Air filters are used to remove solid particles which are carried in the air.

When air is compressed or processed to decrease pressure by a vacuum pump or a blower, the air must be filtered.

If air is not adequately filtered, dust or other particles can contaminate the blower or vacuum pump. This has a negative impact on the wear, life span and performance of the blower or vacuum pump.

In a worst-case scenario, contaminants in the air can combine to form a “grinding paste” which compromises the moving parts of the blower or pump and cause it to fail prematurely.

Oil separators are used for oil-flooded pumps for two purposes. They not only remove solid particles from oil, but also separate the oil from air that has been processed by the pump. The air is discharged and the oil is subsequently recirculated.
