The Inflatable Life Jacket CO2 Cylinder is a key gas storage component designed for automatic or manually inflatable life jackets. It rapidly releases compressed, high-purity carbon dioxide to power the life jacket, ensuring full inflatability within seconds in the event of an emergency drowning, ensuring adequate buoyancy and safety for the wearer.
Product Features
1. High-Pressure Gas Storage Design
The cylinder is filled with high-purity carbon dioxide at a standard pressure of 55–60 bar (at 25°C). Upon release, it instantly generates sufficient gas volume (approximately 15–33 liters) to fully inflate the life jacket within 1–3 seconds, ensuring rapid life support in emergency situations.
2. Corrosion-Resistant and Robust Material
Made of Q235 carbon steel or 304 stainless steel, with a nickel or zinc coating for rust resistance, it boasts a tensile strength of ≥450 MPa. The cylinder has been hydrostatically tested to a pressure of ≥20 MPa, ensuring long-term leakage and rust resistance in high-temperature and seawater environments.
3. High-Precision Airtightness Testing
Each cylinder undergoes 100% airtightness testing and helium permeation testing before shipment to ensure zero leaks. The cylinder seal utilizes laser welding or mechanical sealing, ensuring a reliable seal that exceeds industry standards.
4. Replaceable Structure
The threaded connection design facilitates replacement and maintenance, allowing users to replace CO₂ cylinders without specialized tools, making it suitable for regular inspection and reuse of life jackets.
5. Environmentally Safe Gas
The filling gas is high-purity, food-grade carbon dioxide (≥99.5% purity), which is non-toxic, non-flammable, and harmless to humans and the marine environment.
Applications
1. Marine Navigation and Ship Lifesaving Equipment
Used in inflatable life jacket systems on commercial vessels, fishing boats, yachts, patrol boats, and other vessels, ensuring rapid buoyancy for those who fall into the water.
2. Water Sports and Leisure Fishing
For use with automatic or manual life jackets in water activities such as kayaking, sailing, surfing, and fishing, these life jackets provide safety.
3. Marine Engineering and Offshore Operations
Suitable for construction workers on offshore platforms and ports, as well as marine transportation and energy equipment maintenance personnel, providing professional drowning prevention and rescue support.
4. Military and Police and Emergency Rescue Equipment
Widely used in personal buoyancy systems for coast guard, maritime, and emergency rescue units, ensuring immediate response in complex environments.
5. Spare Parts for Travel and Shipping Companies
As a key replacement component for inflatable life jackets, CO₂ cylinders are in high demand on various tourist vessels, ferries, and yacht clubs.
6. Diving and Specialty Gas Applications
Some models can also be used for other small inflatable devices, such as emergency floats, buoys, flotation balls, or airbags.
Maintenance and Cleaning
1. Storage Environment
Store cylinders in a cool, dry, and well-ventilated area, away from high temperatures and direct sunlight. The recommended ambient temperature is 5–30°C and the humidity is below 65% RH.
2. Regular Inspection
Inspect cylinders every 6–12 months for rust, corrosion, dents, or leaks. If the cylinder is damaged or weighs less than the nominal value, replace it immediately.
3. Avoid Moisture and Impact
Do not expose cylinders to seawater or moisture for extended periods. Do not hit or drop them to avoid damaging the internal structure.
4. Cleaning
Surface stains can be wiped with a dry cloth. Do not use strong acid or alkaline cleaners. If the surface coating is damaged, spray with anti-rust oil to extend the life.
5. Replacement Cycle
According to international standards (ISO12402), CO2 cylinders are recommended to be replaced every two years of use or exposure. Even if they are not activated, they should be replaced regularly to ensure performance.
FAQs
Q1: How do I choose the right cylinder capacity?
A1: Choose based on the life jacket’s buoyancy rating. Adult self-inflating life jackets generally use 33g cylinders, while children’s or lightweight life jackets can use 16g or 24g cylinders.
Q2: Are the cylinder connections universal?
A2: International standard threads (such as M16×1.5 or 1/2-20 UNF) are typically used, but it is recommended to confirm the matching specifications based on the life jacket brand and model.
Q3: What is the lifespan of the cylinder?
A3: When not in use, it can be stored for 3–5 years, but it is recommended to replace it every 2 years to ensure airtightness.
Q4: Can it be shipped by air or courier?
A4: Yes, it is a non-flammable and non-explosive gas product and complies with international transportation safety standards (UN1013).
Q5: Are the cylinders quality certified?
A5: They are ISO12402, CE, RoHS, and other certifications, and some models meet U.S. Coast Guard (USCG) standards.
Q6: Can gas cylinders be stored in direct sunlight or high temperatures?
A6: Not recommended. Temperatures exceeding 50°C (50°C) can cause internal pressure to rise, posing a safety risk.
Q7: Do you support OEM/ODM?
A7: We support OEM/ODM services, including custom specifications, logo printing, packaging design, and bulk private labeling.
