Cylinder design

1

Finishing layer – glass fiber finishing layer gives appropriate protection for carbon from external mechanical impacts.

2

Composite layer – carbon fiber reinforcing layer keeps high up to NO LIMIT bar working pressure and ensure the best weight efficiency of cylinder.

3

Steel liner – thin wall 0,5 mm stainless steel liner provides cylinder reliability, safety and lower weight.

Aggressive gases resistance

According to ISO11114-1 the aluminum in not allowed for certain range of products,
but stainless steel option perfectly fit with this regulation.
