## Description

Mini Scuba Tank with Standard Constant Respiratory Volume Controller, 5-10 Minutes Usage Time, DOT/CE-EN250 Certified, 0.5L Capacity (3.5Cu Ft), Max Pressure 3000PSI

## Features

- COMPATIBILITY - When these tanks are used with a compatible diving mask, the snorkel mask absorbs air from the outside when it is on the surface, and when it is underwater, the tank air automatically fills the inside of the mask, allowing you to breathe freely through your nose and mouth. Whether snorkeling along vibrant coral reefs or shallow diving in tranquil lagoons, it will provide users with the flexibility to immerse themselves in different aquatic environments.
- CONVENIENCE - Mini scuba diving tanks provide convenience like no other. This underwater tank can hold 3.5 cuft of air at a pressure of 3000 psi, which can be used underwater for about 5-10 minutes. Eliminate the need for bulky dive equipment and extensive installation processes. With a mini diving tank, divers can quickly and easily access underwater exploration. Whether it's a snorkeling trip, a shallow dive or underwater photography, these small underwater tanks offer hassle-free diving experiences.
- Safety: Although underwater air tanks are smaller in size, they are designed with safety as a top priority. This diving tank is made of aviation aluminum and is equipped with reliable pressure gauges, valves and regulators while using a more stable constant pressure breathing valve to ensure proper operation and air supply during diving. They are rigorously tested and DOT certified to ensure the safety of divers. With the mini underwater tanks, divers can embark on underwater adventures with peace of mind.
- Usage: This cylinder requires assembly by yourself, there is no gas in it, so please make sure you have high pressure filling equipment before purchase. The cylinder interface has a multi-layer filtering device to prevent dust and impurities from entering the bottle, making the air in the bottle cleaner. The bottle head is equipped with a switch, which can freely control the gas inlet and outlet in the bottle to avoid accidental leakage.
- What you get: includes a 0.5L gas cylinder, a constant pressure breathing valve, a portable bag, a large bag, a diving adapter, a full face mask, a mask adapter and an anti-leak rope. We provide 24-hour online service and lifetime customer support if you have any questions.

## Questions & Answers

**Q: Q1: How long can this 0.5L mini scuba tank last underwater?**
A: When fully filled to 3000 PSI, the 0.5L scuba tank can provide up to 5-10 minutes of breathing air. Actual duration depends on dive depth, water conditions, and individual breathing rate. This tank is a backup air source, not a primary scuba tank.

**Q: Q2: Can beginners or non-certified users use this tank?**
A: 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.

**Q: Q3: How do I inflate it?**
A: You will need a high-pressure air compressor capable of producing 4500 psi, and you will need to ensure the air is dry and clean. Using a high-pressure manual pump, it would take over 500 cycles to raise a 0.5L cylinder to 3000 psi.

**Q: Q4: Can I use a regular air pump or tire inflator to fill it?**
A: No. Standard air pumps, tire inflators, or low-pressure compressors cannot reach the required pressure and should not be used. Only professional high-pressure scuba filling equipment is suitable.

**Q: Q5: Has it been DOT certified?**
A: Yes, all UNAROWHALS diving cylinders have passed DOT certification before they are allowed to be sold.
