Air Curtain FAQ

Air curtains, or air blades, are devices installed near doors and gates to separate the indoor climate from the outdoor climate. They are primarily used in industrial environments such as factories, warehouses, railway workshops, retail stores, and public buildings. Since doors often remain open for the transit of people and work vehicles, air curtains help prevent temperature fluctuations and reduce energy consumption of climate control systems.

Air blades provide valuable support to climate control systems by creating an effective barrier to the external environment. Positioned near gates, 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 bottom of the opening. This barrier significantly reduces heat loss and allows personnel near the gates to work without experiencing the negative effects of temperature fluctuations or drafts.

Industrial air curtains are highly effective at reducing heat loss: they can retain up to 70-80% of heat in winter and maintain cool air in summer, creating an invisible separation between indoor and outdoor environments. This means fewer temperature fluctuations, greater comfort for those working near openings, and significant energy savings on heating and cooling systems. Effectiveness depends on door height, the type of curtain selected, and proper installation, but under ideal conditions the benefit is immediately noticeable.

Installation height is a key factor in ensuring air curtain effectiveness. In industrial settings, the most high-performance models can cover openings up to 5-6 meters in height while maintaining a continuous and well-distributed air flow. For larger openings, modular solutions or high-power air curtains can be implemented. The selection of the right size must be based on the opening characteristics (height, width, traffic intensity) to ensure optimal retention of the indoor microclimate.

Sizing an industrial air curtain is based on several fundamental parameters: opening width and height, door opening frequency, and environmental conditions (indoor/outdoor). Generally, the curtain must fully cover the passage width and have sufficient power to generate a continuous air flow to the ground without dispersion. For very tall doors or environments with strong air currents, high-pressure centrifugal models are preferred, as they are better suited to ensure separation between the two environments. Proper sizing enables maximum energy efficiency and comfort, avoiding waste and reducing operating costs.
