Silencers for Maximum Noise Reduction
Each silencer reduces noises differently. The larger the size, the higher the reduction. These reductions range from 34.9dB to 48.4dB. This document gives these combined reductions as well as reductions at various frequencies.
Both the SP and SP-S Silencer are designed to take high inlet velocities of 900fps, so they make excellent exhaust silencers. The acousitcal material ‘Dalcon’ is rated for 1,250°F so that this silencer works well on steam conditions. The SP and SP-S exhaust silencers have the same quality of workmakship that has gone into all Penn Products for so many years and is guaranteed for a year against defects in materials or workmanship.
For maximum noise reduction, choose Penn’s SP Exhaust Silencer.
