powerrodsmike adn999-Feel free to discuss the technical aspect of nitrogen spray systems here, but you may not put a link to your company in your post. Please see our commercial posting guidelines.

Nitrogen for Spray Painting

There is a local USA company that is really promoting the use of Nitrogen for spray painting - ****************

The Gentleman in post 97 had stated that nitrogen is good to purge the air out of a paint container, I don't rmemeber him saying anything about it being flammable.

Turning Nitrogen into gas

The liquid nitrogen Dewars I work with have 2 valves...a liquid and a gas valve. The liquid fitting has a dip tube that uses the naturally occuring pressure that develops to force the liquid out of the fitting. The gas fitting takes the pressure that occurs right from the top. Liquid Nitrogen boils at something like 300 degrees below zero...so it is always creating pressure. I know of 3 kinds of dewars...low, medium, and high pressure. The pressure rating depends on the pressure rating of the dewar, and the rating of the safty...the higher pressure the safety the more pressure it allows to build before it opens. Never keep a dewar in a enclosed space, it will push out the oxygen

deadbodyman We had a couple auto condensers hooked up to ours that worked pretty well too..I always thought An old refrigerator with a few condencers inside would work but I never had the need here..
Dont they use nitrogen/oxygen mix for diving?I remember something about Nitrogen narcosous,where the diver gets drunk and has a good ole time, forgets to come up or gets lost in underwater caves and dies

powerrodsmike I had a dream last night that someone here was calling my name...so my dreams really WILL come true...

Yes DBM, this is a fun thread, lots of good stuff here...One of my very favorite threads as a matter of fact...This is the one where someone said that N is flammable...

I think an air dryer would do a better job of drying your compressed air, as's been said up there in the first few posts, the air we breathe is already almost 80% nitrogen...

About 20' of coiled copper line aimed down with a drain at the end before it hits the main air lines works good...Works jus' like granpappy's still up in that holler.

...HEY how did I get on THIS thread ?I wasnt even a member then ,08 This isnt the thread I responded too.Makes for some interesting reading though.I learnd a lot about compressed air..Maybe nitrogin could be introduced into compressed air as dryer???
I wonder what would happen if you sucked all the nitrogen out of a big bag of chips like a helium ballon? I aint gonna try it .....Lets get Mikey ....hey Mikey...

I think you misunderstood the gas statement. he was refering to taking a liguid nitrogen and turning it into a gaseous nitrogen.
As far as painting with it there is a Europeon system that uses heated nitrogen.

enough Nitrogen to paint with

I work for a company that handles Nitrogen gas containers. you can obtain 6,000 psi Nitrogen cylinders and if that is not enough for you there are Large Nitrogen Dewars that generate gas from liquid nitrogen...hope this helps

95 Ponyboy I have applied clearcoat using bottled nitrogen and it worked great. Nitrogen is dry and will even further dry the surface you are painting by displacing any surrounding moisture. I used it because I had no were to paint so I went to my brothers property tied off some plastic sheathing and went at it. (SHH don't tell the EPA). Just needed to dress up the car to sell. The portability was great. You would need a full size tank like one of those 4 or 5 foot tall ones to do a whole car i'm sure. I used small bottles I would guess 20-40CF 2000 lb not even the size of a 10lb nos bottle. it took maybe three bottles but I sprayed it on pretty thick. It costs less than one dollar each where I work to fill these so cost isn't an issue.

Old Fool Todays activator reducers and hardners are moisture sensitive. Why not have a small bottle of N2 and fill the container after a partial use? Would that not keep the shelf life closer to a non opened container?

How about a shot of C02?
Or Argon?
Or propane?
or a commercially available product called Bloxygen?

food for thought
