COMPRESSOR OIL Series
 

Description

PSO COMPRESSOR OIL series are developed with high performing Ashless Additive Component Technology and hydro-finished super refined premium quality base oils to provide trouble free performance in reciprocating CNG and Air Compressors operating at maximum discharge temperature up to 220°C. PSO COMPRESSOR OIL provides high temperature stability and excellent lubricity to the reciprocating system of the compressor. Good film strength of PSO Compressor Oil protects the equipment component from rust and wear, particularly during intermittent operational conditions thus keeps the compressors in the best operating condition for the longer period.
 

Applications

  • PSO COMPESSOR OIL meets the requirement of major compressor manufacturers.
  • Applicable to single and multi-stage reciprocating compressors having maximum air discharge temperature 220°C.
  • Suitable to the compressor where OEM specifies ashless anti-wear R&O type lubricant.
     

Benefits

  • The combination of advance additive system and super refined base oils reduce carbon deposition at cylinder head.
  • High oxidation stability resists oil degradation, thickening of oil and sludge formation valve.
  • Low carbon deposit tendency at the critical area like discharge.
  • Excellent anti-wear and anti-corrosion properties protect compressor's components and enhance performance and equipment down time.
