Description and introduction about air curtain door

You can see air curtains in many places like restaurants, malls, air hangars, waiting rooms, customer entryways, and office entrances, generally, these air-conditioned places where technical or due to the inconvenience of substantial influx and efflux of public it’s not feasible to close the doors. Otherwise, some large buildings with different working sections also install air curtains, though they are generally used on exterior entrances.

In such cases, these air curtains work as a barrier between the outside and inside air and hence prevent intermingling of air and thus preventing air infiltration and thus causing temperature differences. They can work with heaters or air conditioners as per the requirement. The air curtains generally employed are downward-facing ones. Upward-facing or side-facing options are also available.
People also use air curtains to avoid cold drafts by mixing warm air from air curtains with heating functions in cold countries. The fan is powerful enough to generate a jet of air that can reach the ground.

Also, due to their high air turbulence against the ground, they help ward off flies, mosquitoes, and other insects. An air curtain door also can form an invisible isolation wall to prevent dust and odors from outdoors.

Air curtains are energy-saving products, they can help reduce power expenditure by improving air conditioner or air heater efficiency. An Air curtain door has a small power consumption and can create an effective air wall to isolate air between indoors and outdoors. Some air curtains also use DC motors, which have smaller power consumption.
Industrial and commercial applications may vary with requirements.

The Air curtain is NOT an air conditioner. An Air curtain door is a powerful fan that forces a high-speed air stream over the entrance to isolate the interior and exterior air environment. It consumes less energy than an air conditioner. People install air curtains widely at the entrance doors/gates of supermarkets, theaters, hotels, food storage warehouses, residential, etc. It keeps the flying insects out and keeps conditioned air inside, reducing energy costs.
