Prevent the transmission of vibrations and compensate the ductwork length variations due to thermal expansion. With a metal support on both sides.
Operating temperature: from ≈ -30°C up to ≈ +70°C
Quantities: 25 m per carton
The flexible round duct connections prevent the spreading of vibrations and noise. They also act as compensators when the lengths of the air-ducts vary (steel expansion related to temperature fluctuations).
