Fresh air mask suggestion

[fosterjeff00]

I have a few questions about a fresh air mask.
I have an 80 gallon compressor running into a winded 50 feet of copper. Submerged in water, from there it goes into a moisture trap.
From the moisture trap goes into the tank
Then from the the tank it goes into a 60 gallon tank. From that tank I have about 50 feet of copper with 3 drain valves
After the drain valves it runs into a refrigerated dryer. From the dryer I have a 3 filter setup
From there it goes into my hose reel.

My question is would I be safe to run my mask? and the mask filter does have activated charcoal

Nope. I would never put my lungs up to a typical filter used for air systems

Oil in the air is the main problem with using compressed air for breathing. You need an oil free compressor and the right filtration

This is a fabulous book and read: https://www.penguinrandomhouse.com/books/209340/trapped-under-the-sea-by-neil-swidey/

If you read it, this idea of breathing off a regular compressor will come completely out of your mind!

Okay thank you I will look into this

Be better off running an ELECTRIC blower, like a new shop vac in clean air with a hose to your hood. Not that I would ever suggest doing this.

They make oil-less compressors for driving a face mask. I have one and have used it for painting.

Okay I gotta figure something out

PAPR

PAPR

Isn’t that normally mounted on the body? I am assuming the OP wants fresh air pulled from like 50 feet away. There is some stuff even a respirator can’t filter out so you need fresh air.

If the OP is dealing with stuff a proper PAPR can't filter, he has a problem

I thought a lot of automotive paints recommend a supplied air respirator? There is something in polyurethane that respirators can’t filter out, but hardly anyone uses supplied air with polyurethane.

IIRC, it is the isocyanates in the urethanes that favor the use of external air supply. I use a Turbine Products Breathecool system when shooting paint, and also have a sandblasting hood that I use when sandblasting. Allows me to get those jobs done without triggering my late-in-life-developed asthma. The system was pricy, but so was the emergency room visit when I couldn’t breathe before I bought it.

I have the HobbyAir2 Full Face Respirator system - I use it when spraying 2-Part paint. IIRC, it's one of the most affordable supplied air systems, I think I got mine under $600 a couple years ago. Might have gone up since, but definitely something you need when working with isocyanates.

Yes any urethane based automotive paint recommends a supplied air respirator. It's not that the filters can't filter out the isocyanates its that most people don't change the filters often enough so lose the protection. People wait until they start smelling the paint through the respirator and at that point its too late or they get focused on painting a car and simply forget to change them often enough. Especially if you are painting in an environment that is not being properly exhausted filter life can be surprisingly short.

And according to what I read some years ago after I got lung damage from the stuff, there is no practical way to test the usable life expectancy of a cartridge for use with isocyanates because there are too many variables. The only good respirator for the stuff is a proper supplied air system with the pump located in known safe air.

Agreed - if you’re serious about doing paint work, there’s no replacement for the safety of a supplied air machine. The price is definitely a gatekeeper for a lot of people, unfortunately.

Yep. But losing the use of your lungs forever is kind of a bad trade for saving a thousand or two on a paint job.

"Many of the sources of contamination discussed in our blog about Carbon Dioxide can also be sources of CO contamination. Like CO2, CO in compressed air mostly comes from either the compressor itself or from the air your compressor takes in. CO is a product of incomplete combustion, and some compressors have oil based lubricants that can heat up and produce Carbon Monoxide. In this instance, your results may also show elevated levels of Hydrocarbons. Ironically, if your compressor has a charcoal filter, your filter can oxidize if the compressor runs too hot, resulting in the filter contributing CO to your breathing air rather than preventing it."

You do not have a Carbon monoxide filter, are you planning to win a Darwin Award? Unless you have a high capacity CO filter with ability to monitor CO levels, with an oil lubricated compressor, you may win that award.

Get a HobbyAir2 Full Face Respirator system or equal, even cremation will cost more than a fresh air system.
