    Never seen them before, it says first test date 2007 so that will have been made (if SCBA) in 2002 meaning the design is 16 years old!

    It obviously never took off then!

    Yes of course as filling is only regulated for commercial outlets, you can fill your own cylinder forever, however not sure if your house insurance would be valid if there was an issue!

    Swedish company Interspiro make unlimited CB cylinders Spirolite with 200 000 cycles = 800 years Lifetime !!! The 6.7 Litre cylinder, here, packs 1810 litres of air, which lasts about forty-five minutes of average duty, yet it is hardly bigger than a '30 minute' steel cylinder and just over half its weight!

    No sir,

    These cylinders are made through a different technology. 

    These are not one piece rather these are made of three pieces. Bottom is separate piece that is screwed into the cylinder body and again the top area is also screwed into the cylinder body.

    These are bigger in size but are light weight.

    Built quality looks amazing. 

    I wonder that how they write unlimited life on these cylinders. 

    What will be the price of a new one like this?

    Regards,

    I do not believe they have a DOT Special Permit number.  Hence they would not be sold or allowed in the USA.  At least to be transported in commerce.  I may be wrong, but I would be surprised that it was truly a 3 piece design operating at this pressure.  The black caps on either end are most likely just protection to help protect the vulnerable domes from impacts.

    Yes those two rubber shields are just protectors but under those shield there are threads through which 3 cylinder parts have been screwed in to each other to make one complete cylinder

    Mark spot on, can’t transport and no reputable US based business would risk the liability of filling such a system without a DOT sticker.  Heck my local dive shot spun itself up into a complete tizzy over the LE sticker on my Air Venturi 66cuft tank. I ended up leaving it with them and sending them a bunch of extra info on the DOT Permit, my pouchsee order from Pyramyd, and an explanation of the LE Recertified program.

    I currently have an Interspiro. In Europe, no DOT, same exact tanks, ANY carbon fiber 4500psi tank has a 30 year life. DOT is BS. I'll be buying a Crosman compressor for around $600 & filling that tank until I die, which won't be from a 4500psi filled grenade. Don't listen to me, or let me tell you what's safe or not. I'm just saying I'm not going to expose my tank to pressures of 7-11K when hydro tested. Again, same tanks, 30 year life & I'll be dead of natural causes before that tank expires in 30 years.
