Operation and Maintenance Documentation GUARD v202301
1. PURPOSE OF THE DEVICE
The air curtain is intended to be used in regions with a moderate and cold climate, in spaces where the temperature ranges
from -10 to +40°C, in conditions free from external factors such as pollens and hydrometeor (horizontal precipitation).
In winter, air curtains protect against heat loss in rooms by directing an airstream across the entrance and preventing cold air
from entering the heated space. In summer, the curtains may be used as cooling devices preventing the entry of hot air and
pollutants from outside.
The GUARD air curtains are designed to protect against heat losses in buildings of medium and high capacity and with a
required mounting height of 4 m such as:
supermarkets, large retail spaces,
car showrooms and service stations,
sports and show halls,
exhibition surfaces
