Key Features of Olefini Air Curtains

What they are: Air curtains are fan-powered devices installed above door openings that produce a directed stream of air. This “invisible air barrier” helps separate indoor and outdoor spaces without a physical door, reducing heat/cold loss and preventing insects, dust and pollutants from entering while doors are open.

Typical uses:

• Retail entrances, supermarkets, hotel lobbies

• Restaurants and cafés

• Warehouses and industrial buildings

• Hospitals and public buildings

Construction and performance (varies by model):

• Plastic or metal housing: Many Olefini units use plastic shells for lightweight economy variants; others use metal for durability.

• Airflow & barrier: Units provide airflow rates typically from ~1,400 to ~3,800 m³/h depending on model and width.

• Coverage: Designed for door heights ~2.5–3.0 m with widths matched to model lengths (e.g., 1.0-2.0 m).

• Energy & climate: Helps maintain indoor temperature by reducing uncontrolled exchange with outside air.
