Where are the special-shaped air curtains generally used?

There are also some occasions that are difficult for ordinary air curtains to achieve, but in order to better pursue the effect of thermal insulation and energy saving, some special air curtains will be customized according to the actual situation, such as:

1. The arc door air curtain machine applied to the revolving door, and the color and material of the air curtain machine can be changed according to the needs of the actual environment.

2. Since many automatic door heads have been installed with induction devices, it is impossible to install air curtains, so induction door air curtains of different lengths can be specially formulated for such on-site environments.

3. The elevator air curtain machine is an air curtain machine specially used for the elevator door.

Why is the air curtain machine able to save energy?

Create a comfortable indoor environment: The air curtain machine generates high-speed airflow, divides the indoor and outdoor into two independent temperature zones, maintains the effect of indoor air conditioning and air purification, saves electricity while promoting air circulation and making the air fresher. Effectively isolates microorganisms such as dust, smoke, odor and insects.

Prevent the outflow of cold and warm air and save electricity: the continuously formed air door can effectively prevent the leakage of cold (warm) air and save electricity. The indoor and outdoor are divided into two independent temperature zones, which maintains the effect of indoor air conditioning and air purification, and saves electricity. At the same time, it promotes air circulation to adjust the temperature, and achieves the purpose of saving energy and improving the environment.

What are the precautions for the use of air curtains?

(1) Read the instruction manual carefully before use, and fully grasp the structure, performance, installation, use and maintenance methods and precautions of the air curtain.

(2) Once a problem with the fan is found, it should be stopped immediately for inspection.

(3) Regularly remove foreign objects in the front and rear pipes of the fan to prevent accidents. The lubricating grease of the transmission part should be replaced regularly, and rain-proof measures should be taken in the open air.

(4) When the weather conditions change, the valve should be used to adjust the air volume.

(5) Regularly measure the current of the fan motor. Under normal circumstances, the measured current should be less than the rated current.

(6) Due to the particularity of the air curtain, the noise of the new fan will be louder, and a one-week break-in period is required.
