Avoid resonance frequencies
Important
Risk of damage to the fan due to resonance frequencies
♦ The minimum fan speed should be double the resonance frequency of the anti-vibration system
(vibration dampers).
♦ To avoid resonance frequencies, see 8.3 Frequency converter (if used), page 21.
7.1 Vibration dampers
Important
Risk of damage to the fan due to incorrect vibration dampers
♦ Use the vibration dampers suitable for the respective weight.
♦ Use the vibration dampers with fire resistance classes that match the respective application.
Sylodyn vibration kit (if used)
The responsibility for the Sylodyn vibration kit installation is with the buyer/installer.
Important
Risk of damage to the fan due to incorrect installed vibration dampers
♦ The fan shall rest entirely on the sylodyn anti vibration blocks. It is important that the fan is not pressed
against the mounting frame, therefore the minimum distance of 15 mm has to be kept, see following
picture.
