Industrial air curtains
Air curtains for industrial doors guarantee maximum energy efficiency, reducing heat loss and improving the comfort of work environments. Ideal for sheds, warehouses, and logistics areas, they create a true “invisible door” that separates zones with different temperatures, maintaining constant internal conditions and optimizing consumption.
What air curtains are and what they are used for
Air curtains – also known as air blades – are devices that, when installed near doors and gateways, allow for the separation of the indoor climate from the outdoor one.
They are mainly used within large industrial environments such as factories, logistics warehouses, railway workshops, commercial businesses, and public buildings. These are places where entrance doors and gateways often remain open to allow the transit of work vehicles and people.
In these cases, the constant opening of these passages, even for prolonged periods, can lead to significant thermal imbalances in the internal environment, with a consequent increase in system consumption, as they must work harder to maintain a comfortable internal temperature.
How do air curtains work?
Air blades represent a valuable support to the system, as they create a true barrier towards the external environment.
The air curtain is positioned near the doors to prevent the entry of air and/or dirt (pollen, sand, etc.) into the work environment. Depending on the chosen model, the air flow can come from the top of the opening or from the bottom.
By creating a true shield, the air curtain allows for a drastic reduction in heat loss and also enables personnel located near the doors to work peacefully, without perceiving annoying thermal fluctuations and harmful drafts.
Advantages of industrial air curtains
SAVINGS
In winter, they block the entry of cold air, preventing the heating system from intervening to balance the thermal imbalance.
HEALTH
They safeguard health without annoying and harmful air infiltrations from the outside. They protect against the entry of smog, dust, and insects into the environment.
THERMAL COMFORT
Air curtains allow for a uniform room temperature to be maintained for a comfortable work environment.
RESISTANCE
Bottom-up air blades are designed to withstand the passage of heavy loads. The components used are of premium quality.
VERSATILITY
The spaces near the doors are completely available for working in comfort and safety.
ease of installation
Air curtains are simple to install and can be positioned above or to the side of the doors.
Industrial air curtains:
comfort and energy savings
In industrial sheds, where the continuous passage of goods, vehicles, and people requires frequent door openings, industrial air curtains play a fundamental role in reducing heat loss and improving the energy efficiency of heating or cooling systems.
By creating an invisible “air blade,” these solutions separate the internal environment from the external one, preventing the escape of treated air and the entry of cold drafts, dust, exhaust gases, or insects.
The result is greater comfort for operators working in loading and unloading areas or near openings, ensuring healthier and more constant working conditions throughout the year, even during the coldest periods.
Air curtains therefore represent a smart choice for those who want to optimize energy consumption without sacrificing productivity and staff well-being.
Who it is for
Industrial
Industrial sheds require safe workplaces protected from external air for the psychophysical well-being of their collaborators. The logistics sector, in particular, is characterized by warehouses with numerous doors. Near these openings, workers need to be protected from external drafts to work safely.
Railway
In the railway sector, particularly in workshops dedicated to train maintenance, it is essential to ensure an environment well-insulated from drafts to avoid heat loss. Air curtains can be configured with specific solutions to allow the passage of tracks without compromising the effectiveness of the system.
Aviation
In the aviation sector, hangars intended for aircraft maintenance require maximum control of internal conditions, even with large doors frequently open. Air curtains guarantee the separation between the external and internal environment, limiting heat loss and maintaining comfort and safety for technical personnel.

Air curtain FAQs
In this section, we answer the most common questions about industrial air curtains: what they are, how they work, how effective they are, and how to size them correctly based on the characteristics of the shed.
Air curtains, or air blades, are devices installed near doors and gateways to separate the indoor climate from the outdoor one. They are mainly used in industrial environments such as factories, warehouses, railway workshops, shops, and public buildings. Since doors often remain open for the transit of people and work vehicles, air curtains help avoid thermal fluctuations and reduce the energy consumption of climate control systems.
Air blades are a valid support for the climate control system, as they create an effective barrier towards the external environment. Positioned near the doors, they prevent the entry of air and dirt into the work environment. Depending on the model, the air flow can come from the top or the bottom of the opening. This barrier significantly reduces heat loss and allows personnel near the doors to work without suffering the negative effects of thermal fluctuations or drafts.
Industrial air curtains are very effective at reducing heat loss: they can retain up to 70-80% of the heat in winter and maintain the cool air in summer, creating an invisible separation between inside and outside. This means fewer temperature fluctuations, greater comfort for those working near openings, and significant energy savings on heating and cooling systems. Effectiveness depends on the height of the door, the type of curtain chosen, and correct installation, but under ideal conditions, the benefit is immediately perceptible.
Installation height is a key factor in ensuring the effectiveness of the air curtain. In industrial settings, the highest-performing models can cover openings up to 5-6 meters high, while still maintaining a continuous and well-distributed air flow. For wider openings, modular solutions or high-power air curtains can be provided. The choice of the right size must be made based on the characteristics of the opening (height, width, traffic intensity) to ensure optimal maintenance of the internal microclimate.
The sizing of an industrial air curtain is based on some fundamental parameters: width and height of the opening, frequency of door opening, and environmental conditions (indoor/outdoor). In general, the curtain must cover the entire width of the passage and have sufficient power to generate a continuous air flow down to the ground, without dispersion. For very high doors or in environments with strong drafts, high-pressure centrifugal models are preferred, as they are better suited to ensuring separation between the two environments. Correct sizing allows for maximum energy efficiency and comfort, avoiding waste and reducing management costs.
