[goldnugget77]

Hi Harold!
I called the place you purchased your blower fan and because I am in Canada they said they cant serve me
So they gave me someone here I can call.
I called them and sent this picture and all the info you provided

hood moved roughly 1,000 CFM,
Static Pressure that this application will use
It is also a paddle wheel, not a squirrel cage

Harold if you can give me this info that would be nice

The blower I used was purchased from W.W. Grainger. They are described as a radial blade blower. My memory of the specs is apparently not good---but I believe the one I used was their number 2C863. Size yours according to the amount of air you care to move, or by the size of your discharge and/or intake. I used 8" asbestos pipe for mine. As I recall, the pipe had a hub on one end, which, with a rubber gasket around the inlet, fit the hub quite well. I fabricated (from pieces of asbestos sheet material) the discharge adapter.

Hi Harold
I think you already mentioned this before about that fume hood
Was it made from asbestos
I think they treat asbestos so that it is not harmful.
As long as asbestos is not in dust form in the air then everything is OK.

How about making that fume box or fume hood from aluminum

How about making that fume box or fume hood from aluminum

bad idea

 

[PreciousMexpert]

I dont see why aluminum would be bad.
I also thought about galvanized steel
or any there suitable metal painted with epoxy paint

Take a couple of drops of hcl and put it on a piece of aluminum foil. :shock:

 

[golddie]

I think Galvanized steel should be good or stainless steel or steel painted with epoxy

I remember someone using gyprock that is also fireproof.
So if you have a sheet of galvinazed steel and have gyprock behind that

Thats me. I'm using HardieBacker 500 www.hardiebacker.com
Its non combustible and I'm going to paint it with epoxy appliance paint to give acid fume protection and make it easy to keep clean.
I bought it a Lowes.

Hi dick b
So boards are non combustible.
If you have galvanized steel in the interior of the furnace than you can use it for burning things like Harold did.

 

[golddie]

So you bought one of these
Cement Board
Are they like ceramic

 

[Harold_V]

The boards in question won't serve well unless coated (they are made of Portland cement, which readily dissolves), and if coated, they won't tolerate the heat involved in incineration. Not a great choice for a fume hood, in general.

To my knowledge, there are NO (affordable) metal alloys that will serve well in a fume hood. The combinations of acids we use will attack almost everything.

Hello Harold:

Ouch!!!

I didn't see that arrow coming, direct kill to the heart.

This is what I am building my fume hood out of. I have sized it as a hobby refiners hood. 51 3/4" wide, 27" deep and 37 1/2" high. It was the most suitable material that I could come up with that I felt was acceptable to construct it out of. Yes the board is made up of portland cement and silica, it is non combustible and needs to be coated with epoxy or the acid fumes will react with it. But the price of the board makes it an acceptable resource for me to use.

I'm not telling anyone here that this what they should use, only it is what I am using.

Thank you for your input.

First let me say that asbestos kills that is for sure.
But it is important to know a bit about this mineral.
I remember reading about all those people that became sick because of contact with this mineral.
Those were people that were constantly breathing the asbestos dust.
Also a women working in a barber shop had her fingers deformed because she was washing the hair of the miners.

All jewelers have a board of asbestos in their shops
I remember being in a room fool of asbestos dust
This happened about 20 years ago and it was only once .

What I am saying is people exaggerate the dangers of asbestos.
If it just stays there and there is no dust coming from it then there is no danger.
