Looking like we are going to be rocking a shit load of fume hoods and air circulation instead of C1D2 booths. Anyone have a recommended supplier or fabricator?
We will be buying quite a few

Your better off buying used restaurant hoods and upgrading the fans. This is the best way to avoid the green tax.

Are you just doing massive air circulation (I think the requirement is 6 times per hour) or are you also doing C1D2 fixtures and electrical components?
I’m looking at these guys for our facility. Get 4 10k cfm or whatever you need and you are moving some air. They have a calculator to determine what you need.

so because we are in florida the rules are wierd and lax. im meeting with the fire marshal this week. But it looks like as long as we have spark proof light fixtures and the proper amount of air circulation thats all we are required to have.
Lax is good as long as you are safe. Just spoke with the marshal in the city we are looking at he’s the same way. Sprinklers and circulation.
More than likely you will be required to use a large makeup air unit to provide all that air your hoods will be removing. From our experience it’s best to not oversize the cfm leaving the building, cause you will need more cfm pumped back in and that equals a large and very expensive makeup air unit.
Your regs and city will likely be different. But obviously you’ll have a negative pressure in your building if your sucking out too much air and not replenishing it. My 2c.
Very true. At our place we can just open the bay door.
I’ve had good success with used Hemco and Labconco For benchtop hoods within the range of $500-10,000. I usually buy them without an internal exhaust system and purchase a separate ignition proof blower/ducting system and rig it up myself. If you’re looking for the floor to ceiling type that’s going to get more pricey and involve a more complicated buildout.
