The silencer is used for attenuation of the operation noise generated by ventilation equipment and spreaded in the air ducts. Designed for connection to round air ducts. To complete the VDO fans, it is necessary to use SR...400/2 silencers, which are designed to operate at a temperature of 400 °C for 2 hours.
The casing of the SR silencer made of steel is filled with sound-absorbing material with a protective covering (against fiber blowing).
