Product Specification: 6.8L capacity, 20-30 MPa / 3000-4500 PSI service pressure, CE Approved ( Not DOT Approved ), M18x1.5 bottle screw thread size. Product Safety Performance Testing: 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 Structure: Using high-quality raw materials AL6061 aluminum alloy liner with full-wrapped carbon fiber and glass fiber winding, external surface treatment is epoxy coated, high strength features creep resistance, shock resistance and corrosion resistance. 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). Product Application: Loading gas, Emergency escape respirator, Fire breathing apparatus, Underwater breathing apparatus, Lifesaving of ships, Clean energy, Snorkeling diving breathing, PCP rifle and Paintball filling, Medical care and Mine emergency etc. Widely for fire-fighting, chemical industry, shipping, laboratory, mine, pertroleum, warehouse, factory and metallurgy, it can be used in various positive pressure breathing apparatus.
