What is the function of the filters?

A filter is a circuit whose transfer function, that is the ratio of its output to its input, depends upon frequency. There are three broad categories of filter which are widely used: Low-pass filters allow any input at a frequency below a characteristic frequency to pass to its output unattenuated or even amplified.

Function

The function of the air cleaner element is to remove dust contained in the intake air so as to supply clean air to the engine, and protect the moving parts in the engine from wear. This seal ensures that outside air is not sent directly into the engine.

What is the function of air cleaner What is its type?

Air cleaner that is fixed in an internal combustion engines stops coarse particles to produce in engine’s cylinders. This can cause mechanical disturbance and oil contamination. Air purifiers is fixed near the throttle of the engine and its function is to clean the place for clean air to let in.

What is the need of filter in pneumatic system?

Typical commercial pneumatic filters will remove particles as small as 5 micrometres from the air. The filters protect pneumatic devices from damage that would be caused by these contaminants. These contaminants include lubricant particles ejected by the compressor, dirt particles, small water droplets or aerosols.
