## Overview

The UNAROWHALS 0.5L mini scuba tank is a DOT-certified, aviation-grade aluminum diving cylinder delivering up to 3.5 cubic feet of air at 3000psi. Designed for convenience and safety, it features an upgraded constant pressure breathing valve and multi-layer filtration for clean air. Ideal for snorkeling, shallow dives up to 33 feet, or as a backup air source, it comes as a complete kit with a full-face mask, hand pump, and carrying bag, enabling quick, portable underwater exploration.

## Description

The unarowhals scuba diving tank is made of aviation-grade aluminum and uses an upgraded breathing valve core to provide you with a better user experience. At the same time, the diving tank has a three-layer filter device that can effectively prevent dust and impurities from entering, making the inhaled gas cleaner. All products are DOT certified, so you can use them with confidence. Its maximum diving depth is 33 feet, and it can be used as a backup air source for deep diving within a depth of 100 feet. Small diving tanks are suitable for underwater exploration, boat cleaning, emergency rescue, backup air source, etc. The use time of a 1L is 10-15 minutes, depending on your diving depth and breathing rate. Of course, no matter what capacity of diving cylinder, there are two ways to inflate: 1. Use the scuba adapter, 8mm inflation port, connect to a standard large diving tank, and your diving cylinder can be inflated in 10 seconds. 2.4500psi air compressor, 1L diving tank inflation, about 20 minutes to complete.

Review: No instructions, very hard to use and fill. - I bought one in blue and my Fiancé got one in black. We got them back around Christmas and now that its summer we are trying to use them. Very confusing, doesn't come with instructions. Im pretty sure the black one is broken when you try and fill with air you hear the mouth piece hissing and the button doesn't release air. Plugged up the blue one to the compressor and its actually filling up but the mouth piece is also hissing and its taking a very long time to fill the valve goes up extreamly slow. Hopefully im doing it right since the are No instructions.
Review: Simple to use. - Great product for the price. Need to pump non stop for 15-20 mins to completely fill though.

## Features

- Compatibility: When these scuba tanks are used with a compatible diving mask, the snorkel mask draws air from the outside when on the surface, and when underwater, the air from the diving tank automatically fills the inside of the mask, allowing you to breathe freely through your nose and mouth. Whether snorkeling along vibrant coral reefs or conducting shallow dives in tranquil lagoons, it will provide users with the flexibility to immerse themselves in different aquatic environments.
- Convenience: Mini scuba diving tanks offer convenience like no other. This scuba tank can hold 3.5cuft of air at a pressure of 3000psi, which can be used underwater for about 5-10 minutes. They eliminate the need for bulky dive gear and extensive setup processes. With a mini dive tank, divers can enjoy quick and easy access to underwater exploration. Whether it's a snorkeling trip, a shallow dive, or underwater photography, these small scuba tanks provide hassle-free diving experiences.
- Safety: While scuba air tanks are smaller in size, they are engineered 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 functioning and air supply during dives. They are rigorously tested and DOT-certified to guarantee the safety of divers. With mini diving tanks, divers can go on underwater adventures with peace of mind.
- Instructions for use: This gas cylinder needs to be assembled by yourself, and there is no gas in the bottle. There is a multi-layer filter device at the gas cylinder interface to prevent dust and impurities from entering the bottle. The bottle head is equipped with a switch to freely control the in and out of the gas in the bottle to prevent accidental leakage. The manual pump in this set can inflate this device, but it takes more than six hundred times to fill a 0.5L scuba tank.
- Package contents: Includes a 0.5L gas cylinder, a constant pressure breathing valve, a high-pressure hand pump, a big handbag, a full-face mask, a mask adapter, and an anti-lose 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.

### ⭐⭐⭐ Runs outta air quickly

Works good, but runs outta air quickly. You'll need a special electric air pump to fill it up.
