air tank cost

[bwilson6561]

What is the manufacturing cost for a 0.75L air tank rated at 150 psi and 3000 psi respectively? (If 5000 of each is to be produced)?

Will the 3000 psi tank be a lot more expensive?

An approximate ball park guess would be preferred. Thanks

No approximate numbers, but the 3000 will be a lot more expensive. The 150 PSi could be almost paper thin (a 1 L pop bottle might come close to satisfying the requirement) while the 3,000 PSI would be 1/4" or 3/8" thick or so, depending geometry. I guess you would weld them up out of pipe pretty handily.
