Hello everyone, its my first time posting a question. I did try first to do a search but couldn't find what I needed. My wife has a lady salon and she would like to install 4 inlet fume extractor for the 4 hair treatment stations. Each opening will have a 16" hood that attaches to a 6" 1.2m long flex hose. That flex hose connects to a 6" 3m long solid duct pipe. and each of the 4 opening is connecting to the main 6" solid pipe by a T-Y connecting style connection to avoid the sharp T style connector. My question is, what is the appropriate fan size needed to insure proper suction performance at each hood opening? assuming all 4 will be working at the same time. Also, is there any advantage looking at Centrifugal Blowers vs. In-line fans? Thanks in advance for any help and support P.S: we're in Kuwait, and over here there are no building codes what's so ever.

Hi, I am trying to replace the microwave over my moms stove with a vent hood. The micro is too close to stovetop and this is more of an issue now that she is older than it 26 years ago when my dad installed it. Not to go into the story too much, but there have been a couple close calls. Anyway, micro is plugged into outlet and vent is set up for hardwiring. This plug is in the middle of a circuit, so I would prefer to find a way to get the vent connected that does not require removing the plug. Any suggestions would be greatly appreciated. I have today only to try to get this done.
