Vape Airflow Holes: What They Do And How Does Vape Airflow Works

There are many things you can do to improve your vaping experience. You can buy new devices, get a coil better suited for your needs (for example, a mouth-to-lung or low resistance coil), create a new coil design if you use a rebuildable, or buy a brand new vape juice with different vegetable glycerin or propylene glycol ratio. Whatever your goals, whether cloud-chasing or flavor chasing, you can achieve them by switching all these components. However, there is one component that does not get enough attention: airflow control.

While not all vape devices come with airflow control, those users who own vapes can experience a quick and efficient way of changing the flavor, vapor temperature, cloud size, and even the harshness of the vapor simply by changing the airflow control. But what exactly do vape airflow holes do, and how does airflow work? These and more will be answered in today's blog. So If you're ready, let's dig in.

What is Vape Airflow? And What Does The Airflow On A Vape Do?

Vape airflow is the amount of air that is introduced into the vape at the moment of inhalation. In other words, the purpose of airflow on vapes is to control how much air is introduced into the vape, and believe it or not, this can change many things in your vape experience. Airflow control can change the flavor, vapor production, the warmth of the vapor, and the feel of the vapor when inhaled. 

Is Airflow Important?

Airflow is just as crucial as the coil you use and the type of vape juice you choose, although people often forget it’s even there. If you are using temperature control devices, airflow control is super important since it will cool the coil and the vape device will have to use more power to function. With Tanks and RDAs, it’s essential to try adjusting the airflow control before attempting to change other settings. 

Vape airflow is also necessary because it can control the flavor. Too much airflow on a vape means a more diluted flavor since the vapor gets cooled, less airflow means more flavor. Airflow also controls the temperature of the vape clouds created; less airflow means a hotter vape, while more airflow cools down the vapor. 

When it comes to cloud production, restricted airflow will not create as big of clouds as expected since there will be less air. At the same time, too much air and the vapor becomes thin. A middle-of-the-road airflow control setting will give you massive thick plumes of vapor.   

Airflow can also affect the throat hit or harshness of the vape. A harsher vape or a more intense throat hit means a more cigarette-like experience. The more airflow there is, the less severe the vape will be.  

Does More Airflow Use More Juice?

Believe it or not, airflow control can also affect how long the vape juice lasts. For example, the coils burn cooler with high airflow control, which means less vape juice is evaporated, while the opposite is true; with less airflow control, the coils burn hotter, meaning much more vape juice is evaporated.

Does Airflow Affect Coil Life?

The verdict is still out on whether or not airflow can affect coil life. But the answer is that it is most likely. Since the two number one enemies of coils are flooding and poor wicking, one could say that with a restricted airflow setting, when inhaling, you are more likely to draw more juice into the cotton, which can cause flooding. And with a wider setting, less juice will be drawn into the cotton, creating dry hits that can put a strain on coils. 

How Does Vape Airflow Control Work?

There are two types of airflow control, airflow control rings (AFC Rings) and under coil inserts. These, by far, are the most prevalent air flow controls on vapes. In the sections below, we’ll go over how both of these work.

Airflow Control Rings

Airflow control rings are by far the most popular kind of airflow control in vapes. They are the most common and can be found in most tanks with 510 connections. These rings can be rotated to expose slots or large holes where the air can come in. Most of these airflow controls have sections that click in and out, giving various degrees of control depending on how much air the user wants to let in. By playing around with these settings and power settings, you can fine-tune your vaping experience to be unique.

Under Coil Inserts

Almost always found in high-end rebuildable tanks, this type of airflow control will use bottom holes that will allow the air to enter, but the air will come out of inserts positioned directly under the coil instead of simply entering the atomizer chamber. While the AFC rings can easily change the type of airflow by being rotated, with under coil inserts you have to physically attach and remove the different types of inserts that go directly below the coil inside the tank to change the airflow type. And while this might seem a bit tedious, the effects are more drastic since the air hits the coil directly. And as we already explained, airflow that hits the coils directly generates a more significant impact on all the things mentioned above. 

Some under coil inserts have a “showerhead” arrangement that disperses the air in the atomizer, while others restrict or direct the air directly toward the center of the vape coil. These types of airflow control are perfect for rebuildables, where a ton of different coil designs can be used, creating different vaping experiences.

Below you will find some tanks that offer great airflow control and will work with most vapes that have a 510 connections. Since AFC ring airflow control setups are the most common and easy to use, these are the ones that we have chosen below. 

Wake Sub Ohm Tank by Wake Mod Co Hardware

This tank is quite a beast. It features plenty of attractive specs, but most importantly it has bottom airflow control that is controlled by a top ring, allowing you to easily change the airflow setting without having to stop your vaping session. In fact, we think you can probably control the airflow while hitting your vape. Available in six different colors, it comes with two extra 0.5ohm coils, an extra glass, and spare o-rings in case you lose them. 

UWELL Crown V Tank

The UWELL Crown V Tank is perhaps one of the best tanks we offer. It also happens to feature a top ring that controls the bottom airflow control, allowing to adjust the exact width of the opening of the airflow. Available in four colors, it comes with a replacement glass, two mesh coils, a pack of o-rings, a user manual, and a drip cover.

Made out of stainless steel, this tank is another great option. It features a bottom adjustable airflow control that has 5 bored airflow holes of different sizes, which allow you to easily change the airflow setting on the fly. Available in six colors, it also comes with a replacement glass. 


Airflow control might not feel as significant as other vape settings, but if taken into consideration when making adjustments to fine-tune your vaping experience, you’ll find yourself enjoying a more personalized vape. Although it might seem as if airflow holes have little significance, we can’t overstate their importance when it comes to creating a unique vaping experience. 

Airflow can control the temperature of each puff, the cloud production, the flavor, and even the throat hit, yet some people will first change their vape juices and our coils before adjusting the airflow holes. Although a vape juice or coil change is warranted, sometimes all you need is to adjust your vape device's airflow control.
