duct Ventilation Fan Vent Blower for Grow Tent
I push the air through one of these filters.
VIVOSUN 4 Inch Air Carbon Filter
If I had the option, I'd vent it outside, but there isn't a window near my printer, and I don't want to cut a hole in my house.
Sorry it should be inline fan
Here is one
bought this with some duct and a carbon filter
no, but this will
it's also quiet and will pull through a carbon filter when you need to, that other little one isn't much good
So really this should do the trick?
