What You Need To Know About Air Doors

One day you are walking through the entrance of a supermarket or another commercial building. Then all of a sudden as you pass through the door you felt a gush of air. The weird part of it is that the air was pushing down on you. The contraptions responsible for that are called air doors and there are many uses for these.

Let us first describe what air curtain, as an air door is more officially called, is and what is its main purpose. It is a device placed at the entrance or doorway of a confined space that releases a strong air current covering the whole height of that entrance. It creates an invisible barrier which prevents the entry of flying insects and unconditioned air.

Industrial climate control is one of the best uses of an air door. These air curtains are more commonly found in the shipping and receiving rooms or traffic doors of plants, factories and warehouses where the quality of the air need to be controlled every single time otherwise their products or goods might be affected. An air curtain is then designed to have its air nozzle pointed at the direction of the incoming air, usually air coming from the outside from another room. When these two air streams collide, they will push each other downward to the floor, resulting to that curtain of air that we feel each time we pass through it.

If you have an oven and you want to conserve up to 40 percent of your usual fuel used to operate that oven, then consider having an air door installed on top of the oven. You will need to aim the air nozzle to the opening of the oven with the purpose of the stream of air meeting head on with the air that is trying to come out of the oven. This will then result with the escaping hot air being pushed back into the oven and therefore making full use of all of the heat available in there. This is how you can save a great deal of energy.

You can also use air doors to help maintain the air quality of air conditioned areas. As expected the air door will be placed on top of the main doorway. What it does is to prevent the much hotter air from the outside from entering the air conditioned room. This in turn will help in keeping the desired temperature inside the room when it is the kind of area that is frequented by people, therefore a door that is always opening and closing will be less efficient.

When a specific rooms needs to be controlled from dust and humidity, having an air curtain installed is a good idea. By placing it, again, over the doorway and its stream of air pointed right at the direction where the dust particles are expected to originate, you will be able to better maintain the air quality in that room. This while not intervening to the need of people to go in and out of that room as often as needed.

These are just some of the common uses of air doors or air curtains. As you can see an air door is primarily and sensibly used in commercial and industrial establishments, all the time contributing to not only in the quality of the air in the rooms but also the production level of the whole operation.
