The use of air curtains has now become common at work premises, storage areas and industries for keeping the temperature of the place cool and relevant. 

The device blows a good amount of air that stops insects, flies and pollutants from entering inside the place. They are especially mounted to keep the environment clean and dust free. They control the flow of warm and cold air as per the climatic conditions outside. 

An air curtain is the electronic device that is fan-powered and it creates an invisible barrier over the doors and windows that limits the entry of fumes, flies and other pollutants inside the resident, industrial buildings and commercial places

It is a continuous broad stream of air circulated across the doorway of a conditioned space that reduces penetration of insects and unconditioned air into the conditioned space. It forces an airstream over the entire entrance that blocks the path of insects and flies.

How Do Air Curtains Work?

The device runs on electricity but consumes low electrical units as compared to other air cooling devices. If we talk about the working of an air curtain then it consumes different units and voltages as per the model. 

The device is equipped with two or more fans that extracts all the warm air along with dirt and pollutants and flows out cool and fresh air in the atmosphere. 

The air door has a grille that helps to easily extract the bad odor, fumes and dust which is compressed by the internal fans. It has a filter that cleans the air and then circulates it in the atmosphere. The most common types of flow are axial, centrifugal and cross-flow. 

The air stream works with a velocity and angle such that any air that tries to penetrate the curtain is restricted.

In high traffic areas such as supermarkets, hospitals and heavy duty industries where there is constant foot traffic the recirculating curtains are a perfect choice. They are usually built at the entrance while the construction work is going on. 

A discharge grille is mounted at the floor that emits air from one side and collects it through the grille on the opposite side that returns through duct-work to the discharge grille. The low velocity air created by recirculating air curtains is more desirable for separating environments.

Non-Recirculating

The non-recirculating air curtains are more widely used as compared to the recirculating one as these types of air curtains discharge the air to the environment. 

They are easier to install and have low maintenance. They are usually mounted horizontally and it gives an excellent architectural appeal to the place.
