S.air specializes in the conception of smoke evacuation systems for underground parking lots.

Due to the increasing use of cars, closed parking buildings are increasingly being used in places where many people come together, such as shopping centers, office and residential complexes, etc.

The newest building forms are increasingly having problems applying existing ventilation techniques for ventilating parking garages.

In the past, these were mostly ventilated using airducts.

The disadvantage of this system was:

• Compartmentation
• Dead corners
• No controlled smoke exhaust
• High energy consumption
• Loss of parking space

Since the introduction of the NBN S 21-208-2, thrust ventilation has become a fixed fact that can serve as a solution to provide maximum security to your parking lot without major interventions.

Meanwhile, the tunnel ventilation technique has been used extensively for ventilating parking garages. In this ventilation system, thrust fans are used. The technique is based on the thrust principle.
