    An Air

    , 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


    How Does an Air Curtain Work?
    Once it is powered on, air is brought into the unit through the


    The air then enters the fan housing and is accelerated by the fan.

    This fast-moving air goes into a plenum, which allows for an even

    distribution of air along the full length of the discharge nozzle.

    Airfoil-shaped vanes in the nozzle create a uniform air stream with

    minimal turbulence.

    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

    Air Curtain Door, and 20% goes in the opposite direction.

    Why Use an Air Curtain?

    Energy savings through control of air transfer
    Energy savings due to shorter run times of air handler or compressor

    Safe environment support by increasing ventilation and de-stratifying

    the air

    Maintain employee/customer comfort
    Reduce flying insect infiltration
    Unhindered traffic flow & unobstructed visibility across the


    Increase productivity due to stable temperatures
    Maintain usable space around the door
    Elimination of ice and fog in cold storage areas

    Do Air Curtains Cool a Room?
    While Air Curtain Blowers 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.

    Do Air Curtains Keep Flies Out?
    Yes! And mosquitos, yellowjackets, and bees. Air Curtain Fans,

    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.

    How Much Does an Air Curtain Cost?
    Electric Air Curtains can range in price depending on

    features, the application, and specific requirements. Consult a

    Air Coolers,

    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.

    How Does Air Cooler Work With Water?
    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


    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.

    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 Exhaust Fan 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.

    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.

    An indoor Air

    ensures the filtration of air within an

    enclosed/closed place, which is processed then released as purified

    air. It operates as a complement to natural ventilation where it is

    possible to open windows.

    It is vital to distinguish a professional model from a consumer

    device: they do not both guarantee identical air treatment or

    comparable overall performance.

    A professional air purifier, equipped with a HEPA 13 or 14 filter,

    will operate effectively on pollens, fine particles PM2.5 and PM10,

    VOCs (Volatile Organic Compounds), viruses and bacteria. Finally, the

    device’s benign operation is key: that is to say the air purifier

    itself does not generate any secondary pollutants. To limit the

    diffusion of harmful residues, allergens or even viral elements;

    prevent asthma or allergy problems linked to poor indoor air quality

    to people at risk (children, elderly or sensitive people).

    A Home Air Purifier, not to be confused with an air

    ioniser or air humidifier, can be used as a preventative and/or

    therapeutic measure: at home, in enclosed offices, open spaces or

    coworking sites, shops, hairdressing salons, hotels or restaurants,

    medical and paramedical offices… By extension, as Covid-19 is

    obliging us, it is assuming an expanding r?le in schools, hospitals,

    medical and paramedical sectors, services.
