Because of the different parts of filters it is easy to design the circuit for a wide range of bandwidth. But normally several identical sections are used to reduce the pulsations as effectively as possible. The compressed air leaving the compressor should be properly prepared before it goes into the circuit.
The circuit diagram and smoothened waveform of a full wave rectifier output is shown below.
A filter circuit is a device to remove the ac components of the rectified output but allows the dc components to reach the load. The circuit diagram of this filter is as shown in the below figure where the first half is for active high pass filter and the second half is for active low pass filter. A capacitor allows ac only and inductor allows dc only to pass. Therefore filter circuits consisting of inductors can only be used together with full wave rectifiers.
