Quietest Inline Air Duct ?

[JBloomers123]

Hello,

I need to replace my years old inline air duct fan- its getting a little clanky / noisy. The brand was hydrofarm and it worked well. I cannot find the same specific model so If you have any recs I'm all ears.

Thank you,

AC infinity

I have the ac infinity T6, it's very quiet but kinda pricey. For the price point I expected more features but it lacks a feature I would like. Variable speed based on temp is lacking. It either turns on at a selected speed for a selected temp or it's off, no in between. Look up its features. It's like $150 for the fan

What would you say is the upside to that vs the T6?
Because it would save 50 bucks? The controller has a speed option 1-10, just not a temp program that coincides with the variable speed.

Mostly just that I can keep it at a constant speed and it won’t shut off so I can maintain negative air pressure in my grow space so no odor escapes when the in-laws come over. Steeping smell of cannabis would be very naughty in their book. Lol.

The T6 does that too haha, I cant help but feel there has been a miscommunication.
What I want it to do is be able to self regulate. I run it all day at 30% but I would like the temperature controls to take over if the temps get to the 80's, then increase speed until it has cleared the heat back to 75 range.

 

[JWM2]

Yeah but why would I pay extra for that when I would be using it like any other inline fan? I might as well save the $50-60 and run a separate controller that can control other things also at the same time. The inkbird controllers are $60 for both temp and humidity and can control multiple devices such as heater, humidifier, dehumidifier and AC all in one unit.

Then if the inline fan breaks I can just replace it and save myself money. It comes with the same two or three year warranty.

I don’t think you can buy a fan that does that on its own without controllers and such..

That's what I was gonna say! Hell, another 50 bones to put towards nutes or your next lights!

Not about the controller though, im in the dark still about all the systems out there.

Regardless of temps you want good amount of air blasting through. For negative pressure and also plants like that good c02 shit

c02 is for noob growers, i give my girls nothing but the most pure oxygen money can buy

Oxygen is good too! Roots like it and it’s nice to not pass out in the grow room lol

Exactly. What they need is just a minimum fan setting so on auto mode it will default to the set lowest setting and only increase when the temp rises out of the preset range. Then it would be fine. The fact that it turns off completely is a deal breaker for someone like me that has to have odor control at least a couple times a year when relatives stop over. The rest of the year I’d be ok but for a few days I can’t have any odor creeping out of the grow space. So for those days that ac infinity fannjust wouldn’t work unless I put it on manual control and then it’s rather pointless. By running desperate controllers I can completely automate my environment controls without being handcuffed.

Dang, I didn't know i was going to blow up the discussion over seeking a new in line duct fan - appreciate the feedback and will take a look at the recs. All i want is a quiet fan that will run constantly @ 20-30% to exhaust the odors of our trade. i have other controllers in play to regulate temp and humidity. thanks again!

That looks like a keeper - my room is fairly small - even the 4inch would prob work. no issues connecting charcoal filter? on my current fan I'm replacing it was a bit of a hack job making the connection - Hydrofarm hadn't thought that one through. Thankful for duct tape.

This is what makes discussion great. Now you got options and the pros and cons of each :-)
