Application

Flexible round silencers of the CF series are designed to reduce noise in air conditioning systems with round air ducts
To reduce the noise level generated by the air flow in air flow regulators of the LVC and TVR series, as well as in mechanical regulators of the RN and VFC series
To reduce the noise generated by the fan
These devices can be used to reduce the level of noise transmitted through air ducts to an adjacent room
