Crafted from 6061 aerospace aluminum, our tank is ultra-light—just a third the weight of steel—making it perfect for travel, beach dives, and spare air for deep diving.
Exceptional Strength-to-Weight Ratio: With a typical tensile strength exceeding 240 MPa(35,000 psi), it provides robust containment for your air.
Superior Corrosion Resistance: Withstands harsh saltwater environments, ensuring longevity and reliability.
High Fatigue Resistance: Engineered to endure repeated pressure cycles safely.
Stringent Compliance: Fully certified to meet or exceed DOT/ISO/TC 3AA high-pressure cylinder safety standards for complete peace of mind.
The 150-micron ultra-thick hard anodized layer(equivalent to 3 times the diameter of a human hair) designed for harsh marine environments provides triple professional-grade protection for aluminum alloy cylinders.
Never hurts to have a little backup breath, right? This 0.5L tank’s got your back when your main air’s calling it a day—compact, reliable, and cooler than your buddy’s safety sausage.
With DEDEPU’s balanced regulator, you get steady 1MPa airflow—even under 200MPa tank pressure. That means no surprises, just smooth, easy breaths underwater.
Auto vents at 4500–5000psi to prevent overfill—no babysitting needed, even on hot beach days.
Your DEDEPU mini tank isn't just for the water. Whether it's a backup for deep dives, a lifeline in fire evacuations, or even breaking a window underwater—it's got your back when things get serious.
Professional deep diving backup: meets EN250:2014 breathing air standard, 40 meters deep safe backup(need to be equipped with a standard regulator)
Emergency evacuation assistance: passed 200+ rapid charging and discharging tests by a third-party organization, meeting the basic performance of NFPA 1986 emergency breathing system
Extreme situation obstacle breaking: laboratory verified, with special impact accessories, it can generate≥2300N instantaneous impact force(safety warning: direct human contact is strictly prohibited)
Modular quick release of breathing valve and regulator (compliant with FAA 49 CFR §175.10)
Φ89×220mm cylindrical design, IATA tested to fit 99% of cabin luggage racks

The DEDEPU 0.5L mini scuba tank offers four convenient refilling methods, ensuring you're always ready for your next dive or emergency use. Designed for maximum flexibility and safety, each method has been carefully tested to meet industry standards.
Refill at certified dive shops—our tank is DOT-approved for safe and professional air fills. This method ensures the highest quality breathing air and compliance with all safety regulations.
Air purity meets rigorous breathing standards, pressure accuracy is certified, and all refill equipment undergoes regular professional maintenance.
A portable manual high-pressure pump lets you refill anywhere with no electricity—requires about 500-600 pumps for a full tank. Ideal for remote locations where traditional refill options aren't available.
Weighing only 3.5kg, the compact pump fits in any dive bag. No power sources required, making it perfect for wilderness diving, survival kits, or emergency situations.
Quickly and effortlessly refill your tank with a high-pressure electric pump in just 3-5 minutes. Designed for home or boat use where power sources are available.
Use only compressors specifically designed for mini diving cylinders (3000-4500 PSI range) with built-in moisture traps to ensure air quality.
Dramatically reduces refill time and effort, featuring auto-shutoff at full pressure. Perfect for frequent divers needing fast refills.
Use existing large cylinder resources via standard inflation conversion adapters (8mm interface). Easily transfer air from larger tanks to quickly fill your mini tank without any pumps.
Air transfer completes in about 15-20 seconds using a standard J-connector.
Ensure proper pressure equalization during transfer. Available adapter kits include pressure gauges and bleed valves for safety.
Regardless of the filling method: Ensure compressed air is dry, oil-free, non-contaminated and meets breathing air standards (ANSI/CEA Grade E or equivalent).
