Is 60 psi enough for fresh air system w bullard mask
Just got a 5.6 cfm compressor to run fresh air system. In line filter etc.

I hear 5cfm per mask.

ComP will only go up to 60 psi. Is this enough for a grown man ?

Is the pressure switch adjusted properly?

We're looking to upgrade fresh air system. What did you get?

Man this site is a great way to procrastinate. Hope the boss isn't looking.

Do you seriously want 60psi at your mask, because I sure as hell don't...? Have you ever worn an SCBA or used supplied air before?

It is my understanding that OSHA requires 4 cfm's at the mask, and 6 cfm's for hood application. PSI or CFM's, hood or mask, compressed air or blower systems. What were you using when you stated spraying? Chances are you still use the same respiratory system that your first rig had. You owe it to yourself to shop, summer is weeks away. Take 10 minutes and pull up the Tennessee Chill Box. 85 cfm's with a chill factor of 46 degrees. We have high end insulation companies running 2 or 3 lines with one, small, 65 lb portable system. Mask or hood, this summer you deserve it.

The pressure knob is all the way up (Seriously?) lol.

What I am saying is, while the compressor goes up to 200, when my mask is attached, it goes down to 60 and stays there.

I am just trying to confirm with people in the know, that 60 is just fine and will not cause the contaminated air from the 'out' hole in the mask to come in on a big breath (following me?).

The one person I asked said it is okay.

I would jsut like to confirm with more than one person, so I can spray without worry. The one job I did with it went fine and I had no headache as I have had in the past when accidentally breathing in a breath or two of fumes while testing the gun in the back of the truck alongside the machine.



And no lol, I don't want to buy your products o.O

It sounds like you're quite confused...

You'll only want 5psi or less at your mask, it is the VOLUME of air that counts not the pressure.

Your compressor isn't capable of maintaining 200psi at the volume you're using air is all.

So at the air filtration panel i have, the knob with the pressure gauge before my air line to the mask should be set to 4 psi? It goes to 100. Sorry if i had this wrong.

I just can't believe it really.

You can't believe what?

Go ahead and put the mask on and try it...

I guarantee you wont even keep the mask on your face at 100psi...
