For diving equipment manufacturers, rescue suppliers and OEM manufacturers, a mini SCUBA tank is more than just a small air cylinder. Its value comes from being compact, portable and ready to support backup air, shallow diving, rescue equipment and surface-supplied air systems without adding the size, weight and inconvenience of a full size SCUBA or breathing air cylinder.
Mini SCUBA tanks are ideal when size is an issue
Sometimes a full sized cylinder is not the most practical solution for breathing air, which is why the lightweight, compact design of DCEC mini scuba tanks makes them ideal for supporting underwater activities, such as shallow diving and surface air supply systems. They can also be used as spare air, as backup air for scuba divers, for short duration underwater work, as rescue gear and in compact air kits for snorkeling or simply boat safety.
The range of available sizes gives businesses and manufacturers the freedom to choose a cylinder around their needs, with the DCEC standard mini SCUBA tank catalog including 22ci, 26ci, 30ci, 48ci and 62ci sizes, equivalent to water capacities ranging from 0.36 litres to 1 litre. For OEM suppliers, this presents a unique opportunity to select a purpose built, compact, lightweight tank that can be matched to the needs of your customers.

A6061 aluminum cylinders for rugged, corrosion resistant reliability
DCEC manufactures our mini SCUBA tanks from inclusion-free 6061 aluminum alloy, with all models rated to a working pressure of 3000 psi (207 bar). This gives equipment manufacturers a lightweight high-pressure cylinder that can be integrated into compact diving and safety systems without worrying about pressure limitations, corrosion or physical reliability.
Material choice matters when a high pressure cylinder needs to remain portable and lightweight. To ensure manufacturers can reduce equipment weight without giving up high-pressure performance DCEC uses 6061 aluminum alloy across its extensive range of mini scuba tanks. As well as this, the cylinders are precision machined, hydrostatically tested and use a standard ⅝-18UNF thread.
The full range is rated to the same 3000 psi (207 bar) working pressure, while different diameters and lengths make it easier to match the cylinder format to the application. In addition, both round bottom and flat base options are available. This gives manufacturers more choice when it comes to integrating the tanks into compact dive equipment, backup air systems or portable rescue kits.
OEM ready mini SCUBA tanks
For dive gear, rescue systems or private label equipment brands, the cylinder needs to fit the finished product, both visually and technically. DCEC offers mini SCUBA tanks for OEM and private label supply, meaning manufacturers can easily integrate the cylinders into their own finished products and have them supplied with branding that matches their product range. Additionally, cylinders can be delivered with standard valves pre-installed, leak tested and torqued to your specifications.
Branding can easily be incorporated directly onto the cylinder by silk screen printing, laser marking or applied label. Available finish options include standard glass black as well as custom colours on request. This gives manufacturers the option to use the tank to promote your products, with its finish, branding and configuration selected to fit the wider equipment range.
Testing and traceability for aluminum pressure cylinder compliance
Mini scuba tanks are high pressure cylinders, so testing and production control are very important. At DCEC, we manufacture our mini SCUBA tanks using ISO 9001 certified processes. Cylinder certification options include TPED PI marking for the EU and ISO 7866 for aluminum pressure cylinders, with DCEC also capable of providing additional markings depending on the intended region or application.
Each unit is traceable by batch and checked for hydrostatic integrity, dimensional accuracy and leak-proof performance. Hydrostatic testing is carried out to at least 1.5 times working pressure, and leak testing is performed after valve assembly when the valves are preinstalled.
Compact aluminum cylinders for different purposes
The main advantages of DCEC mini SCUBA tanks come from the combination of a compact format with the durability and high pressure performance required for pony bottles in professional diving applications, and self-rescuer and egress bottle air supplies for emergency requirements.
The 3000 psi aluminum cylinder can be used across a wide range of diving and safety applications. It is suitable for backup air systems, shallow diving equipment, portable rescue kits and surface supplied air systems, all while remaining lighter than many everyday laptops. Contact DCEC to discuss cylinder size, certification, finish, valve configuration and other requirements for your mini SCUBA tanks.
