FAQ part II

  • Buying used HPA tanks!

    Yes, a HPA tank is quite an investment, and the fact is if you want better performance, your going to have to pay more for it. I highly suggest buying a BRAND NEW HPA tank! However if you do want to buy a used tank it's totally up to you, but please consider this... What is the date of the tank? how soon are you going to have to re hydro the tank? Is it in good condition? Is the seller honest, and telling you all there is to know about the tank, or is there something wrong with it?

    I have seen a lot of people buy used tanks without knowing what they are getting into, and in the end the buyer ends up with a broken, out of date tank. If you are going to buy online, please buy from a trustworthy online store. I do not suggest buying a used tank off of Ebay! Just be cautious when buying used...
  • Co2 Tank Pressure

    "What's the pressure in a CO2 tank?s long as there is liquid in the tank, the pressure in a CO2 tank is determined ONLY by the temperature"

  • How Do I Fill My HPA Tank?

    Simple, take it to your local paintball shop, and they'll be able to hook you up there! If you are looking to fill your own tanks, then first you will need a Scuba tank, be sure you are getting a scuba tank that is rated for at least 3000psi, not getting a 3000psi tank doesn't mean you cant fill your HPA tank. It just means you wont be getting a good fill. After you have acquired your scuba tank, the next item you will need is a Fill station, the fill station attaches to the valve on your scuba tank, and aids the transfer of air coming from your scuba tank, going into your HPA tank. That is pretty much it. Before even buying a scuba tank, make sure you have a way to fill it when you run out of air, some places require a C-card, or divers certification. Just make sure you can get your scuba tanks filled before even buying one. Please keep in mind that only certified techs should be conducting air fills for high pressure air systems. Please make sure you know what you are doing before you even attempt to fill your tank *I am not liable or either is www.pbreview.com if something happens to go wrong. Fill at your own risk.
  • HPA, N2, & Compressed Air... Whats the difference?

    For the use of paintball, they are all considered the same thing. Both N2 and Compressed air are the primary air sources used in a High Pressure Air System (HPA)
  • 3000psi/4500psi HPA tanks

    The difference? capacity... the 4500 psi tank holds 1500psi more! because 4.5k tanks have to hold a larger volume of air, these tanks must also be constructed to hold more air(larger tanks) The ability to get a full fill (4500psi) is a bit hard to achieve. Most common scuba tanks are rated for not much more then 3000psi. There are bulk tanks that can hold enough pressure to fill 4500psi tanks, but they are costly, and a lot larger to lug around in the back of your truck. Shops or fields often use booster, or large capacity air compressors that are capable of filling those 4.5kpsi tanks.

    3000psi tanks are often a lot cheaper then their 4500psi counterparts but don't hold as much air. If you don't go though that much paint then it's not really a big deal. Getting a 3kpsi tank is inexpensive and may suit your needs just right. There are various sizes all ranging from 68ci up to 114ci in both 3k, and 4.5kpsi pressure ranges.

    Here are several thinks you might want to consider when you are looking for a new tank

    *First figure out how much paint you go through. buying a tank that will five you enough air to shoot all of your paint you can carry in a single game is pretty much ideal. You don't want to have to worry about running out of air on the field. You can always refill before the next game. If your field doesn't have a set rate for all day air, then it can be costly to fill after every game, and then perhaps you should go for a larger tank that will last you several games.

    *Filling availability? Does your field have compressed air or n2 air fills? Can your field fill to 4500psi? It's kind of pointless to buy a 4500psi system if your field cant even offer 4500psi air fills. otherwise your better off saving your money and sticking with a 3k tank.

    *Fiber wrapped, if you have the money buy it. fiber wrapped tanks are lighter and it'll make your paintball experience on the field much more comfortable. And don't forget to buy a tank cover for your investment.
  • Buying a HPA tank, what size should I get? (Price VS Size)

    Recently quite a few people have been asking this question, and since it has not been addressed in the FAQ... *ala peanut butter and jelly!* here it is! HPA obviously has a performance advantage over co2 no matter how you look at it. What has already been clarified is that you get more shots out of a co2 tank for the price. None the less, performance wise HPA is much better to use on your marker, electronic or not it's a good investment.

    What do we know? We know that HPA tanks are expensive, sad but true solution... Get a job you bum! but seriously I always see people who first make the venture into HPA buy the smallest cheapest tank out there... Don't be cheap, get a tank that will provide you with more then enough air to last one game, you don't want to be running out of air in the middle of a game. And if you are cheap, i don't think you want to be paying for air fills after every game. A tank large enough to accommodate a few games is even more ideal. a bit more expensive yes, but in the long run a much better investment. Do you plan on upgrading to a better marker in the future. I can assure you that if you plan on playing paintball for quite sometime you'll be shooting much more paint then what you shoot now, a 47ci tank will not cut it. and buying a new tank after every marker upgrade can be even more costly then it needs to be.
  • What's Output Pressure mean?

    High Pressure Air systems are available in various output pressures. the term "output pressure" refers to the amount of pressure (measured in PSI) exiting your tank. Some tanks are available in preset & adjustable versions. Adjustable versions as already explained, feature an adjustable output pressure which the user can set to his/her needs. Preset tanks, as already explained are not adjustable, and feature a single fixed output pressure. These vary from a low output about 450psi (pressures may vary from manufacturer to manufacturer) and high output, 850psi or so.

    It's best to choose your preset tank according to your own marker's operating pressure. Do not purchase a low output preset tank, for a spyder which is a HP (high pressure) marker. And it's a bit more ideal to purchase a Low output tank for a low pressure marker. A low pressure marker will still function operating off of a high output tank, but a HP marker will not operate correctly off a LP tank. Make sure you choose the right tank.
  • Carbon Fiber VS Steel? which one is for me?

    The basics... Carbon Fiber tanks are built to be lightweight compared to their steel counterparts there is a noticable difference in weight. It's made of a composite shell wrapped by layers of carbon fiber skin. Considering how much pressure carbon fiber tanks can hold the material is very strong, and is used in various applications other then paintball. A steel tank is physically more durable then CF (carbon fiber). Scratch a steel tank, no bid deal. Scratch a fiber wrapped tank, and you run the risk of not passing your next hydrostatic test, or even worse. With that note extra care must be taken when using a fiber wrapped tank (*Please buy a tank cover) buying larger tanks is not so much of a physical burden on the field now as it used to be. There is a minimal sacrifice of agility as compared to using the pre fiber wrapped High Pressure Air systems. It's obviously much more comfortable to have on the field, at the expense of a higher cost. The majority of experienced / hardcore players use fiber wrapped systems for those very reasons. As air transfers from your bulk tank or compressor to your paintball high pressure air tank, this transfer results in heat that is why your tank gets a little warm when you get your tank filled. heated air is expanded air, as the tank cools down the air in your tank contracts, thus you notice a slight loss in air pressure. Steel tanks tend to heat up faster, getting hotter... and therefore more cooling is needed, and more pressure is lost. fiber wrapped tanks cool down too, but dont heat up as much as steel tanks to begin with so the loss in pressure is minimal compared to steel tanks.
