Designed and developed specifically to meet the increasing demands of higher-pressure portable air compressors is the HPL 1500 lubricant. According to the manufacturer, the lubricant is especially suited for high-pressure rotary screw portable compressors, which are used in rigorous applications such as down-the-hole percussive hammer; deep water well and geothermal drilling; pipeline testing; oil and gas well servicing; sandblasting; rock drilling; and pile driving. It has a 1,500-hour change interval. The extended-life change interval minimizes environmental impact and saves both time and money on maintenance, the company said. The lubricant is a multiviscosity, highly refined synthetic hydrocarbon fluid, formulated to allow easier cold weather starting and faster warm-up, while providing lubrication in extreme hot or cold service. HPL 1500 is designed to operate in temperatures from -20° to 125°F. The 1500 provides wear protection and resistance to fluid oxidation and thermal degradation.
