The air curtain machine can prevent dust and insects. The air curtain machine produces high-speed airflow and forms a protective door, which can effectively block the invasion of outdoor dust and flying insects and keep the room clean.

Is the higher the wind speed of the air curtain the better?

At present, most of the air curtains sold in the market have a wind speed of 10-20m/s at the outlet. However, it is not that the higher the wind speed, the better the partition effect of the air curtain.

If the wind speed is too large, it will rebound after hitting the ground, causing the airflow to be chaotic, thus affecting the partition effect of the air curtain on the indoor and outdoor air.

Therefore, in order to avoid the misunderstanding of the selection, we should select it according to the specific door height and in combination with the specific environment.

In addition, if we find that the wind speed of touching the ground does not meet the requirements in our actual work, a more practical method is to reduce the height of the door lintel.

The study pointed out that the relationship between the wind speed and the voltage of the air curtain machine shows that to stably output the maximum wind speed, the voltage needs to be controlled above 175 volts. Therefore, in daily work, we need to determine whether the voltage of the enterprise is stable above 175 volts.

Some air curtains with high wind speed require higher power, and some need to be equipped with 380 volts of industrial voltage, which needs to be confirmed with the manufacturer in advance during installation.              

What is the difference between the power consumption of the air curtain and the air conditioner?

The hot air curtain machine is indeed a high-power-consuming electrical appliance. The standard heating power of an ordinary 1.5-meter hot air curtain machine is 20kw, which means that it consumes 20 kWh of electricity per hour.

For a 1.5-horsepower air conditioner, the rated heating power is 1.102kw, if the compressor runs continuously. In contrast, the power consumption of the hot air curtain is even more alarming. The air curtain machine and the air conditioner are used together organically to achieve the ideal temperature effect.

Where can we see air curtains in life?

Generally, there is an air curtain at the door of the supermarket, which is to blow air from the top of the door frame, because the door of the supermarket cannot be closed, and the air conditioner must be turned on to prevent the outside air from entering, and also to prevent the air conditioner from running out. By blowing the air to form an air curtain to play the role of isolation.

In general public places, the doors cannot be closed and the air-conditioning must be used.

Guangzhou Meihao HVAC Equipment Co. Ltd. would like to appreciate for the trust and support from clients. From 1982 our first air curtain model came out to 2019, Meihao air curtains have been used in hundreds of construction projects.
