    Hello,

         I am just starting with air rifles.  I don't have any equipment, yet, but am working on it.

         I have decided that the best thing that will work for me will be to have a carbon fiber tank that I fill at home and then take to the range with me.

         I have been looking at the Ninja 68/4500 tank   The gun I am looking at is the Air Arms T200.  I am guessing that the tank should be large enough to last me a couple hundred shots, or so, but maybe more.   Is this a good size tank or should I get a bigger one?

         The tank is listed as 4500 PSI so I assume that means that the tank can hold 4500psi.

         But the regulator that comes with it, says it is adjustable with Shims to 800psi.  Does this mean that I could only get 800psi into my gun?  If so, this won't work, because I thought the gun needed to be charged to a lot higher pressure.

        They make a 4500psi regulator, but it doesn't seem to be included.  Is this the regulator that I need?

        Is the Ninja tank a good value or would you recommend something else?

    Thank you for your help.

    Have a look at a umarex gauntlet and it will give you a better idea on ninja bottle. What you are looking at is only bigger. For filling a pcp, you won't need a regulated bottle.

    Ninja is a nice brand along with others and bigger bottles mean more fills. 4500psi rating mean you can fill a tank upto 4500.

    Use the calculator link above and figure how many fills you can have. I think t200 is 2900psi max fill.

    Good luck.

    thats not a tank that is normally used for filling a pcp, as theres no fill hose/gauge/

    its a regulated tank designed for use with co2/pcp/paintball guns 

     

    if youre looking for a small fill tank look at the benjamin pcp fill system.

    or airtanksforsale.com      joe b can tell you all you need to know about tanks.

     

    also, how do you plan to fill the tank at home?

    You are looking at Paintball 68 cubic inch tank. Yes it is rated for 4500 psi, but it is regulated for Paintball gun – 800 psi. It is relatively easy to put some shims or stoppers to crank that limit, but i don't know, if you want to mess with that. Appropriate regulator cost way more than $100 and it is not worth for such a small tank.

    If you looking for cheap tank, look at ebay for SCBA carbon firefighter breathing tanks. You can get one with current hydro for around $100-130 

    Technically carbon tanks have expiration date – 15 years from production date. But looks like more and more states expanding that time to 30 years. Each tank must have valid Hydro test. Hydro is good for 5 years, after that you have to retest at the local dive or fire extinguisher shop. It usually cost $30-50 and you are good for another 5 years

    Meaningful tank is at least 40-60 cubic feet not cubic inches

    Or they have minutes on the tanks 30 minutes – (44 c/ft), 45 minutes -(66 c/ft), 60 minutes – (88 c/ft)

    Since you are going to shoot an Air Arms T200 you could easily get away with a regular scuba tank (like the kind scuba divers use).  Find a used scuba tank on Craig's Linst for $50-$75 (make sure it is current on hydro inspections) and then buy the hose/gauge for a scuba tank.  You only need to fill a T200 to 2600-2700 psi and a T200 gets 120 shots per fill.  A regular scuba tank would fIt your needs fine and plenty more fill options than a 4500 tank.

    Brazo makes a good point. People got by with scuba tanks for years before hand pumps were available even.

    Used a 80cf aluminum tank for a decade. Has a Faber 110cf 3,450psi tank and that actually had SO much volume it worked out well.   The last time I talked to a scuba shop ( 3yrs ago in TN) they had a use in hydro 3,000 aluminum tank for $100.00 and 10 free ( $12.00 each if you catch the wrong person & $5 if the owner) refills.
