Product Capacity:9 liters capacity, Product Neck Thread: M18x1.5-6H thread. Product Pressure:30mpa / 300bar / 4500psi working pressure, 50Mpa hydrostatic test pressure, 102Mpa minimum burst pressure Product Structure: Using high-quality raw material 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 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 Application: Loading gas, Emergency escape, Fire breathing, Underwater breathing, 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.
