Safety starts
long before
you enter
the water.

OXSEA documentation specifies a 6061 aluminum body. This material combines mechanical strength with low weight. Tank quality also depends on manufacturing, testing and maintenance. Aluminum is not immune to corrosion: rinsing, drying and inspections remain essential, especially after use in salt water.

The stated working pressure for OXSEA tanks is 200 bar. Always check the markings and user manual for your model, as well as the compatibility of your refill equipment. A pressure used on a test bench is never a filling instruction. Do not exceed the permitted pressure, and monitor refilling according to the manufacturer’s procedure.

No. The 200 bar figure is the storage pressure inside a full tank, not the pressure of air delivered directly to your mouth. The regulator reduces this pressure to supply air at a pressure appropriate to the surrounding water. Proper operation and maintenance are therefore essential. Difficult breathing or abnormal airflow requires an inspection before the equipment is used again.

A leak check looks for leaks. A hydrostatic test subjects the tank body to pressurized water in a dedicated facility to check its behavior under a defined protocol. These checks address different questions and complement each other. They replace neither inspecting the condition of your equipment before use nor the periodic checks applicable to your tank.

Yes, a rupture is possible: compressed air stores energy. Design, testing, respecting the permitted pressure and maintenance help prevent this risk. Never exceed the specified pressure, and protect the tank from impacts and high heat. If there is any damage, corrosion or leak, keep it out of service until it has been inspected. No device can guarantee zero risk.

The disc is a protective device included in the equipment’s design; it does not make a tank risk-free. It does not allow you to exceed the permitted pressure or ignore an impact, leak or overheating. Do not modify it. If something is wrong, stop using the equipment and ask support for advice. Never work on pressurized equipment.

OXSEA states that every tank is individually checked before shipping. This does not mean that each unit undergoes every test illustrated. Production checks and qualification tests serve different purposes; the latter may involve samples or a configuration. To learn about the documented checks for your model, contact our team with your tank’s model and serial or batch number.

Identify your tank’s model, markings and serial or batch number. You can ask OXSEA for the user manual and compliance documents for that reference. A standard or declaration must be linked to the product it covers: a test photograph or logo is not enough to establish compliance across an entire range.

No. OXSEA tanks are designed to be accessible to everyone, with no training required. Before first use, read your model’s user manual and watch its tutorials: assembly, checks, refilling and maintenance. Taking care of your gear remains essential, even with a small tank and close to the surface.

Follow the most restrictive limit set by your exact model’s user manual and the conditions of the outing. Tank capacity in liters or stated air time does not define an authorized depth. Shallow water does not rule out pressure-related injuries. If your model’s limit is unclear, have OXSEA confirm it before entering the water.

As you ascend, pressure decreases and the air breathed underwater expands. Holding your breath can cause a serious lung injury, even close to the surface. Breathe normally, never hold your breath and follow the ascent instructions in your user manual. This essential habit must be understood and applied on every dive.

Advertised air times are estimates: up to 8 minutes for OX500, 15 minutes for OX1000 and 25 minutes for OX2000. Depth, exertion, breathing and conditions affect consumption. Plan your outing with an air reserve and check the pressure gauge regularly. Never wait until the advertised time is up or the air runs out to arrange your return.

No. Prepare to dive with a buddy. Agree on limits, signals and assistance arrangements before entering the water. Someone staying on the beach does not replace a buddy who can help. Choose conditions suited to your experience, and cancel the outing if visibility, current or your condition make it unsafe to proceed.

Yes. Breathing underwater places demands on the body that may be incompatible with certain health conditions or medications. If you are unsure of your fitness, consult a physician experienced in dive medicine before use. Also follow the age requirements in the user manual. Do not enter the water if you do not feel fit to dive.

No. OXSEA tanks are designed for compressed breathing air. Do not use pure oxygen or a gas mixture that is not approved for your equipment. A bicycle pump or workshop compressor is unsuitable: reaching a pressure does not guarantee breathing-air quality. The equipment, filtration and refill procedure must all be appropriate for this use.

In the current range, the OXSEA manual pump is intended for the OX500. The mini compressor is suitable for the OX500 and OX1000. The Power refills all three models and is the compressor option specified for the OX2000. Check the fittings and instructions for your version. Follow the prescribed pressure, operating cycles, rest periods and maintenance in the user manuals.

Use a system designed for breathing air, with the specified filtration maintained according to its manual. Position the intake in clean air, away from exhaust, fumes and chemicals. A filter does not make every atmosphere acceptable. Follow filter replacement intervals and maintenance procedures; the absence of an odor alone does not establish that the air is safe.

Before use, check the overall condition, fittings, hoses, pressure gauge and air reserve according to the manual. After the outing, follow the fresh-water rinsing and drying procedure for your model, without letting water enter the system. Store the equipment away from heat and impacts. These everyday steps complement inspections; they do not replace them.

Requirements depend on the model, its markings, its history and the rules in the country of use. Consult the user manual and have a qualified professional determine the necessary inspections or retests. Do not apply an interval found for a different tank. An impact, exposure to high heat or a defect may require an inspection before the usual due date.

Stop using and refilling the equipment. A leak, visible corrosion, deformation, an unreliable gauge or an impact calls for technical advice before returning it to service. Do not try to tighten or dismantle a pressurized fitting. Send support the model, circumstances and photos, then follow their instructions for inspection and, if needed, transport.

Ask your airline about its transport conditions and check security rules at every stage of your journey. Acceptance varies by carrier and destination. A pressurized tank must not travel by air. Its preparation and any disassembly must follow your model’s procedure, after complete depressurization. Obtain these instructions before departure; never dismantle pressurized equipment.

No: allow a dive-free interval before flying or traveling to altitude. Its length depends on dive profiles and repeated dives; using a mini tank does not remove this precaution. Plan your trip following DAN recommendations. If you have symptoms after diving, seek emergency assistance and urgent medical advice before any travel.

If you experience unusual symptoms during or after a dive, contact local emergency services immediately and tell them that a dive took place. Give your location, symptoms and any available dive information. Do not wait for a support reply before seeking medical help. For a nonemergency equipment fault, keep the equipment out of service and contact OXSEA support.
