FPS-FPSE Full Flow Internal Center Panel Absortive Design

FPS-FPSE Full Flow Internal Center Panel Absortive Design Intake/Exhaust Silencers

Designed for a high degree of high frequency noise attenuation. FPS model is for intake service and the FPSE for exhaust service.

Typical application: Internal combustion engine intakes and exhaust, compressor intakes or fan intakes and discharges.

Fields Marked with * are required

FP-FPE	Straight through, absorptive silencer design with no center panel for low pressure drop service. Expected attenuation is 15 to 20 dBA.
FPC-FPCE	Similar to the FPE but with an internal center panel which displaces part of the nominal flow area. Pressure drop is higher but the FPC is more compact in diameter, length and weight. Available in sizes 14″ and up, the FPC is excellent for engine and compressor intakes and fan intakes and discharges. Expected attenuation is 20 to 25 dBA.
FPS-FPSE	Designed with a center panel the FPS-FPSE body diameter is enlarged to enable an annular flow passage equal to the full nominal flow area. Pressure drop is intermediate between the FP and FPC models. Expected attenuation is 15 to 30 dBA.
