Leakage, damage to instrumentation, instability and noise are often caused by high frequency ripple generated by a hydraulic pump; an attenuator, placed close to the pump will significantly reduce this ripple.
The Fawcett Christie Noise Attenuator is essentially a low pass filter or volume resonator which attenuates transmitted frequencies over a wide band.
Fawcett Christie Attenuators are manufactured from forged steel with an interconnected inner chamber. Additional sound absorption is achieved if the attenuator is fitted with a flexible hose on both or either side.
