DEDEPU D600 2.3L Mini Scuba Tank
The DEDEPU D600 2.3L is the highest-capacity mini scuba tank in the DEDEPU lineup, built for extended reef exploration, underwater maintenance, and demanding dive environments. Constructed from lightweight 6061 aerospace-grade aluminum, it delivers outstanding strength while weighing approximately one-third as much as steel. A multi-layer protective finish enhances corrosion and wear resistance for long-lasting durability in saltwater conditions.
The chrome-plated brass valve features a 5,000 PSI burst disc that automatically relieves excess pressure, providing an additional layer of overpressure protection. An extended luminous pressure gauge remains easy to read in low-light environments, including night dives, wrecks, and overhead settings. Certified to CE EN250 and U.S. DOT standards, the D600 comes as a complete diving kit, ready for reliable underwater performance.

Safety When It Truly Counts
Depth Ready
Designed for deeper and more demanding environments, it performs reliably where smaller cylinders are no longer enough—making it a true backup, not just a reassurance.
Extended Margin
More air means more decisions. The 2.3L capacity buys you time to stabilize breathing, solve problems underwater, and surface in control instead of in panic.
Work-Level Reliability
Whether for hull checks, underwater tasks, or serious exploration, this cylinder is built for repeated, real-world use—stable, predictable, and dependable when conditions are not ideal.
6061 Aviation Aluminum
Dive deeper,easier.Our premium 6061 aerospace-grade aluminum offers certified aviation strength in an ultralight package.Proven 67% lighter than steel,it reduces diver fatigue while delivering robust reliability.Certified for depths to 60 meters,it provides dependable backup air,backed by corrosion resistance and structural integrity testing.
Excellent durability, safe diving
The 150-micron hard anodized layer provides triple protection, blocking seawater erosion, resisting impact and friction with a hardness of HV500+, and bonding seamlessly with the cylinder to prevent peeling and extend service life.
Extendable Glow Gauge
Stay aware of your air with our extendable luminescent gauge—perfect for low visibility dives like wrecks or night dives, offering clear pressure readings at a glance.
Our engineering team has developed an advanced pressure relief principle, where a 5k explosion-proof valve compresses a 0.152mm copper membrane. When the tank limit is approached, the copper membrane will burst, releasing pressure from the small hole, preventing equipment from over-pressurizing during technical diving and long coral reef explorations.
Conserve every molecule of precious breathing gas with our hermetically sealed valve technology. This innovative system eliminates the micro-leaks common in conventional tanks, preserving your air supply between dive trips and ensuring your equipment is ready whenever adventure calls.
Built for Serious Conditions
Hull Work
Routine tasks under a boat often require focus rather than speed.The D600 2.3L scuba tank provides a steady air reserve that allows users to work calmly beneath the hull, complete inspections or light maintenance, and surface only when the task is finished.
Reef Exploration
For freedivers exploring coral reefs, the D600 2.3L scuba tank acts as a reliable support air source.It offers additional breathing time to observe marine life closely, recover between dives, and remain composed while navigating complex underwater environments.
Emergency Backup
Pair text with an image to focus on your chosen product, collection, or blog post. Add details on availability, style, or even provide a review.
Chromatic Elegance
Stand out with our vacuum-chromed regulator—its unique color finish resists saltwater corrosion and wear, combining bold looks with long-lasting durability for every dive.
How it works?
Dual-Stage Filtration
Compressed air enters through a precision filter, ensuring clean, high-quality air.
Stable Pressure
The constant-pressure chamber converts high-pressure air into a steady medium-pressure output.
Smooth Airflow
Regulated air flows through the medium-pressure tube to the breathing valve for stable, comfortable breathing.
Four Easy Ways to Refill
Dive shops, hand pumps, electric pumps, or tank transfers—choose the best refill method for your needs. Our 1L diving tank fits every solution.
Note: Using a high-pressure hand pump to inflate may take an hour, but of cource if you love fitness, it can also be used as a tool for exercise.
Dive Shop Refill
Refill at certified dive shops.Our DOT-approved cylinder can be safely filled by professionals, typically costing just $5–10 per refill.
Electric Compressor
Quickly and easily refill your tank with a high-pressure electric compressor. Filling the tank to 3,000 PSI takes approximately 56 minutes.
Refill Adapter
Use an 8mm scuba refill adapter to transfer air from a larger scuba tank. Filling the tank to 3,000 PSI takes approximately 75 seconds.
SAFETY NOTICE
BEST PRACTICESRegardless of the filling method:
✅Keep the inside of the cylinder dry.If you seawater enters,rinse with fresh water and dry completely.
✅Store long term with 5 MPa internal pressure.
✅After 2 years,have the cylinder inspected by a diving service center.
✅Do not exceed 4500PSI.A built-in burst disc provides overpressure protection.

FAQS
The price difference between the D600 and S3000 is significant. What explains it?
The D600 offers 4.6 times more capacity (2.3L vs 0.5L), a higher depth rating (40–50m vs 30m), and a chrome-plated brass valve instead of a standard aluminum one. It also comes as a full package with a luminous pressure gauge, dedicated backpack, inflation adapter, anti-fog mask, snorkel tube, neck ring, and carrying bag—10 items in total. Purchasing these accessories separately would cost significantly more. The D600 is built for heavy-duty and more technical diving use.
Is the 30–40 minutes usage time real?
This is an estimated value based on average lung capacity, shallow diving conditions (5–10 meters), and light activity. Air consumption increases significantly with depth—roughly doubling every 10 meters. Physical exertion can increase consumption by 3–5 times compared to resting, and cold water or stress will also speed up breathing. Always check the pressure gauge during use rather than relying solely on time estimates.
What is a rupture disc? What happens if it breaks?
The rupture disc is a built-in safety device that automatically releases excess pressure if the cylinder becomes overpressurized. If it ruptures, simply contact our customer support and we'll send you a replacement free of charge. It can be easily replaced by following our instructions.
How should it be stored when not in use for a long time?
Rinse the tank with fresh water and let it dry completely. Store it with about 50 bar (725 PSI) of pressure in a cool, dry place away from heat and pool chemicals. Check the pressure gauge every few months. If you notice a significant pressure drop, the valve may need servicing.
Can I take the D600 2.3L on a plane?
Yes,it can be taken on a plane after being completely disassembled and depressurized.Always check with your airplane for specific regulations before traveling.
How long does shipping take and is the packaging secure?
We ship worldwide (free shipping on orders over $99) to more than 50 countries. Delivery usually takes 7–14 business days. All orders are packed in a reinforced box with internal foam protection to secure the product during transit. We recommend checking the outer packaging for any major damage before signing for delivery.
