Description
Pressure Is Not a Risk. Unverified Pressure Is.
Depth has a way of making engineering honest. At thirty metres there are no clever workarounds and no forgiving margins: the vessel strapped to your back is either built to hold 300 bar of compressed air without argument, or it is not. That is why the specification sheet on a breathing-air cylinder matters more than the badge on the shoulder straps. A tank is not accommodation for a dive; it is the entire duration of the dive, distilled into a few litres of volume and a pressure rating that you will trust with your life on every descent.
The Acecare carbon fibre cylinder is built around that trust. A seamless, fully wrapped vessel with an imported carbon fibre liner carries a 30MPa / 300 bar / 4500 psi working pressure, which is the standard that opens the widest range of fills at dive centres and fire-service supply points. Three capacities cover three different jobs: the 3L bottle for short, technical or bailout duty; the 6.8L for recreational dives and rebreather off-board feed; and the 9L for longer bottom times and for SCBA breathing-air packs. Each size is dimensioned honestly — 446mm, 528mm and 558mm in length, 114mm, 157mm and 174mm in diameter, and 2.1kg, 3.8kg and 4.9kg in weight before the valve — so the rig can be planned rather than guessed.
The hardware details are the ones that decide whether a cylinder becomes equipment or a liability. The M18 × 1.5 neck threading takes the standard valve and fill-station fittings used across the industry, and each option ships as tank, valve and fill station so the set is complete rather than almost complete. A stainless oil-filled gauge reads the fill without the needle flutter that plagues cheap analogue hardware, and the CE certification plus fifteen-year service life means the cylinder is documented for long-term ownership rather than a single season. Detailed parameters are permanently marked on the body of the tank, so the specification travels with the vessel into any fill station in any country.
The dive begins when you trust the cylinder. Everything after that is swimming.

Where This Tool Belongs
In diving, the 3L bottle is the one that goes where the plan changes — bailout for technical dives, a pony bottle for solo redundancy, or the compact air supply for a shallow inspection where a full set would be overkill. The 6.8L is the workhorse of recreational diving and off-board rebreather feed, small enough to travel and large enough to matter. The 9L suits longer bottom times, deeper profiles and the divers who simply prefer fewer fills. Outside the water, the same vessel serves fire-safety and SCBA duty, where a lightweight 300 bar cylinder is the difference between a wearer who can work in full kit and one who cannot. Because the set arrives with valve and fill station, it is also the practical choice for dive shops, rental fleets and training centres building capacity — and the fifteen-year documented life means it is an asset that depreciates slowly rather than a consumable that expires. Always fill with breathable air from a maintained compressor and observe the inspection intervals required in your jurisdiction.
Frequently Asked Questions
Q: Which capacity should I choose?
Choose 3L for bailout, technical or short inspection duty, 6.8L as an all-round recreational and rebreather-feed size, and 9L for longer dives, deeper profiles or SCBA breathing-air packs. Weight and diameter scale with capacity.
Q: What pressure do dive centres fill to?
This cylinder is rated to 30MPa / 300 bar / 4500 psi, which is the high-pressure standard accepted at most technical fill stations. Fill only to the pressure marked on the tank and never exceed it.
Q: Is the valve and fill station included?
Yes. Each option is supplied as tank plus valve plus fill station, so the set is usable on arrival. Verify the selected variant before ordering to confirm which capacity and configuration you are receiving.
Q: Can it be used for firefighting or SCBA work?
Yes. The manufacturer lists fire safety, firefighting and SCBA use alongside scuba diving. Any breathing-air application must follow local certification and inspection rules.
Q: How long does the cylinder last?
A full 15-year service life is documented with CE certification, subject to the periodic inspection regime in your country. Service dates and parameters are marked on the tank body.
Q: What is the thread size?
The neck is threaded M18 × 1.5, which matches the standard valve and fill-station fittings used across the industry.
