Smoke exhaust roof fans F400/F600 – B VD
The roof fan attenuator B HSDV has four mounted eyebolts for all sizes as standard.
If necessary, these eyebolts on the fan and roof fan attenuator can be used for on-site anchoring under high wind
loads. The need for on-site anchoring must be checked in individual cases depending on the local wind influences.
The installer must anchor the fan at the provided anchor points if such environmental influences are expected. The wind
load should be calculated according to DIN EN 1991-1-4.
