6 Best Air Curtains & Bonus Buying Guide 

The concept of ‘curtains’ is normally perceived as hanging cloths or blinds from rails attached above windowsills. ‘Curtains’ gives off the image of something that blocks light early in the morning when you want to sleep in. They can also block some wind, and definitely obstruct one’s vision. So, when you think of air curtains, do you think along the same lines? You’ll be surprised to find out that air curtains per se, are very different and are not even used on windows; and they don’t, in fact, block light at all. 

Air curtains are also popularly known as “air doors” for their capability to act as an invisible air barrier. They are fan-powered devices, installed over the doorway to create an invisible barrier between two separate environments. Air curtains blow out air across an opening to ensure that an air seal is created. Such an air seal is to let the warm or cool air inside remain inside without having the outdoor weather affect the temperature inside with a door opening and closing. Because the curtain is simply made up of air, it also allows for continuous flow of traffic and an unhindered field of vision through the opening.

Benefits of an Air Curtain

Amongst many advantages of installing an air curtain, one is undoubtedly ample energy savings as it assists in confining cooled or heated air. Air curtains have also been seen to increase personal comfort when installed in commercial or industrial settings. They protect the contained area with cold air, or warm air, depending on the indoor and outdoor temperatures. Safety from insects and pests is also guaranteed, along with fumes, bad odors, dust, and pollution. 

The effects of wind draughts can also be prevented from air curtains. Due to these advantages, a clean atmosphere with increased health and hygiene is prevalent in areas where air curtains are found on doorways. Air curtains have numerous benefits, and they make the cooling and heating system inside more effective, and worth every penny.

Things to look for to choose the right air curtain

Once you know which air curtains are available in the market with their respective features; it’s time you now see how to pick the best one depending on your usage. The way you use your product and the space it needs to be installed in will determine which air curtain is best for you. The key factors that you need to keep in mind are: 

1. The door’s height 

The whole purpose of the air curtain is to isolate the internal and external environment, and that can vary with the airspeed. Too high an airspeed or too low an airspeed can have respective consequences. Typically, as the air outlet distance increases, the airspeed decreases. Low airspeed reduces the effect of air curtains, therefore, when the air reaches the ground, it is not at a suitable speed and will hinder isolation. If the airspeed is too high, it causes discomfort to those passing through the air barrier, and will also disturb the air need the door. High speed also results in increased bills because of higher power consumption. Therefore, measuring the door’s height is important to ensure efficient and effective construction of the air barrier. 

2. The door’s width

The width of the door will help you in purchasing an air curtain of the appropriate size. If the size of the air curtain is shorter than the width, then air will not be blown in the uncovered area, defeating the whole purpose of installing an air curtain. If the curtain’s width is greater than the doorway width, then the money paid will be greater than your requirement and will also result in greater electricity bills. If the air curtain is not purchased with an appropriate length, it will either lose function or simply waste your money. Hence, make sure you measure the width precisely and put it up against the length of the air curtain. 

3. The general purpose of your air curtain

Air curtains are becoming increasingly because of their returns on investment. The purpose behind purchasing an air curtain will determine how much you’re willing to spend on them. If you’re using air curtains for commercial use, then the benefits of it will outweigh your initial investment as its benefits are uncountable. Almost every business user installs air curtains for their commercial use to reduce energy consumption, maintain hygiene, and truly isolate the indoors from the outdoors. 

If you’re using air curtains for decorations, then your requirements will differ. If the store is small and works on a low scale, then it’s best to use cost-effective air curtains. But, if they’re being installed in shopping malls or larger stores, then air curtains are purchased for decorative effects as they can then be matched with the brand’s benefits. Moreover, if you’re using air curtains for industrial purposes such as warehouses, then more powerful air curtains will become the need of time. 

4. The climate in the installation’s location 

Knowing the air temperature throughout the year helps in selecting a more suitable air curtain. In winter, if the temperature is 20 degrees or more, then a heated air curtain may not be required. However, if the temperature is lower in winter, then you will likely need a heated air curtain. 

In coastal areas, the humidity is generally higher. High humidity in the air is corrosive for equipment compared to other climates. For this reason, air curtains are specially designed for humid or coastal areas, so be sure to pick the right one. Lastly, If the installation location encounters frequent winds, then an air curtain with increased power is required. 

5. The pressure difference between the external and internal environment 

An air curtain’s function is to isolate the indoors and outdoors, preventing an exchange between the temperature as well as the pressure. Thus, knowing the pressure difference is important as gas will flow from a region with high pressure to a region with low pressure. If the air pressure difference is high, then the air circulation between the two environments will be quicker. Hence, choosing an air curtain with a higher speed would be more suitable for this case. 

6. The door’s structure

The door’s structure dictates how an air curtain should be installed, and, subsequently, which one is most applicable for it. If the air curtain always has to remain turned on due to the door opening and closing frequently, then ensure that the air curtain you select can operate for longer hours. However, if the doors are induction doors, then air curtains can automatically turn on or off. 

If there is no space to hang air curtains on the doorway, then air curtains can be installed vertically – one on either side of the doorway or just on a single side. Revolving doors make the situation more complicated, and for that, you will need to contact an expert in the field before purchasing an air curtain. 


The factors mentioned above are key elements you should keep in mind before investing in expensive equipment such as an air curtain. Use these factors and their effects to properly understand what your exact expectations are from an air curtain, and how you can fulfill these requirements. Knowing this will help you in making the best decision when selecting which air curtain is the right one for you. So, use this buyer’s guide and other best air curtain options to find your choice.
