What are the air door?

Air Doors use powerful blowers to create air curtains that can be used to separate two different environments. The air door can be used between different zones controlled by climate in the structure or to separate the interior of the building from the exterior. The air pressure force should prevent the air from penetrating the hinge on both sides, although the high wind can reduce efficiency. Normal use of air doors is to prevent insects or dust to enter the building or to improve the efficiency of the heating, ventilation and air conditioning system (HVAC). When the device is on, the air blows down at high speed. This can prevent the air from mixing on one side of the curtain with the air on the other side. Although it is less efficient than a physical door with good seal, it can also allow people, vehicles and other objects to move between two different environments.

the ability of air twoRome to effectively separate two environments largely depends on the power of the blower fan. BLOV with a higher speed will tend to prevent the two volumes of air from mixing, especially on the outside of the building where winds could be present. These thick blowers can be unpleasant for people, under which they can walk, so weaker, less effective units are often used in commercial devices.

When air doors are used inside the structure, it is often intended to separate two zones controlled by climate. One way to use air doors is commonly used to prevent freezing of freezers or colder rooms after each door opening. This can increase the efficiency of not only the freezer for the freezer, but also the heating system for the rest of the building. In other cases, the air door is placed on the outside of the building where it can maintain internal temperature or maintain dust, insects and other undesirable items in the entrance.

air doors can be placed in the door itself o sboth or be used in conjunction with the physical door. When the air door is used by themselves, it is usually set to blow. They are often used to load dock inputs, where the door remains open throughout the working day. The air doors that are used in conjunction with the physical door can be set to turn on if the door is open. These are often used in commercial stores and other devices where customers come and leave all day.
