psi?

NapervillePBaller · 07-13-2006, 01:05 PM

Hey guys, I'm a bit new to compressed air systems and I need to buy one. I was wondering what PSI means and what it's function is. I know what ci is, no help needed there. But whats the difference between a 3000psi and 4500psi tank? Any help is appreciated.

Per Square Inch
PSI helps because well it gives you pressure to shoot. Your gun runs at a certain PSI too, if it didn't have any pressure to push the air into the marker ti wouldn't fire.

The only difference is more air in the tank.
The psi refers to the ammount of pressure pushing out on the tank itself. The higher the psi, the more air in the tank.

pounds per square inch...what the pressure is...the higher pressure it can hold the more air it can hold the more shots you will get....the more it will cost

Ha the only real reason it cost more is the market and that the materials that they are made of are higher quality, and actualyl help hold the pressure. Believe me, don't try to put 4500 psi in a 3000 psi steel tank. It is fun...

thanks for the help guys. By the way, i'm on a budget right now, and probably will be for some time. do you think it would be a better idea to spend more for a higher quality n2 tank than a cheaper one? cause if i buy a cheaper one then soon i will want to get a better one. lil help?

its better to wait and get a decent fiber wrap, but if you really wanna play, you can get a steel 68/3000 for like $70

Ok guys thanks again.

Yes just wait and buy a tank that you wil use for a lonfgwhile, and something that you can use with many guns. I would suggest a Geurilla Air Assault 68/4500. They aren't as expensive as some others out there, but are extremely good.

PSI can refer to the amount of pressure the tank can hold, which will be either 3000psi or 4500psi. the more pressure the tank can hold, the more shots you will get out of the tank. the guage on the tank will tell you how much air you have left in the tank.

there is also "output pressure" which is the amount of pressure the regulator on the tank will put it out. It will either be high pressure (HP) which is either 800 or 850psi, or low pressure (LP) which is 450psi.

Output pressures can also differ from company to company. I know my Crossfire HP Tank runs at around 750, but my friends Air America HP runs at like 850.

you could just go ajustable..

But that only changes the output pressure not the over all psi rating of the tank.

paintdude171 · 07-13-2006, 03:28 PM

yes, i know, but it solves the problem of there being 100psi differences in high pressure tanks of differenc companies, and sometimes more then that on low pressure ones

Oh I thought you were talking about the rating of the psi of a tank. Sory about that.

you could get a fiber rapped 68/3000 for $70 if not cheaper if you look hard enough. *used of course tho.*

get a carbonfiber wrapped one not a 48/3000 aluminum or steal carbonfiber weighs like nothing

paintdude171 · 07-13-2006, 07:46 PM

you know its not carbon fiber, but fiberglass right? and its wrapped around aluminum

ci= cubic inch
psi= pounds per square inch

68/4500
first # in the size of the tank in cubic inches and the second # is the amount of pressure in pounds per square inch
