Type KD flexible joint
features a laminar design; it is terminated with a flange with the holes sized and spaced as on the mating
component flange. The special fibreglass silicate textile ensure durability at 400ºC for 120 min or at
600ºC for 60 min.
Type KD flexible joint is used to eliminate the vibrations transmitted from the fan to the ventilation
system. It acts as a vibration damper. It is also used to compensate for thermal elongation. The fan
integrated in a ventilation system should feature the flexible joint on the suction side.
