An air curtain is an integral device used in private homes, commercial applications as well as in industrial sectors. They are known for creating an effective barrier through an invisible stream of air that prevents flow of air from the interiors to external area and vice versa. It is a device that is used for cooling, drying and cleaning within various manufacturing lines and other processes. In some application areas, it is also used as a good dust and thermal barrier.
Insect Repellant
Apart from that, it is increasingly being used for repelling insects and bad odor in various commercial and industrial segments. It is to be mentioned here that for greater effectiveness, an insect barrier would need floor level velocities of 4.0 to 6.0 m/sec. And this differs for other respective uses of the air curtain. Most of the air curtain varieties used as mosquito repellents is available in aluminum and stainless steel, for allowing greater durability.
Thing to Consider
However, many other things are also to be considered while determining the type to be used for your purpose. And they are:
• Application
• Opening dimensions
• Air currents
• Wind velocities
• Differential pressure
Hence, you should take into account all these considerations before getting an air curtain to repel insects and remove bad odor. Otherwise, the whole purpose on installing one would get lost. You can further minimize the optimum velocity effect in high velocity & insect barrier units by using a curtain absorption duct at the floor level. This also prevents the splitting of air curtains protective barrier & the resultant air ingression.
Application Areas
Among the various sectors where this device with air knife has been used effectively are hospitals & retail outlets, hotels, restaurants & fast food joints, Auditoriums, multiplexes & theatres, fertilizer plants & petrochemical complexes, yarn/textile mills, food processing & packing units, dairies & cold storages, pharmaceuticals & bulk drugs manufacturers and all ISO / WHO / GMP / HACCP certified companies.
Use air curtain to clean, cool or dry conveyors, webs or components or to get rid of insects and bad odor and get cost efficient results. As coolers it is as effective as the cabinet panel cooler.
