It is a customized air curtain unit for integration for automatic revolving doors.Even using a revolving door, the cold air and insect can still get in at every rotation.So a revolving air curtain is required. it helps to reduce energy costs by preventing the loss of conditioned air and prevent the entry of outdoor air, dust, and pollutants, at the same time maintaining a consistent indoor temperature.It normally used in high-traffic areas, such as airports, hotels, and office buildings.

How a revolving door air curtain works

A revolving door air curtain works by creating a barrier of high-velocity air that separates the indoor and outdoor environments. The air curtain is installed above the entrance of the revolving door and uses a combination of fans and air ducts to generate the high-velocity air stream. This helps to prevent the entry of outdoor air, pollutants, and insects, while maintaining a consistent indoor temperature.

What is the main parts of revolving door air curtain?

Blower motor: The blower motor is responsible for powering the fans that create the high-velocity air stream. It is typically located inside the air curtain housing and is controlled by an electrical switch or thermostat.

Air ducts: The air ducts are responsible for directing the airflow from the blower motor into the high-velocity air stream. They are typically made of metal or plastic and are designed to withstand the force of the airflow.

Air outlet: The air outlet is the area where the high-velocity air stream exits the air curtain and creates the barrier. It is typically located above the entrance of the revolving door and is designed to cover the entire doorway.

Control panel: The control panel is responsible for regulating the operation of the air curtain, including fan speed, temperature control, and power settings. It can be accessed through a digital display or manual switches.

Housing: The housing is the outer casing of the air curtain and is designed to protect the internal components from damage. It is typically made of metal or plastic and can be customized to match the decor of the building.

They are particularly useful in areas where there is a need for temperature control or to prevent the entry of airborne contaminants.

There are several different types of revolving door air curtains available, including heated and unheated models, as well as models with adjustable speed settings. Some models also come with additional features, such as remote controls and sensors that automatically activate the air curtain when the revolving door is in use.

What is the common failures of revolving door air curtain

While air curtains are generally reliable and low-maintenance, there are a few common failures that can occur over time. These include:

Motor failure: The motor in an air curtain can fail over time due to wear and tear, lack of lubrication, or electrical issues. This can result in reduced airflow or a complete loss of function.

Blower wheel damage: The blower wheel is responsible for moving air through the air curtain, and can become damaged or warped over time. This can lead to reduced airflow or noisy operation.

Electrical issues: Air curtains rely on electrical components to operate, and these components can fail due to power surges, wiring issues, or other electrical problems.

Thermostat failure: The thermostat in an air curtain is responsible for regulating the temperature of the air stream. If the thermostat fails, it can result in inconsistent temperatures or a complete loss of temperature control.

Blockages: Over time, air curtains can become clogged with dirt, dust, and debris, which can obstruct airflow and reduce performance. Regular cleaning and maintenance can help to prevent this issue.

To avoid these common failures, it is important to perform regular maintenance on your air curtain, including cleaning, lubrication, and inspection of all electrical components. Additionally, it is important to choose a high-quality air curtain from a reputable manufacturer, and to have it installed by a professional to ensure proper operation.
