Gulf Fidelity 100
High performance air compressor oil
Gulf Fidelity series are high performance ashless air compressor oils specially designed to meet the stringent requirements of major compressor manufacturers. These oils are formulated with high quality base oils and carefully selected performance additives to provide excellent protection against oxidation degradation, rust & corrosion and foaming & entrained air. The low carbon forming tendency coupled with high FZG rating make these oils suitable for both reciprocating and rotary air compressors. These oils exceed the performance requirements of DIN 51506 VDL and ISO 6743-3:2003 DAA Normal Duty.
Features & Benefits
- Excellent thermo-oxidative stability controls the formation of sludge & varnish on valves & piston crowns and improves oil life resulting in improved equipment reliability, availability and efficiency.
- Low ash and carbon forming tendency ensures improved valve performance and reduced potential for fires and explosions in the discharge systems.
- Exceptional wear and rust protection results in reduced maintenance costs and longer equipment life.
- Superior demulsibility reduces oil carryover and corrosion, maintains lubrication efficiency, reduces sludge formation and improves life of coalescers.
Applications
- Reciprocating air compressors operating with a high discharge temperatures of up to 220ºC used in stationary and mobile applications.
- Rotary screw and vane compressors
- Axial and centrifugal compressors
- Also used in circulating oil systems, plain and rolling element bearings, lightly loaded Gear sets, etc
