To ensure your machinery is operating at optimal performance you need to ensure that all fluid systems are clean and unworn. With several fluid systems contributing to the operation of machinery, you need to minimise foreign bodies and the effects they can have on your engine. Foreign bodies such as dust or grit can adhere to surfaces, where it can 

-block tubes restricting fluid flow

-cover surfaces reducing thermal conductivity for cooling

-embed between moving surfaces causing abrasion in the engine

As powerful as the moving parts of mining machinery are, a small amount of dust can damage them, yet the movement of ore creates a huge amount of dust. Therefore, air filters are used within this equipment to filter out the dust and pollutants to avoid impeding their performance. Air filters are used in crushing and grinding machinery, loaders and trucks to name a few. Considering the amount of dust that these filters see, they need replacing pretty regularly. The replacement has to be incorporated into maintenance schedules, which is costly. Installing new filters is expensive and timely, not to mention the strain that they put on the environment when going into landfill.
