Description
Sinopec L-DAB Air Compressor Oil, SAE 20, ISO 68 is blended using highly refined mineral base oils and a select non-detergent additive. It is designed for use in various stationary or mobile reciprocating air compressors including pneumatic, reciprocating and rotary screw compressors in medium-duty applications.
Pack Size: 55 Gallon Drum (200L Volume), Grade: SAE 20, ISO 68
Features & Benefits
Sinopec L-DAB Air Compressor Oil, SAE 20, ISO 68 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.
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.
