Advantages
♦ Outstanding oxidation stability and low tendency of carbon deposit, with long service life
♦ Small evaporation loss and low oil consumption
♦ Excellent viscosity-temperature and low temperature performance, ensuring easy startup in low temperature condition and good lubrication of compressor in high temperature condition
♦ Good oil-water separation ability and anti-foaming performance, rapidly separating water from oil condensed in air
♦ Good anti-rust and anti-corrosion performance, preventing parts of compressor from corrosion
♦ Good anti-corrosion performance, preventing part surface of compressor from abnormal wear
Applications
♦ Suitable for lubrication and sealing of low/moderate duty rotary air compressor in conditions of discharge temperature not larger than 130ºC and discharge pressure 1500kPa
♦ Lubrication of various reciprocating and centrifugal compressors
