HEAVY DUTY COMPRESSOR LUBE
L-DAC 46, 68, 100, 150
Introduction
PetroChina Lubricant Company’s L-DAC Compressor Oil series has supreme performance for the lubrication of heavy duty reciprocating air compressors used in industrial and marine applications. They are engineered to meet or exceed the stringent requirements of the major compressor manufacturers. They are formulated with superior synthetic base stocks and a high technology additive system that assures exceptional equipment protection and reliability for compressors operating under conditions where mineral oil-based products are not meeting expectations.
Applications
The L-DAC air compressor oil series is recommended for single and multistage air compressors used in marine, industrial and mobile applications air compressors. They are particularly effective in heavy service application.
Features
? Ensure wide temperature range capability and extended service life
? Outstanding oxidation and thermal stability to reduce coking deposits
? Low ash and carbon formation to improve valve performance and reduce deposits in discharge lines.
? High load-carrying ability to reduce wear of bearings and gears
? Excellent water separation decreases the sludge formation in crankcases and less potential for emulsion formation
? Effective rust and corrosion protection to improve protection of internal compressor components
? Good compatibility with all metals and sealing materials used in the compressor.
