Homemade forced air respirator

[cozybldr]

I remember seeing in either the Canard Pusher or the Cozy newsletter about somebody who built a forced air breathing system. I believe they used a respirator mask with one of the cartridges removed, vacuum hose, cooking pan, and a squirrel cage fan. I seem to remember duct tape in there as well. Does anybody remember which issue had that series of pictures? I want to construct one for myself. Yeah, I could plop down $600 for one already made, but this is homebuilt aviation. We ought to be able to do it for a whole lot less.

The only type of 'fresh air' mask that I am familiar with runs off of a compressor that you place outside of the shop and it is usually associated with painting.

 

If this is what you are looking for, it's a very expensive corner to cut. Some of these paints will kill you before you can get to the door.

 

If your intended use is for another application ........... never mind.

I saw an article in Kitplanes about 10-13 years ago. Central States newsletter had one article also.

The guy used a bathroom vent fan and all the hoses and duct tape used were from home supply stores. He built the whole thing for under 50 bucks. I just replaced my old mask on my machine with a respirator from AO Safety for 20 bucks. A garden hose with quick disconnects that won't collapse as your moving around the project works well. I think food grade clear hose from the hardware store works well.

A pool hose can also be found at the hardware/lumber stores. Mines a commercial HVLP system. The pool hose would work better for the bathroom fan to move a larger mass of air.

 

I use fresh air for sanding and all other things where there's lots of dust and nasty stuff in the air.

That's the one! Do you remember which issue that was in, please?

 

Thanks,

That was the system I was thinking about.

Very effective as I remember in that the guy tested it using acetone fumes at 3 inches to see if he could smell them. He couldn't and I believe he did it because of the epoxy fumes.

 

Thanks!

I developed the allergy to the epoxy's and I use mine a lot. I wished I had used it more when I was building a lot. I may pay a price later in life! I also use a hood and sometimes wear a full tyvek suit when actually painting. You can't be too careful.
