China High-efficiency air compressor oil - professional lubrication protection, improve compressor performance Suppliers, Exporters

Longhai Compressor Oil is formulated from high-quality distillate base oils through advanced solvent refining, dewaxing, and hydrofinishing processes. Enhanced with a premium additive package containing antioxidants, anti-wear agents, and rust inhibitors, this specialized lubricant delivers exceptional oxidation stability, thermal resistance, and low carbon deposition characteristics. Specifically designed for reciprocating and oil-flooded rotary compressors, it significantly extends equipment service life while maintaining peak operational efficiency.  

Product Description

Key Features & Benefits

1. Superior Oxidation & Thermal Stability

  • Synergistic base oil/additive formulation resists thermal breakdown at temperatures up to 110°C (230°F)
  • Advanced antioxidant chemistry extends oil life 2-3 times longer than conventional compressor oils
  • Reduces varnish formation by 60% compared to mineral-based alternatives (ASTM D4310)

2. Ultra-Low Carbon Deposition

  • Clean-burning formula minimizes carbon buildup on valves, piston rings, and discharge ports
  • Maintains heat transfer efficiency by preventing insulating deposits in critical areas
  • Meets ISO 6743-3A (DAA) and DIN 51506-VDL requirements for deposit control

3. Exceptional Wear Protection

  • Micro-film antiwear technology reduces metal-to-metal contact by 45% (Falex test results)
  • Specially formulated for medium-load compressors (up to 15 bar operating pressure)
  • Extends maintenance intervals by protecting bearings, cylinders, and crankshafts

4. Comprehensive Rust & Corrosion Prevention

  • Neutralizes acidic condensation formed during compression cycles
  • Water separation index >95% prevents emulsion-related issues
  • Protects all ferrous and non-ferrous components including copper alloys
