View Full Version : HPA question:

11-08-2008, 11:18 AM
I picked up a 3000psi tank for 20 bucks . seems like a good deal .

The guy didnt know if it was regulated at 850 or 450. He did say he used it on alot of differetn guns and its always worked fine. There was only a tiny bit of pressure in it but it fired on my mr2 in burst and sounded just liek co2. I only got maby 10 shots out if it before it went empty.

Is there anyway to tell what its set for and if it is to low cant it be changed?

Most HPA Tanks aare preset in the 800psi or 400psi range. To test it, get it filled at your local field & screw it into an ASA with a gauge on it.

if it burps you need to up the pressure in the reg.

Get it filled, and then try it out. You should be fine.

what brand is it? i believe crossfire LP tanks have red bands around the neck, and HP are blue. what size is it, 48? thats about how much i got mine from my friend for (with 4 years of hydro left)

Wrong, other way around for Crossy's. Take a picture of the tank and let's see it. We'll be able to tell you from that what it is. Also, get a picture of the indentations that are the DOT code along the top of the bottle so we can check that out and ensure that it is still hydrostatically sound.

cant find my camera , but it is a crossfire 3000psi ( gauge reads 4000 but in )red)

dot is 3al3000


It seemed to fire fine on my mr2 sound wise that is. but had no paint to put through it

there should be more on the label, i think were going to need that too.
Just keep in mind the regulator on the tank will let enough air out to power the gun. If it is sputtering, or not operating right something is most likely wrong with your internals. so check that too.

Make sure you take care of your gun regularly too!

Yup, that's a 5-year hydro tank with a 3kpsi fill limit, most likely a HP tank. Look for a date on the indentations as well, should be separated by an "@" sign. Such as: 04@09, as in 04/2009. That's the birth date of the tank. Make sure that it is within 5 years of that date so it is safe to use.

used the gun today and it worked fine . gun chronoed low with the screw all the way out (like 200) but after a few shots it was hitting 280( screw most of the way in )

tank seemed to work great .
