What Is An Air curtain?

Air curtains are usually installed above the doors of halls and high-traffic buildings such as restaurants, shopping centers, malls, etc., where numerous people pass every day. Due to the frequent opening and closing of doors, these places are constantly exposed to dust, cold, heat, and insects, which increases the energy consumption required for cooling or heating.
To avoid these problems, devices called Air Curtains are used. Their benefits and applications, as well as the purpose of an air curtain, installation methods, and curtain use, their benefits and applications, as well as what is the purpose of an air curtain, installation methods, and also some air curtain heating and cooling systems. We will also mention well-known air curtain companies and air curtain suppliers.

What is an Air Curtain?

An air curtain is an HVAC and MEP electrical device installed above doors to create an invisible barrier of air, preventing the loss of heating or cooling and blocking dust and insects. It improves energy efficiency and maintains a clean, comfortable indoor environment. Air curtain use in factories and commercial buildings has become one of the most practical solutions for energy-saving and hygiene control. That is why air curtains are getting more and more popular among HVAC engineers.

How Air Curtain Devices Work

The air curtain works automatically when the door is opened, blowing a pressurized stream of warm, cool, or temperate air from top to bottom to separate the indoor from the outdoor environment. The system is composed of a body, motor, and a powerful fan that constantly pushes air vertically downwards. This prevents outside air, dust, or insects from entering. Overall, the air curtain purpose is to act as a protective barrier at the entrance, with efficiency ranging from 60% to 80%.

Types of Air Curtain Devices

Air curtains can be categorized by installation type: vertical (top-down), vertical (bottom-up), and horizontal. The vertical top-down type is the most common due to easy installation and higher thermodynamic efficiency.

Air Curtains for Offices and Commercial Spaces

This category is used in offices, restaurants, malls, and shops. They are designed with an elegant look to match interior spaces and often come in white, black, or stainless steel. These models can also include heating coils for air curtain heating and cooling in the winter.

Industrial Air Curtains

Industrial air curtains are designed for factories and facilities with large doors. They are customized based on motor power, air pressure, temperature difference, and installation height. Due to high airflow fans, they usually require three-phase electricity. They are available as cooling-only or air curtain heating and cooling models.

Air Curtain Installation Method

The air curtain must be installed horizontally above the entrance, firmly fixed to avoid vibrations. In case of obstacles like windows above the door, metal structures can be used for mounting. For industrial models, ensure that a three-phase power supply is available.

Air Curtain Applications

Applying an air curtain above the doorway of crowded spaces is always a wise way of preventing energy loss. Here are the most frequent applications of air curtains:

• Food, dairy, and pharmaceutical factories
• Shopping centers and supermarkets
• Cold storage and warehouses
• Restaurants and large kitchens
• Office buildings, banks, and museums
• Hotels, malls, airports
• Hospitals

Tips for Air Curtain Use

Following the tips below helps you make the best use of air curtains:

• The efficiency of an air curtain depends on the pressure difference between inside and outside.
• Air curtain heating and cooling systems can be integrated for winter use.
• The best performance is achieved with vertical downward airflow and powerful fans.

Benefits of Air Curtain Devices

Using any type of air curtains includes many benefits; the boldest of which are:

• Energy saving: The purpose of an air curtain is to prevent energy loss during door openings.
• Insect prevention: Keeps indoor areas hygienic and free of insects.
