The flexible insert for rectangular duct type D-HVP is developed to absorb mechanical vibrations generated by the fan in the duct ventilation system when moving the air medium.
The construction of the flexible insert is based on a housing consisting of two flanges connected by an insulating material that ensures the tightness of the channel. The flanges of the flexible inserts are made of a special galvanized steel profile.
