Sub ohm tank is not new in the vaping industry, but upon releasing, the vaping world changed. If you want to sub ohm using these atomizers, you need to build the coils yourself in a rebuildable dripping atomizer (RDA). If you desire a tank, you must use a rebuildable tank atomizer (RTA).

Now, you don’t need to build your own coils with sub ohm tanks. It already offers replacement coils heads that are less than 1.0 ohm resistance. This is the only big difference between this device and other vape tanks available on the market. Because of this, the sub ohm tanks became popular in the vaping industry. It also makes the process simple and easier for the vapers, especially those who are switching from cigarettes. Before we discuss deeper about it, let us define the basics.

Sub ohm tank is also known as sub tank, sub ohm clearo tanks, or sub ohm clearomizers. This is an atomizer with a resistance that is less than 1.0 ohm. It also refers to devices that either has one or multiple coils. If you use many coils, you must consider the collective resistance of all coils.

After enough time has passed, the term got many definitions and became a hit in the marketing. It got featured with certain characteristics, such as a pre-made factory-built removable and replaceable atomizer head. This part attaches to the base portion of the tank. This means that this device is both generic and marketing name. To learn more about sub ohm tank, check out the official website of OFRF.

The Evolution of Atomizers

1. Dripping Atomizers

Numerous stages happen in the development of atomizers. Many people wonder what is sub ohm tank and how did it start. First, there were dripping atomizers. A coil on the ceramic base was inside the metallic shell shaped like a cylinder. You needed a threaded connector to join the shell to the bottom part of the power source. The open end of the tube allowed the e-liquid to travel to the coil. Later on, the manufacturers customized the atomizers and sold two sections: the cylindrical version with the coil and the other one with the wicking material.

2. Clearomizers

This kind of atomizer is the second stage. It has a metal tube with a cylindrical shape. One hand has the electrical connector, while the other has an opening that lets the e-liquid travel. The wick gets soaked with e-liquid. It is a piece of silica polyester or similar to the blue foam.

3. Clearomizer Tank

The makers of the clearomizer tank improved the previous models. The metal tube has either drilled or punched holes. Glass or plastic composes the sealed container. This is where the e-liquid is placed. When the vaper inhales, the pressure drops. Then, the vape juice moves to soak the wick. Homemade remodeled syringes are the first batch of this improved clearomizer tank. These syringes were cut into sections.

4. Factory Versions

The manufacturers created the factory versions to standardize the clearomizer tanks. The punched tubes are no longer present in the tanks. There are coil heads and long wicks reaching the reservoirs for e-liquid. After further remodeling, the disposables became nondisposable tanks having removable heads. They feature the resistance of the coil with 1.25 to 5 ohm. They don’t drop down lower than 1 ohm.

5. Sub Ohm Tanks

The sub ohm tanks produce low resistance which provides more power. This results into thick vapor or better flavor. The Ohm’s law is used to learn about electricity. The new tanks feature coil heads that are easy to remove and come with the coil resistance of 0.5 ohms. The launch of the first clearomizer tank was in 2015. On the next year, the first rebuildable tank atomizer (RTA) gave birth.
