Intake Silencers

Since the inlet to a rotary positive displacement blower it is open to the surrounding environment, Intake Silencers are necessary to reduce the air borne noise the blower generates. As the blower impellers rotate air is sucked into the blower. The frequency of these slugs of air being generated is determined by the speed and number of lobes on the impellors. Intake Silencers serve to smooth out these slugs of air and reduce the noise emanating from the blower inlet.

Many users believe that an Intake Filter Silencer – such as Stoddard Silencers’ F64 – eliminates the need for an Intake Silencer. This may be true for smaller blowers; however, as the blowers increase in size the need for an Intake Silencer becomes very apparent. If you have questions contact the factory.
