How Much Does a Steel 100 Scuba Tank Weigh?

September 25, 2022 4 min read

When looking for a SCUBA tank, it is important to know how much it weighs. A steel tank is a lot lighter than an aluminum tank, which means that you will have to carry less weight. In fact, an aluminum tank will add about 11 pounds of weight to your weight belt, while a steel tank will require only 11 pounds. I personally have a friend who was an air hoarder when he first started diving. His instructor suggested a peak performance buoyancy course which helped him to use a steel tank. That tank gave him an extra 20% of bottom time, which was great! This allowed him to match his dive time with his time on the bottom. That way, he could remove weights from his weight belt and not have to worry about running out of air.

Steel 100 Scuba Tank

The steel 100 Scuba tank weighs about 31.4 pounds (14.2 kilograms) empty, but that's only if it's empty. It's actually positively buoyant, but its weight is still a factor to consider. This type of tank is highly appreciated and valued by scuba divers around the world. The empty weight of a steel 100 SCUBA tank is considerably lighter than a typical aluminum tank, which can weigh 40 pounds (18kg).

Another consideration is working pressure. Many tanks have working pressures up to 3440 PSI. This is important because cylinders aren't considered full until they're filled to that pressure. You'll also want to consider the size of the tank. This is especially important for younger divers, because a large tank can bang into their legs and head. A standard tank typically measures 7.25 inches in diameter and is about twenty to thirty inches long.


A technical diver needs to know how much breathing gas to take when he is entering the water. There is a mathematical relationship between the internal volume of a scuba tank, its maximum service pressure, and its actual free gas capacity. The internal volume of a tank is measured in cubic inches, while the free capacity is the amount of breathing gas that will be released at the surface. However, calculating the capacity of a tank is complicated and not everyone does math the same way.

Steel tanks are generally heavier than their aluminum counterparts, but are also stronger and more durable. However, the weight of a steel tank becomes an issue, particularly when you add in all of your Scuba gear.


There are several things to consider when choosing a Scuba tank. Generally speaking, a tank weighs from 26 to 40 pounds depending on the model. This does not include the weight of the valves or the tank's boot. These items aren't included in the weight of the tank, but they do weigh some weight. You must also consider the weight of snorkel.

The tank's buoyancy is an important consideration. A steel tank will start out negatively buoyant and will remain that way for most of the dive. Eventually, however, the tank will become neutrally buoyant. When empty, however, a steel tank won't float as far as an aluminum tank. That said, steel tanks are still lighter than their aluminum counterparts.

Scuba tanks have various service pressures. Low-pressure steel tanks are preferred by technical and Nitrox divers. Most aluminum tanks are rated at 3000 psi. Standard AL100 tanks and compact aluminum tanks have a service pressure of 3300 psi. High-pressure steel tanks are available under DOT Special Permits. Does full scuba tank weigh more? Let's find out in other articles.


Steel tanks have a number of benefits over aluminum ones. For one thing, they are more durable and last longer. They also are more expensive. However, steel tanks are still not at a level where bulk discounts are as effective as they are for aluminum tanks. For example, the Faber FX Series 100 cu ft High Pressure Blue Steel Tank is priced between $330 and $430. These tanks are extremely reliable and rugged, and they offer a higher air capacity.

Steel tanks are also lighter than aluminum tanks. Since they are denser, they require less mass to achieve the same air pressure. They are also less likely to dent or bend. They also have a higher negative buoyancy, which means that you can reduce your ballast weight with a steel tank.


When it comes to scuba diving cylinders, no other manufacturer can match Faber's range and capabilities. Whether you plan to dive on nitrox or want to dive with air, there's a Faber cylinder to meet your needs. Faber XS valves are a great choice for nitrox divers. You'll have no problem getting the right pressure for your dives with these valves.

The steel scuba tank has several benefits, including its lower weight overall and improved buoyancy characteristics. In fact, its design allows it to change from negative to neutral buoyancy throughout the dive. It also offers better performance for dry suit diving because of its greater buoyancy control. Moreover, steel cylinders are rated at 232 to 300 bar. Obviously, the higher the rating, the heavier and thicker the tank will be.
