Flexible inserts carry out function of vibroclearing and are intended for absorption of mechanical oscillations and prevention of distribution of vibration noise of separate elements of the working equipment (fans) on air ducts on all ventilating system, and also for partial compensation of temperature deformation in the route of an air duct, and are applied in the ventilating installations moving air in the range of temperatures from −40 with °C to +80 °C. Flexible inserts also serve for providing a tight flexible joint which maintains a high pressure and abrasive is steady. The case of an insert is manufactured of galvanized steel, the fabric tape (a neoprene, blamed) providing tightness of the channel is fixed in the middle. The design of an insert allows to fix it to elements of ventilating systems on flange, rack or nippelny or connection.
