The Dalap ALITSONO flexible air duct with a diameter of 100 to 250 mm (4–10 inch) and length of 5 to 10 m is thermally insulated & sound-absorbing, making it ideally suited for locations with increased noise protection requirements, such as education centres, kindergartens, hospitals or spa centres. The insulated aluminium flex duct is used, for example, as a connection to ventilation systems such as kitchen extractor hoods, heat recovery units or air conditioning systems.
The Dalap ALITSONO air duct consists of microperforated, polyester-laminated aluminium foil, reinforced with a spring spiral made of carbon steel and a 25 mm thick insulation layer of mineral wool. Suitable for temperatures from -30 °C to +140 °C, with a velocity of 30 m/s and pressure of 2500 Pa.
