What volume carbon fiber tank do you prefer?

Hello, friend, may I know your email, shall we talk about the 20L?

Comparison between 6.8L and 20L
 
I agree. The cheapest I’ve seen a 12 liter was just over $400. For the house I have the 9. Also a 6.8 and 3 liter.
If I did it over it would be the 12 on a dolly like I have my 9 in the cellar . The 6.8 for the range. If someone was
worried about dimensions the 12 liter is only about an inch each way bigger.View attachment 541968

The same styles to you, would you like some rubber protectors?

Is the following statement correct?

The cylinder has a water volume of 550 cubic feet and an air volume of 2430 liters/85.8 cubic feet.
Based on experience, a 2L cylinder will fill a small 280cc cylinder 6 times as much, and it takes about 5-15 seconds to fill it.
A small 300cc cylinder has an air volume of 81L and a 2L cylinder has an air volume of 544L so that 9L will inflate it 30 times.
