Fan Accessories - Vibration Damping
- Made in EPDM rubber and s/steel screws
- Excellent vibration resistance
- Available in all types of axial rangers
Vibrations damping rings are flexible items built in a special rubber (EPDM )for vibration absorption. They are mounted between the blower flange and the plant
pipe (or fixing surface) to avoid the transmission of noise and vibrations when the blowers are in operation. These items are fixed by screw placed on both sides of the ring realising a flexible but stable fixing. The elastic ring absorbs all vibrations by converting movement energy into deformation work, in that way they reduces noise and lengthen the life of the equipments installed.

Fan Accessories - Clindrical silencer for axial blowers
- Made to reduce noise level in the engine room- Available in "ogive " version for a better noise reduction
Silencers are system that allows the passage of airflow while simultaneously facilitating reduction to the passage of sound (or noise) in “air moving” applications such as air conditioning or ventilation system, dust control equipment, motor cooling fans.
Cylindrical attenuators are designed mainly for use with axial flow fans however they can also be adapted for ducted applications.
The attenuators are insulated by acoustic infill and, for Cb series, a central-pod is placed in the silencer for higher attenuation.
The silencers are supplied at a parity of DN (Nominal Diameter) in three lengths named 10,15 and 20 that express the ratios between length an nominal diameter.
Standard silencers are suitable for temperatures from -40°C to +200°C.
