Opening the door for customers shouldn't mean opening the door to dust, heat, and energy wastage. This is where the importance of air curtains comes in, but is simply having an air device above the door enough?
The truth is that choosing the right air curtain strength is not a random decision. The size of the entrance, the nature of the activity, and the intensity of usage all directly affect the efficiency of the air barrier. At Stavoklima, we face this question every day: which strength is right for my space?
In this article, we'll show you how to determine this precisely, based on the space dimensions, usage requirements, and appropriate airflow standards. Whether you’re considering installing an air curtain for a shop, restaurant, warehouse, or even a shopping center entrance, keep reading, and we’ll guide you to choose the optimal solution both technically and financially.
What’s the Relationship Between Air Curtain Strength and Door or Space Size?
Choosing the appropriate air curtain strength is not just a cosmetic decision; it’s a critical factor to ensure the effectiveness of the air barrier and reduce cooling or heating loss. The larger the door size, the higher the required capacity to generate a cohesive airflow that covers the entire area.
Here’s how the entrance dimensions affect determining the air curtain strength:
- Tall doors require air curtains with higher thrust power to ensure the airflow reaches the floor without dispersing.
- The wider the entrance, the greater the need for an air curtain with sufficient length to cover the area without leaving gaps that allow air or dust to leak through.
- For double entrances or areas with high traffic flow, the air curtain strength needs to be calculated precisely to prevent the air barrier from being breached.
- The match between the door size and airflow speed (CFM or m³/h) is essential for effective protection against external climate changes.
- Using a weak air curtain on a large entrance leads to failure of its intended purpose, while using a highly powerful curtain on a small entrance may cause annoying noise and unnecessary energy consumption.
At Stavoklima, we don’t leave this to guesswork. We study the door dimensions, usage nature, and suggest an air curtain with precise engineering specifications that achieve the balance between performance and efficiency.

How to Measure Door and Space Dimensions Before Buying an Air Curtain?
The first step in choosing the right air curtain starts here. Incorrect measurements mean ineffective installation or wasted investment. Therefore, we always recommend considering the following points when measuring the entrance:
- Measure the width of the door from the right edge to the left edge precisely, ensuring there are no obstructions in the upper space.
- Calculate the height of the door from the ground level to the top edge, as this measurement determines the air thrust power needed to reach the ground.
- Observe the type of door: manual, automatic, revolving, or industrial fridge door, as this affects the speed of closing and the number of operating cycles.
- Examine the space above the door to determine if the air curtain can be installed horizontally and visible, or if it's better to install it hidden within a suspended ceiling.
- Pay attention to the side walls, beams, or any nearby fixtures that may obstruct the full-length installation of the air curtain.
- Don’t neglect the surrounding area of the door, especially in open or wind-exposed environments, as this may require an air curtain with higher air pressure.
At Stavoklima, we offer technical consultation services to our clients in Saudi Arabia, helping you determine the exact measurements and choose the right model based on the space, without guessing or assumptions.

Criteria for Determining the Appropriate Airflow Strength for Air Curtains (CFM / m³/h)
Choosing the right airflow is not just a technical figure, but a critical factor in the performance of the air curtain. If the airflow speed is insufficient, the effective barrier won’t form, even if the dimensions are correct. Here’s what to keep in mind:
- Ensure that the airflow rate covers the full height of the door down to the ground without interruption.
- The higher the door, the greater the need for an air curtain with a higher CFM to ensure the air barrier remains intact.
- In areas exposed to strong winds or negative pressure, it’s best to choose an air curtain with a higher airflow rate to compensate for the impact of external air.
- Doors with heavy traffic (such as mall entrances or warehouses) require an air curtain that operates with consistent, high airflow to prevent air leakage.
- Ensure that the airflow is evenly distributed along the air curtain, not concentrated in the middle or varying across the sides.
At Stavoklima, we rely on precise calculations to determine the suitable airflow rate for each project. We don’t leave this to guesswork; every model comes with a diagram showing the appropriate airflow capacity based on height, width, and usage type. Don’t hesitate to request a free consultation!
Additional Factors Affecting the Choice of the Right Air Curtain
Even with matching dimensions and airflow strength, an air curtain may not be effective if actual operating conditions are not considered. These often overlooked factors can make a significant difference in actual performance:
- The type of activity determines the pressure level on the air curtain. Restaurants need to isolate odors, warehouses require thermal isolation, while shopping centers focus on comfort and quietness.
- The surrounding environment plays a critical role. If you’re in a dusty area or exposed to wind, you should choose an air curtain with higher capacity and more precise airflow distribution.
- The need for additional heating or cooling requires choosing an air curtain with Heating/Cooling functionality, ensuring temperature stability at the entrances.
- The permissible noise level in the area must be studied carefully, especially in offices, cafes, or hotels, where low-noise air curtains are preferred without compromising efficiency.
We take these factors into account during the feasibility study for any project, and we recommend custom models based on a thorough analysis of the site’s nature to avoid any operational surprises later. Contact us directly via WhatsApp!

Frequently Asked Questions: How to Choose the Right Air Curtain Strength Based on Space Size
1. Is measuring only the door width enough to determine the air curtain strength?
No, both the width and height should be measured accurately. The door height determines the required airflow strength (CFM), and the width determines the appropriate air curtain length. Ignoring either can lead to ineffective performance.
2. How much electricity does an air curtain consume?
Energy consumption varies depending on the model and operating speed, but it is generally lower compared to running air conditioning for extended periods without proper insulation. Our energy-efficient air curtains are designed to reduce electricity consumption effectively.
3. Is the sound of the air curtain disturbing in offices or cafes?
Stavoklima air curtains are designed with low-noise fans, and we offer special models with silent performance that suit quiet environments such as offices, cafes, and clinics.
