Always make sense you know what your doing brother

Lol, right there with ya.
Just looked at how you have it mounted. The bolts will transfer vibration. Something like this Is one option. Bolt to angle bracket on joist then to board or metal at four points and mount motor to board/metal. That fan will produce a fair amount of noise due to the rpm’s and type of blade it uses so moving the return grille as far away from motor the better. I wouldn’t think you would hear air noise from that grille, looks big enough, but if you are, then installing a second would stop it. Using air conditioner flex duct for the outlet run would reduce a lot of vibration noise being transfered into the rigid, especially if it touches something else. Maybe use a 6"X8" transition at fan to increase duct to 8" to reduce velocity and offset flex’s resistance over a 20’ run.
Is it exhausting outside? What is feeding the supply grilles on the left lower side in picture? How are you making up air to room that is being exhausted?

Doesn’t look like you’ve had any time for the smoker.
Mrs. C got effed up as a bucket of worms today. So the veggies we were supposed to eat never got cooked. Made an awesome sandwich though. She deserves it though, just for putting up with me. Lmao

I wonder if sound dampening liner would work typically used in car audio applications comes in rolls on Amazon

Thanks @Bunger64 !

Thanks for the info! It has the 2 filtered air pathways. I can’t remember the size right now but I think they are 4x8. No fans blowing in the exhaust is doing that work right now l. There is enough negative pressure to suck the door shut before I added stripping to it. It does not exhaust outside but I have thought about it. Not sure I wanna commit to cutting a hole yet.
Those vibration isolators are BA!
Thanks for sharing! I haven’t gotten around to smoking anything lately, now I want to!
I DID look into that. Would take a lot though…

It would increase air flow in addition to velocity in output side.
If you could then reduce fan speed noise would be reduced
Restrictions require fan to run faster, as in on max, to provide desired cfm. Faster = louder.
Using a piece of flex duct between motor and rigid would reduce vibration to rigid duct. Velocity would stay same though.
Oversizing fan capacity by having larger fan or multiple fans and then reducing the speed to have same cfm with reduced noise or sound proofed fan enclosure.
The door being sucked shut suggests your transfer grilles (in wall) total surface area is too small. Rule of thumb is 1 square inch of grille face for each 2 cfm. CFM/350X144 for total square inch of grille needed. If fan is 350 CFM then 350/350= 1 sqft X 144 = 144 sq inch of grille required. If the 2 you have are 4X8" then it’s 64 sq inch., roughly less than half of what’s needed for 350 CFM. Oversizing here would improve efficiency and reduce air noise through grille, so 5 of the 4X8 grilles would be 160 sq inch. The grilles can be bigger and fewer to get to 160 sq" if desired. Whatever is most aesthetically acceptable.
Once vibration is controlled and air flow is unrestricted it’s going to be a trade off between acceptable noise level vs cost.
ACI list the noise rating of their cloudline A6 at 34 dBA at full speed moving 352 cfm assuming that’s what you have.
It’s what my 2X4 tent has. I have all the openings at bottom open so I can run the fan as slow as possible to maintain climate and I still have to run it on 7 max with lung room at 73 to keep tent at 80 with lights (300 watt ACI ionboards) at 100%, 5 max and cycling with lights at 80% and filter off Fan above 7 makes to much noise for our comfort level, I don’t have concerns with concealment …closest neighbor is 1/4 mile and I can reduce lights and fan speed if we’re having company over.
Sorry it got a bit long and rambling hopefully somewhat useful.

Definitely useable thank you for taking the time! More appreciated than you know. Love being able to understand numbers and how they are applied to different situations, and learning more. Seems like I’ll need to up the vent size much appreciated.
I’m only worried about hiding because I’m trying to make the room and it’s amenities kinda look like it’s supposed to be there. Outside this room is a game/rec area for kids and who knows who pops up in the future. As far as anyone is concerned it’s just a storage room. Kiddos will be around the room all the time but if I ever need work done I don’t want it to stand out too much.

I haven’t pressed in a while either… need to get bags. Surprised this is the consistency haven’t been able to open it. Lol.

I need more bags also lmao i think i have like 2-120s and 4-90s left atm i also need more flower to press lmfao i want more Devine Jackpot rosin but i also dont want to press all that flower haha

Yeah I get it. Plan on fresh freezing some of the next plants to cut down on material… excited to do that! Won’t need so many damn grove bags.

If temps get to warm you cannalways use a aquarium chiller although thats more investments lol
