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, and that is 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. But what exactly do vape airflow holes do, and how does airflow work? This and more will be answered in today's blog. If you're ready, let's dig in.

What is Vape Airflow 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. The amount of vape airflow in your device can change many things in your vape. Airflow control is responsible for flavor, vapor production, the warmth of the vapor, and the feel of the vapor when inhaled. Sometimes, airflow can even have more of an effect than increasing the power on the vape device.

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. More air means a more diluted flavor since the vapor gets cooled. Airflow also controls the temperature of the vape clouds created. Less airflow also means a hotter vape, while more airflow cools down the vapor. 

When it comes to cloud production, restricted airflow will not create as big clouds as expected since there will be less air. At the same time, too much air and the vapor become 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.  

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.

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 rebuildable tanks, these types of airflow control the under coil inserts. They also significantly impact the vaping experience since the airflow goes directly to the coil center, now coiling it down. As we already explained, it generates a more significant impact on all the things mentioned above. 

The way under coil inserts work is to enter through the coil insert at the bottom of the tank, then the juice enters the atomizer through the tank’s wicking holes, and inside the atomizer, the air, and the vape juice mix together where it exits through the drip tip. 

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 rebuildable, where a ton of different coil designs can be used, creating different vaping experiences.


Airflow control might not feel as significant as other vape settings. Still, 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.
