Nitrogen AND a compressor

[bubblerboy64]

I’m using nitrogen as my primary source of air power. 6000 PSI which lasts a while but I got to thinking . Since I have a 110 daystate compressor I could maximize my investment in the nitrogen if I could compress the nitrogen by using the daystate once the pressure in the tank drops below 3000 psi.


I’ve figured out how to connect the nitrogen tank to the inlet side of the compressor but I’m thinking I probably shouldn’t introduce already compressed air into the compressor ( would you agree?) 

seems I need some type of step down regulator between the nitrogen tank and the compressor. 


I know this is out there in left field pretty far. Leave a guy holed up in the house long enough he might come up with some wild ideas.


seems a waste not to use more of the gas in those tanks AND I HAVE THE COMPRESSOR ( long story on that) 

And I know I could fill direct to the gun but that’s a PIA some times

Are you rying to dilute your nitrogen? If it were me I would use an Altaros booster and compress the low 3000psi nitrogen straight to your gun with an adjustable regulated tank feeding the Altaros booster that should allow you to do what of think you wanna do empty your nitrogen all the way right? Or boost into a small pygmy bottle too. Yo!

 

[Yo]

OHHH NOW I SEE. you can feed your air intake with Nitrogen? HOW is that gonna affect your filters? Yo!

 

[Metalmaniac]

That sounds like a job for a booster compressor. I would not do that to my Daystate. Too risky for me. Scuba type compressors are designed/ engineered to operate at atmospheric pressure which is 14.7 psi at sea level. 

If you increase intake pressure above design pressure you may get away with it for a while at very low PSI but it will severely increase compressor wear because of increased cylinder pressure and possibly over amp motor.

I think we all want to squeeze that last bit of juice out of things but you got to evaluate risk vs reward. Or extra cash laid out to get that last bit of juice. Not being critical at all. Just trying to help. MM

I don’t see it affecting the filters unless it’s at high pressure. That’s my point. I think I need to reduce pressure going into the compressor ( out of the tank ) 

i know it’s a rather strange idea.


One the advantages of the nitrogen is it’s clean and dry. I can get the nitrogen into the compressor no problem. I made an adaptor that goes into the first stage by removing the air filter housing. So I can get the nitrogen in it’s just my concern about it being already under some significant pressure. 

 

[bubblerboy64]

That’s why I’m asking. Would you agree if I could get the pressure down it should work? I’ve got a external regulator which I’ve used to directly connect a tank to a gun. If it was dialed way back should that not do the trick ? You would need to consider volume and pressure I guess. 


Just brain storming.


reminds me of the fire wood joke. $20,000 pickup $10,000 worth of equipment to save a couple hundred dollars on fuel bills. 


just curious really. I’m not that cheap really 

 

[Centercut]

Why not cascade? Fill your air gun to 3000 with nitrogen then top it off with compressor air from SCBA tank? That way you get to use the N2 until it’s near 2200 or whatever you shoot your guns down to. 

 

[Yo]

Buy the passive Altaros booster (not the one that requires electricity) the one with that manual flip switch look at Mr Hollowpoint video on his dual tank setup. You will understand when you watch it. Yo!

 

[bubblerboy64]

Yes there are a couple ways to do this. I just was thinking out side my box.

I played with my external regulator and I think it would work. What I’ll probably do is when the nitrogen gets down below 3000 pst. I can still direct fill the guns. Once it gets below 2500 I think I’ll might try to compress the nitrogen using my external regulator into my tank ( not the gun) I was able to turn down the regulator low enough that I could stop the flow with my finger over the outlet. That’s low enough that the compressor shouldn’t be harmed.


I very well may decide it’s not worth the trouble 

 

[Yo]

Let everyone know how it goes you're probably the first. Yo!

 

[bubblerboy64]

First man in the moon. It just seems like turning those gas cylinders around with a lot of gas left is a waste. Not so much if the money but it’s a pain moving those tanks around. If they would deliver I’d never bat an eye 

 

[sonny]

sounds feasible

 

[RobR]

My brother proposed this idea to me for my use. He’s rather clever with anything mechanical and it all sounds feasible to me. I’ve yet to try it though.

All that for 20% less O2? You might blow the first stage of the compressor with too much pressure. Like was said cascade until its not worth it. Only thing you might gain is a little dryer gas. 

 

[bubblerboy64]

I don’t understand 20% less 02 . There is is no o2 involved. using an external adjustable regulator I can reduce the pressure way down. Nearly to zero.
You may not understand exactly what I’m considering . I have an adaptor that would feed nitrogen from the nitrogen tank into the compressor. That adaptor would also seal out any room air. If I control the rate of flow and the pressure into the compressor it would be no different then compressing air as far as the compressor knows. 
im interested in hearing opinions I’m trying to avoid room air which is why I’m resisting cascading 

is it worth it.? That IS questionable 

 

[bubblerboy64]

Ok I get it. You are talking about the % of O2 in the air . It’s not that it’s the purity of the nitrogen and the lack of humidity. Which may or may not be significant. 


This project came up as a lack of anything better to do. Who knows what I come up with tomorrow

 

[biohazardman]

Me, I would just fill the tank with what is left in the nitrogen bottle and top it off with the compressor.

 

[RobR]

All my assumptions but it seems like the amount of gas needed at the intake would vary as pressure builds. A slight overcharge I would think would only ease the load on the compressor but pulling a vacuum on intake I don’t think would do it any favors. 
Put an amp meter on your compressor and a full face helmet and flak jacket on yourself and give it a go. 

 

[Enazle]

A YH compressor need 2cfm or 50l of gas per minute according to the manual. At 1/8" it takes 30psi to supply that amount of gas. I setup a paintball stabilizer at 30 psi to supply the air into my YH. Once running the intake creates a vacuum so as long as the intake side is above 1 or 2 or 3 psi the compressor will not be starved of air and all should work according to plan. I have all the parts and pieces now so sometime in the near future I will be putting this to the test.

 

[lenweber2]

I do exactly understand what you are wanting to do? 20% is the difference between air we breathe and the nitrogen tank gas. What are you trying to gain? If it's to stay with dry nitrogen you have a point. If it's just gas to shoot with whats the gain in time and money?
