Mounting Flange

Between the two flange rings, the ZD-DF damper has a layer of vulcanized-on rubber for suppressing body-borne sound, which can be reduced by approx. 3-10 dB(A), depending on the frequency. Owing to the different sound velocity of steel/air/rubber (5000/331/50 m/s) as well as its damping oscillation tendency, the  ZD-DF...  damper provides a low-cost noise damping solution.
