Ummmmmm Ultgar, What exactly do you do for a living? And are they hiring?

That is quite the system! Beats the old hose stuck in a hole in the garage door.

Ah I see, makes perfect sense now. Thanks. I have seen some of your work it's very nice stuff. And I guess we do sort of work together as there is a reference to my company on your page as well.
Cheers

Hey, ultgar, not to thread jack, but tell me about the solar cells on the garage...

maybe but the ol hose through the garage door dosent cost$6500 freeking dollers either
some one has more money than they know what to do with

What would it cost for just the fan? Ill get some sheet aluminum and 6 inch PVC to make my own ductwork.

UltGar, do you have any pics showing what the exterior of the venting system looks like?
Sir Loyn of Beephe said:
I'll have to go up on the roof and take a picture of that .....it'll have to wait until the snow melts. Its a butterfly flap that opens up when the fan blows. The noise and exhaust goes straight up and out...you can see the ductwork coming out of the fan in the picture at top just about to go through the roof.

the way ive done it is with a couple of 10 ft tiles and a 3 inch 16 in peice of tail pipe with adapters for other sizes in to a hole in the side of the garage
sounds crude but given the right preps and equip it turns out nice and factory done

I'm thinking of dryer ducting from home depot and some sort of small/high power inline fan. It may not be pretty but it should work.

When it comes to health and safety, I don't believe in compromise. LD, as an "Engineering Student" according to your profile and a future engineer, you need to ask yourself the following...........
Are you trying to simply ventilate the room or capture fumes at their source?
What type of particulates and fumes are your extracting? Welding? Vapors...what type? Are the vapors explosive? Particulates? Oil, dust, etc?
What is the static pressure of the system?
What's the best type of fan to use? Does the fan need a starter with overload protection? Is the fan motor isolated from the exhaust stream? What about switching and control? Speed control? (note - order a 3phase fan and a nice frequency drive ....I like the AC Tech units....see http://www.actechdrives.com/home.htm ) if you need to vary your motor speeds. As you probably know, there are no speed controls for single phase fan motors.
What type of source capture system? Rubber nozzles, steel collector hoods?
What type of hose? What diameter hose? Temperature rating?
Is the garage attached to the house? Is there adequate make-up air?
What about exhaust fumes and the neighbors?
What about noise levels and the neighbors? Fans can run for extended periods as needed (15 minutes to hours at a time). As you live in Tampa/Hillsborough County, anything over 60db (at 63hz,125hz,250hz & 500hz) between 10am and 7pm as measured at the property line is a problem. Go to the property lines of all your adjacent neighbors and with a hand held spectrum analyzer, record the noise levels of your fan system to make sure you're in compliance. Florida is tough on noise pollution. Conversely, if you lived in Charlotte NC, heart of Nascar, you could probably run open exhaust cars on dynos day or night with the doors open.
And finally and probably most important...........What would the building inspector say? If commercial, would OSHA approve of the work environment and equipment?
As an engineer, a simple anamometer will help you evaluate the performance of your system. This will allow you to measure air velocity (ft/min) and air volume flow (in cfm).
There are all questions and issues I have to take into consideration with every project and why my systems start at around $2000. Good luck........Steve

More on the topic of fume extraction:
I'm sure that everyone is familiar with your basic carbon monoxide detector that sounds a warning beep at a preset CO level.
Suppose you were to to instead of sounding a beep, use the same device to close a relay and turn on a ventilation system whenever the CO levels raise, but have not yet become dangerous:
Sort of a pre-emptive strike, if you will.
Tailpipe extractors are all very well and good, but as any who's done a fair share of arsing about with cars in general knows: Sometimes in the midst of a project there simply isn't a tailpipe, or something in the eshaust is all fouled up, or you get all sorts of carb blow-back or any number of nasty things can happen where having a suction hose on a tailpipe won't really help you.
And while UltGar's system there is something worth drooling over (as is the rest of his set-up), you do have to admit that the normal mere mortals among us are more likely to spend that spare $6500 or so we have laying around on the car itself than on making the garage a safer and more pleasant place to work in.
Which makes a removable and portable system probably more tempting to me: I envision sort of a condensed version of the same thing shown here, except put that big squirrel cage there on a cart, and put a regular 220/30A cord and plug on it, end for the exhaust make a sort of quick release connector through the back wall or door of your garage that the fan can hook up to.
Sure, you'll have one more ****** thing to find a place to put , but you'll have vastly less installation costs, greater portability to your next garage or shop; and you'll be able to use that big squirrel cage for other things as well; such as blowing the water and slush off the floor in a hurry, sucking the welding fumes away from your workbench, and of course you could disconnect all the hoses entirely and just use at as a plain old fan on warmer days.

Steve- Yeah, I know it's not the best solution. Just trying to give some ideas. I personally have a 5800cfm window fan running and the garage door fully open anytime I run an engine in the garage. That more than takes care of any fumes for me. At the same time though I primarily do motorcycle work (<1000cc's)so it isn't near the amount of exhaust of some cars.
Don't tell my homeowner's association about that 60db limit, I don't think they have caught on to me yet.

Luke......for car exhaust fumes, that's the cheapest way to go. A wall or window mounted fan on the wall opposite a slightly opened garage door will give you good cross ventilation. If the garage is attached to the house, you need to make sure you're pulling air from an outside source and not creating negative pressure inside the house.

I found this product on ebay and then searched the web many tool vendors sell Crush Proof hose. It is pretty cool Stuff http://www.crushproof.com/garagehose.html I purchased the twin pipe kit on ebay for $115 and then picked up an 11' extension and 2 different sized bell shape attachments. When I install the system I will be using a combination of the Crush proof hose, metal ducting from Home depot, and a Craftsman variable speed leaf blower to move the fumes outside.
Does anyone see a flaw in my plan? I am going to hook the leaf blower up to a power socket controled by a wall switch. For under $300 I have a pretty kick *** fume extraction system.
This is the guy I purchased my CrushProof hoses from he shipped quickly great experience.

Remember, ultgar's setup is built to take into account use of the car on a dyno, which involves high RPM and thus, high exhaust output. Much different than a system designed for lower RPM.
BTW, I bought a brand new Navy surplus centrifugal fan off of eBay for my garage.

I just got the blower today one side has a 6" wide tube that can be used to vacum leaves and what not the other end blows into a bag or you can close the input and use the tool as a leave blower. The high speed is very powerful. I won't be running a Dyno however I think this will serve it's purpose well.
