The WING air curtain has been designed to prevent uncontrolled air migration through the building entrances and between its separated internal zones. By creating invisible barrier it stops dust, smells and insects helping to keep required air quality in each of the zones, even when the door between them is open. The WING is best anywhere where your door need to be open like: warehouses, shopping malls, restaurants, hotels, hospitals, schools, airports, sports halls and stadiums, beauty salons, workshops, joineries and churches.
