    I just bought one of these 'life extended' tanks from PA yesterday for $400.  I wanted something bigger than what I already had, and this should fit the bill with 8 years of usable life left.  And comes complete with valve and fill whip.

    If you have a compressor any  SCBA tank in good physical shape for the lowest possible price will do. I've seen tanks without valves for as low as $35. I can get recertified valves for $25 if you happen to need one.

    The best deal for new air tank right now is Acecare 6.8L or 9L depends on your need, costing around $270~ including fill ports.

    When I bought it 4 days was the time it took to arrive it's insane, but do talk to the sale representative to find out time, stock etc.

    CAUTION, CAUTION, CAUTION:  These bottles have to be RECERTIFIED EVERY 5 YEARS!   That means that if you buy one with 8 years left of extended life, you may have to pay for requalification in 3 years!  To get the full 8 years you will definitely have to pay another $400+.  I contacted Digital Wave Corporation directly a few months ago to inquire about recertifying an expired bottle and was told that the cost is about $400 (I don't recall the exact cost) plus shipping to/from metro Denver.  They are selling recertified bottles for basically the price of recertification.  That makes these bottles essentially disposable. 

    Pyramid air is not making this clear unless you read the COMPLETE description.  They state that the cost is about the same as a hydro cost, but it is actually about $400 plus shipping.   Can anyone who has done a hydro let us know the cost?

    They have a link to the document DOT-SP-16320. READ SECTION 7-a-4.  It states: "Cylinders passing the MAE requalification may be marked "DOT-SP-16320" and authorized for an additional 5 years.  Cylinders with the DOT-SP-16320 marking must be successfully requalified once every 5 years using MAE in order to remain in service for a maximum service life of 30 years from the date of manufacture"  (emphasis added)

    The date of recertification is critical to know how many years are actually left before the next requalification is required.  Requalification includes an inspection of the external surface for damage.  (damage to the fiberglass wrap = failure)

    Thanks for the heads up. But I do work in a remote part of west Texas in the oils field so I am not always able to reply in a timely manner. 
     But thank you guys I for the info. I was ready to sell my impact bec of the high expenses for an air tank and the inconvenience of pumps. 
    I may still sell it but this at lest gives me something more to look at.

    Good to know you are taking in the information.  Thanks for the follow up. 

     

    I work graveyard and fully understand the work/play/post issue.  A small air cooled pump may be the ticket for you.  They are not heavy duty by any means, but they work well enough and don't need extra water tanks for cooling.

    GX CS2 or GX CS3 from Amazon.  I have the fancier CS3 model.  Direct pump to gun, no water and no oil.  If you need more info, just holla.  And thanks for.keeping the oil and natural gas flowing.  We all benefit from your hard work.

    Ok, more questions on air tanks.  Since I bought my Texan, my need for air has really increased, and I’m shocked at the tank prices.  I have a GX CS3, and it’s great, but I would like to shoot without filling after 1 or 2 shots sometimes. I notice my local dive shop will sell me a used 100 cf steel Scuba tank with valve for $250.  Other than the weight, why couldn’t I do that?  It says it comes with a valve, what do I need to add to be able to use it? Thanks.

    In my 20 years of experience with PCPs and trying every type of filling device and many compressors, my #1 piece of advice to anyone is never, underline never, waste your money on a steel diver tank as a source for filling your air rifle.   Carbon fiber tanks are 4 times lighter but hold 5 times the fill capacity of scuba tanks.  Carbon fiber tanks hold more fills because they pressurize to 4500 psi whereas steel scuba tanks only  hold 3,300 psi in rare instances.  So you're lugging around a larger, heavier tank that holds much fewer fills.  Dive shops and paintball shops charge the same for a 3,000 psi fill as a 4,500 psi fill in most instances.  Pay once, cry once. $250 for a steel tank is a total waste of money.   Been there done that.

    I have a 30 min tank and a 60 min tank … both bought from Ebay and have been great.  You can get them hydro tested for a few hundred bucks….. or you can look at a compressor and fill them yourself.  Yes there is some risk, but there is a risk on everything we do with this hobby.

    As far as air tanks, I went big-bought an industrial size 250 tank, had the local weld shop put 4500psi in it and got a fill station off of Amazon.  The tank has a CGA-347 valve on it and make sure the fill station nipple is a male cga-347.  Word of caution here, this tank is not portable by any means.  Its empty weight is 150# and 180# full.  The fill station is just an adapter between the tank valve and the gun.  It has a pressure gauge on it and a hose bleed valve.  when filling from the tank turn its valve extremely slow until gun is at its upper pressure.  If not very careful with this set up u could blow the seals out of the gun very easily.  This tank certified to 6750psi cost me $370.  I have a regulator on the way and that is where the big bucks come in at $542, but I will be able to set the delivery pressure and not worry about blowing the gun up.  This tank is 444 cubic foot displacement, 51" high and 9" in diameter.  It is the size of the larger welding bottles.  Holds enough air for hundreds of refills.  Later on I will get a portable bottle that I can fill from the larger on.  But for now, I have plenty of air to tune my guns right in the back yard without getting tennis elbow from the pump.

    I agree. I have the 9l acecare tank and it’s great.
