An <a href="https://www.china-air-curtain.com/air-curtain/">Air Curtain</a>, also known as
an air door, is a machine that blows a controlled stream of air across an opening to the other
side to create an air seal. This seal separates different environments while allowing a
smooth, uninterrupted flow of traffic and unobstructed vision through the opening. Because
they help to contain heated or conditioned air, they provide sizable energy savings and
increased personal comfort when applied in industrial or commercial settings. They also help
to stop the infiltration of pollutants and flying insects.

<strong>How Does an Air Curtain Work?</strong>
</p>
<ol class=" list-paddingleft-2" style="list-style-type: decimal;">
<li>
<p>
Once it is powered on, air is brought into the unit through the intake
</p>
</li>
<li>
<p>
The air then enters the fan housing and is accelerated by the fan.
</p>
</li>
<li>
<p>
This fast-moving air goes into a plenum, which allows for an even distribution of
air along the full length of the discharge nozzle.
</p>
</li>
<li>
<p>
Airfoil-shaped vanes in the nozzle create a uniform air stream with minimal
turbulence.
</p>
</li>
<li>
<p>
The air discharged through the nozzle creates a jet stream to the floor.
Approximately 80% of the air returns to the intake side of the <a href="https://www.china-
air-curtain.com/air-curtain/air-curtain-door/" target="_self">Air Curtain Door</a>, and 20%
goes in the opposite direction.

<strong>Why Use an Air Curtain?</strong>
</p>
<ul class=" list-paddingleft-2" style="list-style-type: disc;">
<li>
<p>
Energy savings through control of air transfer
</p>
</li>
<li>
<p>
Energy savings due to shorter run times of air handler or compressor
</p>
</li>
<li>
<p>
Safe environment support by increasing ventilation and de-stratifying the air
</p>
</li>
<li>
<p>
Maintain employee/customer comfort
</p>

<strong>Do Air Curtains Cool a Room?</strong>
</p>
<p>
While <a href="https://www.china-air-curtain.com/air-curtain/air-curtain-blower/"
target="_self">Air Curtain Blower</a>s are not the same as air conditioners, they are highly
effective at maintaining the interior temperature, keeping cool air inside and warm air
outside (or vice versa) when the door is open. They are sometimes referred to as “invisible
doors” as they create an invisible barrier between inside and outside environments. Because
they help to contain heated or conditioned air, they provide sizable energy savings and
increased personal comfort when applied in industrial or commercial settings.

<strong>Do Air Curtains Keep Flies Out?</strong>
</p>
<p>
Yes! And mosquitos, yellowjackets, and bees. <a href="https://www.china-air-
curtain.com/air-curtain/air-curtain-fan/">Air Curtain Fan</a>s, sometimes referred to as fly
fans, supply a high velocity stream of air across a door or window opening that keeps pests
like insects from entering the building. These flies and other small insects, find the air
stream too powerful for them to fly through and if they try, they are blown down or sideways
before they can enter the building.

<a href="https://www.china-air-curtain.com/air-cooler/">Air Cooler</a>s, also known as
evaporative or swamp coolers, cool an atmosphere by evaporating water. As air flows over
water, certain particles on the water's surface are carried away. These particles take the
heat with them, and this allows the air to cool. This is the main mechanism behind air
coolers. Continue reading the article to know more about them.
</p>
<p>
<strong>How Does Air Cooler Work With Water?</strong>
</p>
<p>
Sweating also functions in the same way: the water particles on the skin's surface
bring heat away with them as they evaporate, cooling the skin. It is also known that these air
coolers are able to make use of 75% less energy as compared to the central air conditioners.
</p>
<p>
Evaporative coolers come in a variety of styles. A fine mist is sprayed into the air and
then whipped out by a fan in some methods. Since the water in this mist is made up of fine
droplets, it evaporates easily and absorbs heat from the air. In some other methods, the air
is made to blow through a material that has been wetted. It can be blown through a fine mesh
or past wet sheets, for example. This wet material then cools as it evaporates, and this, in
turn, cools the air.
</p>
<p>
<br/>Ventilating a building simply replaces stale or foul air with clean, fresh air.
Although the ventilation process is required for many different applications, the airflow
fundamentals never change: Undesired air out, fresh air in. The key variables that do change
depending on applications are the fan model and the air volume flow rate (CFM). Other
considerations include the resistance to airflow (static pressure or SP) and sound produced by
the fan (Sones). Sometimes you need a <a href="https://www.china-air-curtain.com/exhaust-fan/"
target="_self">Exhaust Fan</a> to perform a particular function, but it’s not clear which
model to use or even what CFM is needed. If this is the case, you’ll need to do some fan
specification work. Fan specification is not an exact science, but it can be done confidently
when the fan application is understood.
</p>
<p>
Fans all perform the basic function of moving air from one space to another. But the great
diversity of fan applications creates the need for manufacturers to develop many different
models. Each model has benefits for certain applications, providing the most economical means
of performing the air movement function. The trick for most users is sorting through all of
the models available to find one that is suitable for their needs. Here are some guidelines.
