UNAROWHALSUNAROWHALS Mini Scuba Tank, 5-10 Minutes Usage Time Scuba Tank Kit, DOT/CE-EN250 Certification Dive Tank, 0.5L(3.5Cu Ft) Capacity Portable Scuba Tank, 3000 Psi Max Pressure, Aluminum Diving Tanks
Main highlights- Usage: This cylinder requires you to assemble it yourself, there is no gas in it, so please make sure you have high-pressure filling equipment before purchasing. 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 entry and exit of gas in the bottle to prevent accidental leakage.
- 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.
- Package contents: Includes a 0.5L gas cylinder, a constant pressure breathing valve, a portable bag, 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.
- 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.
- 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.
