Meduim-Pressure Axial Smoke Extraction Fans –
B AMD F300/F400
Installation and Operating Instructions
Connection of smoke extraction ducts with mounting accessories:
–
Flexible connectors
Flexible connectors (elastic sleeves) STSB... F400 must be used for the intake and/or outlet-side connection of smoke
extraction fans to smoke extraction ducts. When mounting the flexible connectors, it must be ensured that the installati-
on gap 145 mm is maintained and this prevents tension load or compression load. Do not mount the elastic connectors
so that they are staggered. This will prevent performance reduction and noise generation.
– Extension duct
When installing in duct sections, it must be ensured that there is a sufficiently long straight duct section 2.5 x D before
and after the the fan 2.5 x D (e.g. with extension duct VR...), as otherwise significant performance reductions and noise
generation can be expected.
– Vibration dampers
In order to prevent the transmission of vibrations, the use of steel spring/vibration dampers SDD 1F 4-10 and SDZ
1F 4-9 is recommended. The arrangement of attenuators, mounting brackets and dvibration dampers can be seen in
Fig. 6-9.
– Attenuator
Figure 9: Duct installation with intake and outlet-side attenuators RSD... F400 with mounting brackets MK. The inta-
ke-side attenuator must be mounted at the inlet, and the outlet-side attenuator on the outlet together with the flexible
connectors.

Backdraught shutter
Automatic backdraught shutter RVS... F400 with spring reset:
Horizontal installation possible in any direction, vertical installation possible with upward flow.
