Ventilation Question

[WNYTONY]

So now the question is "where would you install the two 6" circular exhaust grills"?

Im trying to take in the location of the HVAC supply and where I think I'll have a couple chairs and a coffee table. Take a look at my awesome drawing below (not to scale) and tell me where you think you'd put them. @WNYTONY @Nature @josh lucky 13 and anyone else with thoughs

That's pretty funny TJ, although you shouldn't sound so shocked that he stole my setup. Ha, of course he would beat Amazon going the wholesale route... he just had to get in that dig didn't he. I already like this guy.

Don't know if it's the same cfm as my 360 and I'm not an HVAC guru or anything but I'll give me you info so my new buddy can use it to bill you

I'll say in my room I put them on the middle line running the longer measurement and I spread them equi-distant along that line - a snake eyes pattern on dice. In your diagram that would roughly put them between the chairs and table and on the outside corners of the 2 chairs. I'll say that it looks fine visually just splitting the distances but I also liked it because it put one above me and the other halfway between me and to door and that was what I felt would work the best to keep it from exiting the room.

Now the difference here between yours and my setup is with mine that puts one pretty much directly over my head and the other about half way between me and the door. Yours in that configuration would both roughly be right above your chairs.

I will also tell you that with my 360 cfm it does not grab the smoke and funnel it right up thru the grate. It circulates the air and pulls it out but I don't exhale and it all runs up like a tornado into the grate or anything. If you've amped the cfm maybe yours will be different.

I also have a floor grate for my HVAC and do have a cold air return I have shut off. It's forced air heat, but we rarely need to run air here in NY. I don't have a problem with the incoming HVAC out running the exhaust - it is still pulling air under the door even when the heat is running, just not quite as much. In the summer I will use a window fan and/or a window A/C unit but when I'm smoking I will run it on the lower setting so it doesn't outrun the exhaust. Still, not a problem.

Just looking at your room setup and not being an HVAC guru - I'd still look to put one over the chairs and the other halfway between the chairs and the door. But if that will work or not is I guess dependent on the cfm of the exhaust, how powerful your HVAC is pumping it in and whether or not you close off the cold air return. You'll have to consult the expert on that.

In the end they're just holes in the ceiling - you can always relocate them and patch up the old ones if you find out it's not effective

I can't help but like the guy, he cracks me up. He was supposed to go discuss it with a supplier and get back to me. He disappears for a week (told me he'd be gone for a long weekend), then just shows up with product inhand. (Literally called and asked if I was home- I'm thinking he needs to see something and will swing by - But he says "Good, I'm in the driveway" - lol). Now he did say I didn't have to keep it, but said his supplier guy agreed, followed by the Amazon line - lol.

Tony, I want to say its 370 cfm? That should turn the room over in under 4 minutes and 99% of the time its just going to be me having a cigar in there.

So right about the same size as what I have and I did that math too. I just wanted to tell you that mine doesn't suck the smoke right outta my mouth or anything and you're probably going to immediately be unimpressed and wishing you went bigger. I wanted to go big enough to be effective and not pull the hat off my head but like I said I still leave it run some afterwards and supplement with a scrubber. Just don't want you thinking this will be magic or anything - smoke and smell do take a bit to clear.

Totally understood and appreciated.

I don't think there is a "right" answer; its more of a personal preference rooted to the size of the room and number of smokers.

Can't wait to see how it turns out - especially that walk in !
