Dayton Blowers?

The Dayton blower you are referring to is what I've always called a "squirrel cage" fan. The air is pulled into the larger diameter opening, and is exhausted out the smaller (the square part on the end).

The blower you decide upon will be predicated on the size of your booth. For example, if you have a 2' X 2' booth (2 X 2 = 4 square feet) and considering you should be maintaining about 80-100 feet per minute (fpm) at the booth face then the minimum cfm required should be 4 sq. ft. X 80 = 320 cfm. Adding in filters, length of exhaust ducting, numbers of right angles in the ducting, etc. (all these add resistance and duct transport velocity fall-off), you may want to add an additional "fudge factor" of about 10-25%. Mounting would probably be better at the back of the booth. Airflow should be as linear as possible. Hope this helps you some.

By the way, welcome to the forum family!

Thanks Gip! this will really help, I was going to make a boothe about the same size you mentioned and was only looking at a 140CFM blower.

where is a good placeto buy a blower????


how bout a bathroomexhaust fan??? perhaps two of them in the same booth????



Bad idea???


I have one fan now that i got for free, works semt ok but need something stronger....

I have a Dayton 'Shaded Pole Motor' fan. It has a squirrel cage. The model # is 4CA45A. I beleive it moves about 800 cubic feet per minute, not entirely sure. It is hard-wired into an outside wall in my shop, and it vents right thru the wall straight outside.

Whatever fan you decide on get one with a 'squirrel cage' so that the motor is out of the exhaust flow. This way should you be exhausting anything remotely flammable an inadvertant spark in the motor will not ignite it.

Hope this helps and not confuses!

Brad-

On my blower, the exhaust is the square end with a flat flange, or mounting plate, all the around it. The intake is the circle, or hole, by the squirrel-cage itself. I'm trying to remember where I bought it from. I did have a friend buy it for me. Should I think of where I got it from I'll post the answer here. I've had the Dayton fan for about 7 years now.

That would be great Glen. I have bean scouring the net for a good deal on one.

Brad-

I remember, now, that I purchased my Dayton fan from Grainger about 7 years ago. I'm not sure if they are nationwide or not? I do recall that, at that time, they were not 'open' to the public. Meaning you had to be a contractor or an owner of some business to gain access to their store. But it was Grainger.

It is still the same Glenn. There is a Grainger near me and you have to have a business license to buy anything from them.
They are expensive though.

Well I guess if you want a 'Dayton' fan you have to pay the price...eh?

That all depends. I am sure you will find one on Ebay eventually, but it may take a while.
