Air curtain principle and classification

Firstly, let's talk about the principle behind an air curtain machine. This device utilizes a specially designed high-speed motor that powers a cross-flow, centrifugal, or axial-flow fan. Together, they generate a strong air barrier that efficiently separates indoor and outdoor air environments. By doing so, it helps maintain clean indoor air, prevents the loss of heated or cooled air, reduces energy consumption for air conditioning systems, and blocks out dust, insects, and harmful gases. Air curtain machines are commonly installed at entrances and exits in various locations such as factories, stores, restaurants, cold storage facilities, hotels, airports, train stations, and any place where air conditioning is used, providing users with a comfortable working, shopping, or leisure experience.

Secondly, air curtain machines can be categorized in several ways. Based on their functional use, they are divided into natural wind models and those with cooling and heating capabilities. For the latter, options include water-heated and electrically heated air curtains. In terms of motor and fan design, air curtain machines can be classified as cross-flow, axial-flow, or centrifugal types. When considering the diameter of the fan blades, sizes range from 90mm to 150mm, with larger fans producing greater airflow volumes. Depending on the intended installation height, air curtain machines are available for heights ranging from 2.5 meters to over 5 meters, such as 125cm, 150cm, 200cm, 250cm, 300cm, 450cm, etc. Additionally, based on the length of the unit’s body, air curtain machines come in lengths like 900mm, 1000mm, 1200mm, 1500mm, and 1800mm.

These machines play a crucial role in enhancing comfort while saving energy and maintaining hygiene. Whether you're looking to keep your space cool in summer or warm in winter, an air curtain machine tailored to your specific needs can make a significant difference. For example, businesses aiming to conserve energy and improve customer satisfaction often opt for these devices. They not only help control temperature but also reduce noise levels by sealing off open doorways. Furthermore, some advanced models even feature programmable settings allowing users to customize operation times and speeds according to their preferences.
