Straight Through, Absorptive
Design:
Expected Attenuation of High
Frequency Noise is 20 dBA
Straight through design with no center panel offers
good attenuation of high frequency noise with low
pressure drop. Use for small atmospheric vent
applications, on blower or compressor intakes and
discharges, and as an add-on to boost overall
attenuation when
installed in series with an M-line chamber type
silencer. Use FP model for intake service; FPE model
for exhaust service
