BEL Exhaust Silencers come in three different models:

• Multi-Chamber Reactive Type (Primary Silencer)
Model : BEXP-S (side entry) &
BEXP-E (end entry)
BEL Primary silencers provide good attenuation at mid and low frequencies. They are available with side entry (BEXP-S) and end entry (BEXPE). Oveall attenuation is approximately 30 dB.

• Straight Through Absorptive Type (Secondary Silencer)
Model : BEXS-E (end entry)
BEL Secondary Silencers are connected in series with the primary silencers and provide effective attenuation over a broad range of frequency due to the presence of high temperature sound absorbing acoustic insulation inside the internal side of the silencer. Overall sound attenuation is approximately 20dB.

• Supercritical Type (Combination Type)
Model : BEXC-S (side entry)
BEXC-E (end entry)
Supercritical Exhaust Silencer is a compact combination of reactive type and absorptive type exhaust silencer. Normally used when space is limited and noise criteria is not too stringent. Overall sound attenuation is approximately 35dB.
