The COMBIFLEX flexible duct is made of multilayer aluminium, tightly covered with non-flammable 110 micron PVC jacket. It’s construction is reinforced with spiral steel spring wire.
No vapour condensation is an advantage of this type of ducts. Moreover the COMBIFLEX duct can be cleaned easily, is resistant to chemicals and UV radiation. The COMBIFLEX flexible ducts are recommended for ventilation and air-conditioning systems as well as for heating
Packaging: 10 m sections packed in cardboard boxes
Temperature Range -30 °C / +150 °C
Air Velocity 30 m/s (max)
Operating Pressure 3000 Pa (max)
Degree of flexibility (winding diameter): relative to a specific diameter i.e. ca. 0,6 x diameter in mm.
Allowable negative pressure: depending on duct position.
In straight sections 1/3 of transmitted pressure per the specific diameter can be assumed.
