I'm checking a job(nail salon) that requires ventilation. The safety inspector left a paper with the owner that says that "systems shall be capable of exhausting a minimum of
50 cfms per station. Has anyone run across one of these? The business I am looking at has around 6 chairs for customers. I'm guessing that if I put a 300 cfm fan in the middle that should do it. I left a message with one of the inspectors, but they have not returned my call. Any ideas?
Thanks

I'd ask the inspector! Better yet, find the exact code he's using, and see what the code says.

Evacuation of solvent fumes is a BIG inspection issue for nail salons. Be sure to take into account the cfm lost in every bend of the pipe. Be sure to provide for make-up air.

As I recall it, the ventilation needs to be present at each station; general room ventilation won't satisfy the requirement. They might let you put the fans on timers. I quoted one such job, only to have the owner choose to play inspection / responsibility games instead. Oh well. frown

sparkync:

A ventilation system for nail salons here is required to have a plan prepared by an Architect or Engineer.

Usual is a 'common' exh fan, trunk duct. and a 'drop' at each workstation. Some have a 'on/off' switch at each station, some are a 'one switch' control at reception.

IMHO, the mechanical install of this type of system is best left to a mechanical contractor (HVAC).

I agree with John. Just ask the HVAC guy where he needs the power and be done with it. Around here, he needs to run the duct anyway if it is more than a short 4" flex to the nearest "out". (no venting in the attic or anything)
