Used air curtains, also known as air doors or fly fans, are devices that blow a steady stream of air across a doorway or opening to create a barrier between two different environments. They are commonly used in commercial and industrial settings to maintain temperature control, prevent the infiltration of outside air, and keep out insects, dust, and pollutants.
Air curtains work by creating a high-velocity stream of air that acts as a barrier to separate two environments with different temperatures or air qualities. The air curtain can be mounted horizontally or vertically, depending on the application, and is typically installed above the doorway or opening. The airstream can be heated or unheated, depending on the desired temperature control, and can be adjusted to the appropriate speed to effectively block the influx of outside air.
One of the primary benefits of air curtains is their ability to save energy and reduce heating and cooling costs. By creating a barrier between two environments with different temperatures, air curtains help prevent the mixing of hot and cold air and reduce heat loss or gain through open doorways. This can lead to significant energy savings and lower utility bills over time.
In addition to energy savings, air curtains can also improve indoor air quality by preventing the infiltration of outside air and pollutants. They are commonly used in industrial and commercial settings where air quality is a concern, such as hospitals, laboratories, and food processing facilities. Air curtains can also help prevent the entry of insects and pests, which is particularly important in food service and storage facilities.
Air curtains are a cost-effective and energy-efficient solution for maintaining temperature control, improving indoor air quality, and preventing the infiltration of outside air and pollutants. They are widely used in commercial and industrial settings and can provide significant benefits to businesses of all types and sizes.
Air curtains are designed to separate two spaces from each other, usually at an exterior entrance. The most common set up for air curtains is a downward facing blower fan mounted over an opening, blowing air down and outward across the lower surface, an air barrier. Air curtains can come with a heater to heat the air. Normally the opening is an entrance to a building or opening between two spaces conditioned at different temperatures. Air curtains work with the internal air flow to keep the insects, dirt, and dust outside and the cold or hot air inside.
