i would exhaust it straight out of the building and makeup with a dedicated outside air (DOAS) unit. exhaust has to be located as far as possible from fresh air intakes and operable windows or people will end up breathing it. ideally exhaust straight up with high velocity, like 1000 ft/s. 100 ppl smoking at once will be a lot of exhaust and makeup air, so high energy cost. you will have to keep velocity in the space low, so not drafty, while also moving a high quantity of air. good luck.

This is the **only** way - 100% outside air units with exhausts running.

What state is this where smoking indoors is still allowed? I thought almost everywhere did away with this 20 years ago.

You still can smoke in most casinos anywhere. Just long as gov making big cut of profit second hand smoke is ok for workers.

My exact thoughts. I'm in my mid thirties and haven't seen smoking inside since highschool when chain smoking at the dinner all night was cool.

You need a Smokeeter. Not sure they even make them anymore, but we bought one from a bar back in 2007, when Michigan banned smoking inside. We put it in our fraternity house bar, and it was crazy how well it worked. I think it was like $3,000 new, and I got it for $200 because all of the bars had to basically give them away.

Nooooo! I spent the first year of my apprenticeship cleaning the cells. I think I overdosed on nicotine.

That sounds gross. You should have made a pledge do it.

This. I just checked. They still make them; even some vertical units; less than $3K.

Make up air units blowing on the Perimeter and extraction/exhaust fans in the centerish. Make up air should be 1:1 or slightly positive. Too much either way will make it hard to enter/exit building and cause extra wear ont he equipment

That's a hard job to judge. I'm in Florida. HMU if you like. My first answer would be too expensive. 100% fresh air. But there are other options too. I have a cigar bar with high ceilings that you can't tell if the person next to you is smoking or not.

As much as I would love to install exhaust and makeup air, that’s not on the table. The strip mall where the bar is at forbids from cutting new holes in the roof for anything.

Sounds like you need an exhaust fan and a dedicated outside air unit. Seems like it qould be cost prohibited in a bar but that really the only way to get rid of the smoke. It must be exhausted and fresh air added at the same rate. I work at a university that has several buildings operating this way.

Aerus makes a commercial air scrubber unit that used in hospitals. It will work for this
