Heart of any equipment is the Engine. Dust is the major killer of an Engine.
Dust  can enter an engine from different sources but the most common path of entry is through the air intake system. Airborne dirt particles ranging in size from 10 to 100 microns cause the maximum damage to the engine. One micron = 0.000039ths of an inch. Silicates are the most harmful particles which are of this size range. Silicates (sand) in the cylinders will crystallize to a diamond-like hardness when the engine operates.

It takes only takes an average of eight (8) ounces of dirt to ruin an engine. Problems caused by even small amount of dirt getting past the filtration systems can be catastrophic. Premature wear of bearings, rings, and cylinder surfaces are some of the results of dirt entering the system. This would result in excessive oil consumption as worn cylinder walls and rings would allow lubricant into the combustion chamber.
