Extending Oil Change Intervals on Heavy Mining Equipment

Larger 10-micron absolute air breathers were also installed on the hydraulic tank. The filters used were high-quality depth filters that are very efficient with good dirt-holding capacity. At these hours, the filters went into bypass. The direct savings on hydraulic filter costs for the fleet of haul trucks were approximately $121,000 per year.
