Flexible Aluminium Air Duct diam. 100-200 mm

Aluminum hoses are highly flexible and can be easily bent, so there is no need to install elbows. They are available in single-layer or double-layer versions with 25 mm thick insulation. Pipe dimensions are selected based on the volume of air flow, i.e., the size of the heat recovery unit. Sheet metal fittings are used to connect individual branches. The duct is slid onto the fitting and secured with cable ties or adhesive tape.
