Air curtains have become essential in modern buildings, whether shops, offices, workshops, or warehouses. Their role is to create an invisible curtain of air at the entrance to a room in order to separate two thermal environments without blocking the passage. This technology maintains indoor thermal comfort while reducing energy losses associated with frequent door opening.

What is an air curtain?

An air curtain blows a steady, uniform stream of air across the entire width of an opening. This stream forms a barrier between the indoor and outdoor air, preventing cold or hot drafts, dust, insects, and odors from entering the building.
Used in both winter and summer, air curtains help improve occupant comfort and optimize the energy efficiency of heating and air conditioning systems.

The key role of the fan in the air curtain

The fan is the heart of the system. It generates the continuous air flow needed to create the protective barrier. The stability, speed, and regularity of the air jet depend directly on the quality and size of the integrated fan. A high-performance fan guarantees a uniform, effective, and quiet air curtain—three essential criteria in commercial and industrial applications. 

ECOFIT double-inlet centrifugal fans: the ideal solution

ECOFIT double inlet centrifugal fans are particularly suitable for air curtains. Thanks to their forward curved blade design, they offer high air flow with suitable pressure, while maintaining a low noise level. Their double inlet configuration allows for better flow distribution and optimal compactness, ideal for air curtains installed in confined spaces.

ECOFIT products stand out for:

• their quality, proven robustness, and long service life,
• optimized airflow performance,
• controlled energy consumption thanks to EC technology,
• and easy integration into air curtain systems, whether heated or unheated.

 

Technology that promotes comfort and protects the environment

By combining high-performance airflow design with an energy-efficient motor, ECOFIT fans directly contribute to reducing operating costs and limiting the carbon footprint of buildings.
Their effectiveness ensures good thermal insulation, even when there are significant differences in temperature or pressure between two areas.
ECOFIT, a recognized specialist in industrial and commercial ventilation, offers a complete range of AC and EC double inlet centrifugal fans designed for air curtains, combining performance, reliability, and energy efficiency. With ECOFIT, every air flow becomes a sustainable solution for thermal comfort and energy efficiency.
