Product Data Sheet
Product Sinopec L-DAB Air Compressor Oil
Summary Product description
Sinopec L-DAB Air Compressor Oil is a line of lubricants blended using highly
refined mineral base oils and a selected additive system. It is designed for use
in various stationary or mobile reciprocating air compressors in medium-duty
applications, and is available in four viscosity grades, ISO 68, 100, 150 and
220.
Applications
Sinopec L-DAB Air Compressor Oil is suitable for use in:
• All types of reciprocating air compressors where a DIN 51506 VDL oil is required, for once-through cylinder lubrication
and also to lubricate compressor crankcases.
• Single-stage and multi-stage reciprocating air compressors.
• Compressors that handle air, inert gases (such as nitrogen, argon, neon and helium), carbon dioxide, carbon monoxide
and blast furnace gas.
• Stationary and mobile units.
• Some rotary vane and screw compressors.
Caution: not recommended for breathing air compressors.
Features and benefits
• Excellent lubricating properties protect moving compressor parts against wear and extend component life.
• The highly refined mineral base oil has outstanding thermal and oxidation stability and low carbon-forming tendency
compared with conventional mineral oils, and this leads to good compressor cleanliness, reduced deposits and
improved compressor efficiency, even when air discharge temperatures are high (up to 220°C).
• Reduced deposits in discharge lines, reducing the risk of fires and explosions.
• Good anti-rust and anticorrosion properties protect cylinders and discharge valves from rusting and corroding,
enhancing equipment life and performance, and prolonging service intervals.
• Excellent water-separation characteristics ensure that condensed water vapour can easily be separated from the
lubricant and prevent the formation of emulsions (which could block the oil/air separator (coalescer) in some
compressors), therefore prolonging coalescer life, and reducing equipment downtime and maintenance costs.
• Improved oil quality leads to longer maintenance and overhaul intervals and extended oil drain intervals, compared
with poorer quality products.
