Q1: How do I inflate it?

The best option is to inflate the system using a high-pressure air compressor with an 8mm standard connector. Using a high-pressure manual pump may require more than 800 cycles to reach 3000 psi.

Q2: What should I do if there is an air leak?

Air leakage will only occur if there is incorrect assembly or damaged seal. You can check this by following the inspection steps in the instruction manual and replace the corresponding parts.You can also contact after-sales support directly.

Q3: How long can it provide for underwater breathing?

At a depth of 10 feet, an adult can breathe for 5-10 minutes. Very relaxed, almost no movement: approximately 8-10 minutes. Normal slow swimming: approximately 5-7 minutes. Vigorous or strenuous movement: approximately 3-5 minutes.

Q4: Can beginners or non-certified users use this tank?

No. This product is intended for certified scuba divers only. Proper training and knowledge of underwater breathing equipment are required to use this tank safely.

Q5: Has it been DOT certified?

Yes, all UNAROWHALS diving cylinders have passed DOT certification before they are allowed to be sold.
