The hybrid mask is great.

Already used and always satisfied. Perfect for snorkeling and short dives from the surface to explore or follow a fish. The automatic switch from the OXAIR mask’s snorkel to the tank’s air is amazing.

Works perfectly

I tested it in our pool, and it works. I filled it with my compressor. You need to get used to the breathing, but it’s a quick learning curve. Runtime is 5 to 8 minutes, depending on the person. Can’t wait to try it in Hawaii next month.

Good experience

My second mini tank. The first one was defective: a permanent leak, and it ended up on a shelf. The OXSEA one is the complete opposite: six uses in a few months, no leaks, no issues. I fill it with my compressor and get about 8 minutes. I couldn’t be more satisfied. I would buy again.

3rd purchase

This is not my first purchase. The whole family has several. Enough said. Perfect for snorkeling and having a backup air supply for quick dives. Easy to use, no issues. My son loves it with the full-face mask. Durable equipment.

No issues.

Easy setup. Fills in about 10 minutes using the compressor. Runtime of 15 to 20 minutes, depending on air flow and your breathing. Easy to use, reliable equipment. Excellent purchase, I recommend it.

You asked

How long can I breathe underwater with an OXSEA cylinder?

The duration depends on your breathing and depth. On average, the OX500/OX500PLUS provides up to 8 minutes of autonomy and up to 15 minutes for the OX1000. Ideal for freeing a stuck anchor, checking a propeller, or exploring the seabed near the boat.

Are OXSEA cylinders safe and compliant?

Yes. All our cylinders comply with CE EN250 standard, the European benchmark for diving equipment. Each cylinder is individually tested before shipment to ensure maximum safety.

How do I recharge my OXSEA cylinder?

You can recharge it in three ways:

  • With the manual pump (for OX500 cylinders only)
  • With the OXSEA 12V mini compressor
  • Using a refilling station to transfer air from a standard diving cylinder to the OXSEA mini cylinder

How long does it take to recharge an OXSEA cylinder?

Average recharge times:
Manual pump:
OX500 → approximately 15 minutes
OX1000 → approximately 30 minutes (not recommended)
Yoke or DIN filling station:
Filling time → approximately 1 minute
12V Mini-compressor:
OX500 → approximately 12 minutes
OX1000 → approximately 20 minutes

Can I travel by plane with an OXSEA mini-cylinder?

Yes, it is possible to travel by plane with an OXSEA cylinder, provided certain safety rules are followed:
Before the flight:
The cylinder must be completely empty.
The valve (regulator) must be open or disconnected from the tank.
It is mandatory to declare the cylinder during check-in or boarding.
Please note:
Some airlines require the valve to be completely disassembled. The operation is simple: just unscrew the upper part of the tank by hand.
Tip:
Before traveling, always check your airline’s policy, as requirements may vary from one carrier to another.
