This product is a high-quality fully-wrapped carbon fiber composite cylinder, featuring a high-strength, corrosion-resistant, lightweight aluminum alloy liner, wrapped with multiple layers of carbon fiber and glass fiber, and finished with an epoxy resin protective coating. Its scientifically designed structure offers excellent pressure resistance, high-temperature tolerance, and flame retardancy, making it the core air source component of SCBA systems.
tructural Composition
The cylinder consists of four layers from inner to outer:
- Liner Layer: High-strength aluminum alloy, corrosion-treated, lightweight and durable.
- Carbon Fiber Layer: Fully-wrapped multi-layer carbon fiber providing exceptional tensile strength and pressure resistance.
- Glass Fiber Layer: Outer glass fiber wrapping enhancing high-temperature resistance and impact protection.
- Epoxy Resin Protective Coating: Surface coating protecting internal structure and improving durability.

1. Multi-Layer Composite Structure: Aluminum liner + carbon/glass fiber wrapping + epoxy coating—four layers of protection ensuring high strength and long service life.
2. Lightweight Design: Aluminum liner significantly reduces weight while carbon fiber enhances structural strength, making the cylinder easy to carry.
3. High-Pressure Capability: Rated at 30 MPa working pressure, hydrostatically tested to 50 MPa, with burst pressure ≥102 MPa, providing ample safety margin.
4. Luminescent Markings: Cylinder body features luminescent markings that glow in dark environments for easy identification under low-light conditions.
5. Protective Cover: Comes standard with a cylinder protective cover to absorb impacts and prevent scratches, extending service life.
6. Safety Certification: Accompanied by a safety performance inspection certificate, ensuring traceable quality and reliable use.
7. Hoop Markings: Ring-shaped markings on the cylinder body clearly indicate water capacity for quick identification.
Widely used in firefighting and rescue, petrochemical industry, industrial safety, mine rescue, shipbuilding, and other fields, particularly suitable for high-risk operational environments requiring extended respiratory protection.
