Discharge Silencers

Discharge Silencers

 Rotary positive displacement blowers discharge the air in slugs that have been compressed by the line pressure. These slugs can be highly destructive to equipment downstream of the blower. Discharge Silencers are necessary to reduce these pulsations. Discharge Silencers also serve to smooth out the air flow for proper use in the system. Without Discharge Silencers the pulsations can vary anywhere from 40% to 80% of the absolute line pressure. With properly selected and sized Discharge Silencers the fluctuation will be no more than one to two percent of the absolute line pressure.

Discharge Silencers should be located as close to the blower as possible. If you have questions about the silencer’s location contact the factory.
