Flexible inserts are designed to prevent the transmission of vibrations.
Flexible inserts are designed to prevent the transmission of vibrations from the fan to the ducts and to provide a tight flexible joint that can withstand high pressure. Flexible inserts must not be used as a support structure when installed in a system to avoid failure due to excessive mechanical stress. Two flanges made of galvanised steel sheet connected by a PVC flexible hose. Mounting in any position.
