Have you ever walked into a store, a hospital, or a hotel lobby and felt that steady flow of air right at the entrance?
You walk in, and the inside feels cool and clean. Well, that invisible layer of air is doing a lot more work than it looks like! That’s where the question usually comes up: what is an air curtain, and why are so many commercial spaces using it now?
An air curtain is one of the things you don’t notice until it’s missing. It quietly controls the temperature, keeps dust and insects out, and helps businesses save energy.
Surprisingly, over the last few years, air curtain use has grown rapidly across India, especially in places like restaurants, hospitals, malls, offices, and industrial spaces where doors open constantly.
We at Novatech are focusing on introducing practical and durable air curtain systems that work well in real Indian conditions, where dust and humidity are normal.
So if you are wondering what an air curtain is used for, how it works, and whether it actually makes sense for your space, you will get all your answers here!

ToggleWhat Is an Air Curtain and How Does It Work?
At its core, an air curtain is a device that is installed right above a doorway that pushes a strong, yet controlled stream of air straight down.
If you look up air curtain images, you will probably find them at the entrances of retail stores, hospitals, restaurants, commercial kitchens, warehouses, and office buildings.
They are quite slim and minimal, so no one can actually even see where the air is coming from. And while no one can tell, they still make a noticeable difference to how a space feels.
This is why people often ask, what is an air curtain used for?
The simplest answer is this: it keeps the good air inside and the unwanted air outside, without slowing people down. That balance between comfort and convenience is the core air curtain purpose.
Here is how an air curtain works and all you need to know about it:
- The unit pulls in air from its surroundings.
- A powerful internal fan pushes this air downward.
- The air flows in a steady, uniform sheet across the doorway.
- The airflow blocks dust, insects, heat, humidity, and pollution from entering.
And that’s literally it! A well-designed air curtain system doesn’t feel aggressive. It doesn’t blast cold air in your face. It doesn’t make the entrance noisy or uncomfortable. It simply does its job quietly, and that’s exactly why air curtains are used in so many modern buildings.
5 Purposes of an Air Curtain
Now let’s talk about the real reason why businesses invest in these systems. The air certain purpose is not just for one thing, but to actually solve multiple ones at once:
1. One of the biggest reasons why air curtains are used is temperature control. Every time a door opens, conditioned air escapes, and so an air curtain reduces that by acting as a thermal barrier.
2. In Indian cities, dust and pollution are constant problems, and well, open doors make it even worse. This is where the air curtain really shines as it prevents dust from entering, insects from flying inside, and smoke and odors from drifting in.
3. If you’re still wondering what an air curtain is used for in healthcare or food spaces, hygiene is a major reason. They reduce airborne contamination and help to maintain a cleaner indoor environment. And well, when you pair them with Novatech accessories like sensor-operated taps, automated hand dryers, and touch-free soaps, the overall level improves!
4. Another reason why air curtains are used instead of doors is convenience. You will never need to push, pull, or wait as people, wheelchairs, carts, and trolleys can move freely.
5. You may not consciously notice it, but a space with a well-installed air curtain system feels much better. There is no sudden heat, no dust gusts, no outside smells, and all you get is a clean, comfortable entrance.
Types of Air Curtains & Specific Uses
And just when you think you know all about air curtains, there come the types of them! Yes, not all air curtains are the same, as different spaces need different solutions:
1. Ambient Air Curtains

These ones are pretty simple, non-heated systems that are designed mainly for dust, insects, and airflow control. You will often find them in malls, offices, and retail stores where temperature balance is already managed.
2. Warm Air Curtains

A warm air curtain stays true to its name and includes a heating element that adds warmth to the airflow. These are very helpful in:
- Cold weather conditions
- Air-conditioned spaces during winter
- Temperature-sensitive environments
In fact, many air curtain images from hotels and premium buildings you will see show warm air curtains being used for added comfort.
3. Industrial Air Curtains

As the name suggests, these ones are built for larger openings and handle warehouses, factories, and loading bays. And because of their usage, their air curtain system design focuses on strength, durability, and continuous operation!
