Flexible air duct

polyesterthermally-insulated

Flexible duct connection, with thermal-acoustic insulation.A simpel and easy connection between the unit and distribution manifolds. Is also useable between the unit and discharge air and outdoor air intake. The perforated internal duct allows the insulating layer to damp and absorb the noise created in ventilation units. A protection film covers the insulating mat to avoid its erosion. Furthermore it limits the thermal exchange between the carried air and the external environment and avoids the formation of condensate during cooling.
