Exhaust Fan

[OldMedic]

I did a search, all I could find was stand alone fans and barn fans...

I am building a bit of a motorcycle workshop for my own use, not commercial. I have three windows in the shop that all open, however I was wondering about the use of a higher flow "bathroom" exhaust fan.

Easy to mount near the work area, really easy to vent out the side wall..

The intent is to get rid of the fumes from a small amount of spray can painting, the use of brake clean, etc. and sure the occasional runnig of a motorcycle for short periods of time.

I looked at a 12" barn fan, and while not super expensive, the quality is not there, and I am concerned about the lack of sealing the cold weather out as it relies on a single louver system to stop "cold" air from entering my workspace.

I would prefer not to go up through the ceiling...

Thoughts?

Nobody has done this?? hmmmm.

I have the highest cfm bathroom fan I could find at lowes in my garage. Its primary purpose is to vent cigar smoke in the winter, which it is adequate at doing. In a smaller space it would work quite a bit better.

I had the same thoughts. I have a 130cfm bathroom fan, and although it seems to move lots of air, I'm not sure if it would be enough. Barn fans move lots of air, but as you mentioned, probably leak in the cold badly in winter.

Barn or attic fan, in a cabinet with an insulated door. ???? I did that in a shop I had years ago and it worked fine. Just open the door when you are using it.

I saved the old cooker extractor hood when we redid the kitchen last year, plan is to mount it over an open fronted wooden box and duct it outside, has built in filter (cheap and easy to get) and enough suction for removing paint fumes from painting small parts. I'll probably put a rod across for hanging stuff from whilst it's being painted, free and should do the job.

Great idea for fume extraction, I'll scan craigslist for a used kitchen hood and fan to install in the basement for when I do painting down there.

I think the kitchen vent fan is a great idea.....

I also did the bathroom fan thing for my wife - who's a smoker - in a room in the upstairs of our house and it helped, but didn't really clear the air like I hoped it would. She now smokes outside....

A small bathroom fan isn't going to work for carbon monoxide fumes from the bike. Carbon monoxide needs to be captured at the source and removed ASAP. At least use a hose through or under the door...

Also just using a fan doesn't work, it needs to be "tuned". Seal up the building and crack a window or walk door to get the "pull" right to move air. It really wont ork well till one understands this,,,, http://finishingacademy.com/training/aero/aero_mod3/aero_mod3_intro.html

Do those actually pull, or just make noise? I swear every kitchen I've been into they just seem to make noise. Even with the filter off, only minimal air is being extracted.

I had an a 24"industrial type exhaust fan in my last garage.The ones with the louvers that open up once it goes on.I paid $150.00 in China town in NYC in some industrial supply store.The thing would clear out auto paint smoke in my 900 sq ft. garage in minutes.It was worth the money to put it in.I just finished up my new shop down here which is 1100 sq ft.I ended up buying a Maxxair Fan from Tractor Supply.It seems cheesy but I really haven't put it to the test yet.I would look into an industrial type fan.In the long run its better to have too much than not have enough.

Its only really going to "pull" if the intake to the room is restricted. It will exchange some air but not create directional air flow.
