Non-insulated flexible duct
Flexible ventilation duct composed of a 65-micron thick PVC film
Fields of application
The non-insulated flexible duct is designed to convey air downstream of the heat recovery unit to the air distribution manifolds (when the temperature of the space being crossed is not so low as to produce condensation). The non-insulated flexible duct can be installed inside walls or on the ceiling but is not suitable for burial. For installation in unheated spaces, it is recommended to use insulated ventilation ducts (codes VBNSxx). The non-insulated flexible duct is available in various diameters to connect to all Ideal Clima heat recovery units.
