Gulf Fidelity LL 68
Long Life Air Compressor Lubricant
Gulf Fidelity LL series are long life ashless air compressor lubricants developed for use in rotary compressors of screw or vane design, reciprocating compressors and centrifugal compressors to provide long and reliable service in extreme temperatures and severe operating conditions. Gulf Fidelity LL is manufactured from specially selected base fluids and advanced additive technology to provide excellent thermo-oxidative stability, resistance to sludge & varnish formation and wear protection similar to synthetic products meeting SAE M1003-2 specification.
Features & Benefits
- Outstanding thermo-oxidative stability and excellent anti-wear protection leads to longer oil and equipment life
- Low sludge, varnish and carbon forming tendency help in reducing maintenance cost
- High viscosity index coupled with excellent low temperature fluidity makes these oils suitable for use in wide operating temperature range
- Zinc-free formulation ensures excellent filterability by minimizing oil filter blockage in wet condition
- Excellent low volatility characteristics give low oil consumption and reduced top-up rates
- Improved surface properties results in very good anti-foaming and air release properties and superior demulsibility
- Offers excellent protection against rust and corrosion
- Compatible with mineral lubricants and also with seals and paints normally used with mineral oils.
Applications
- Single or multiple stage rotary screw or vane, centrifugal compressors and reciprocating compressors of various OEMs including Hydrovane, Sullair, Atlas Copco, CompAir and others.
- The formulation has undergone a successful field trial in Sullair Model 12-50H Screw Compressor (50 HP, 1780 rpm, air discharge temperature 93C) for 8502 hrs and in Hydrovane HV04-HV07 air compressors (air discharge temperature 120C) for 2450 hrs.
- Compressors used in mobile and stationary applications.
