Wind deflector

A wind deflector for a smoke ventilation system can sometimes be a legal requirement. It helps to dissipate smoke even when wind conditions aren’t ideal. Therefore, it reduces the risk of occupants of the building inhaling smoke in the event of a fire.

The wind detector allows you to comply with aerodynamic smoke ventilation requirements or geometrical area requirements.

Measurements:

• Geometrical opening area, Av [m2]
• Aerodynamic area with wind deflector (KWU) , Aa [m2]

Applications:

• The KAS smoke ventilation window, without a wind deflector, is used when the only legal requirement is geometrical area
• The KWU wind deflector should be used when an aerodynamic free area is legally required. This may depend on the application and the local legislation.
