Product Capacity: 2 liters / 20Cu ft capacity, Product Neck Thread: M18x1.5-6H thread. Product Pressure: 30mpa / 300bar / 4500psi working pressure, 50Mpa hydrostatic test pressure, 102Mpa minimum burst pressure Product Certification: CE / EN approved (Not DOT), Inspection cycle: 3Yr, Service life: 15Yr. Product Testing Performance: One of the safety tests is the hydrostatic test pressure, for carbon fiber cylinders, it can reach 50Mpa. The other is the minimum burst pressure, which can reach 102Mpa for carbon fiber cylinders, can hold more gas under the same volume conditions. Product Advantage: Carbon fiber composite air cylinder is a new material cylinder developed in recent years. Compared with the traditional steel cylinders, the weight is reduced by 70%, the corrosion resistance is strong, there is no magnetic property, the performance is stable, and the inner surface is specially treated to ensure that the holding gas is clean and has no odor, long service life (The service life is 15 years).
