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. Choose an FP model for intake service or an FPE for exhast service.
