Reference PM
Four high-pressure cylinders, a built-in filter and a gauge to follow the fill. It connects to the OX500 and the OX500Plus with a high-pressure hose.
It is not compatible with the OX1000: for the one-litre tank, use the mini compressor or the transfer station.
Set the pump on a stable surface, connect the high-pressure hose to the tank, then pump at a steady pace. Allow around 20 minutes for 0.5 litre.
Take a break if the pump gets hot. The pump's gauge shows the pressure: stop at 200 bar.
The pump filter needs changing regularly: it protects the air you breathe.

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.
