Premium Performance Rock Drill Oil

Product Description

AROX™ EP Series rock drill oils are premium quality high performance products primarily intended for the lubrication of pneumatically operated rock drills in underground and surface mining operations. AROX EP Series rock drill oils are formulated from high quality base stocks and carefully selected additives that are designed to provide excellent chemical stability and outstanding protection against wear and corrosion. They are also designed to offer an optimum balance between adhesiveness and emulsibility. This feature allows the lubricant to absorb moisture carried in the wet mine air system, while maintaining a protective oil film on the drill components. The potent EP characteristics of AROX EP Series rock drill oils provide excellent protection for the drill components that are subjected to percussive contact, thereby helping to improve equipment life in heavily loaded mining equipment. AROX EP rock drill oils possess high viscosity indexes and low pour points to ensure good lubrication at high and low operating temperatures.

In underground drilling operations, even a perfectly adjusted automatic oiler will cause oil mist to be exhausted to the atmosphere. AROX EP rock drill oils have been fortified by the addition of a tackiness additive, which helps to minimize stray oily mist. The reduction of stray oily mist in the work place can help lead to a safer and healthier work environment.
