AEON Synthetic Compressor Oils

AEON 9000 SP

AEON 9000 SP is Gardner Denver’s premium 100% synthetic rotary screw compressor oil. It’s designed for long drain intervals, high operating temperatures, and demanding industrial environments.

  • Extended oil life (up to 8,000 hours)
  • Excellent oxidation and varnish resistance
  • Ideal for stationary rotary screw compressors
  • Helps maintain airend efficiency over time

If your compressor runs hard, runs hot, or runs continuously, AEON 9000 SP is often the preferred choice.

AEON 4000 / AEON 5000

AEON 4000 and AEON 5000 are synthetic compressor oils commonly used in portable rotary screw compressors and lighter-duty applications.

  • Designed for portable and mobile compressors
  • Reliable performance in variable operating conditions
  • Shorter drain intervals than AEON 9000 SP
  • Up to 4,000 hrs
  • Often specified for construction, rental, and jobsite equipment

These oils are application-specific. They’re simply engineered for machines with different duty cycles and service expectations.

AEON 6000 FG

AEON 6000 FG is a food-grade synthetic compressor oil formulated for facilities where incidental food contact is a concern.

  • NSF H1 registered
  • Used in food, beverage, and pharmaceutical environments
  • High oxidation stability
  • Maintains clean operation in sensitive applications

If your facility requires food-grade compliance, AEON 6000 FG is typically the correct specification.

AEON PG

AEON PG is a polyalkylene glycol (PAG) based lubricant designed for specific compressor applications. PAG is often chosen for high-heat, high-load rotary screw compressors.

  • Excellent lubricity and cleanliness
  • Often specified by OEM requirements
  • Not compatible with most petroleum or PAO oils

Important: PAG oils should never be mixed with other oil types. Always confirm compatibility and changeover procedures before switching.

Petroleum-Based AEON Oils

AEON 2000

AEON 2000 is a petroleum-based compressor oil designed for older compressors or applications with shorter maintenance intervals.

  • Mineral oil formulation
  • Shorter oil life than synthetics
  • Common in legacy equipment

AEON 500

AEON 500 is also a petroleum-based oil, typically used in older or lower-temperature applications.

  • Conventional mineral oil
  • Frequent oil change requirements
  • Best suited for legacy systems

Petroleum oils still have a place, but many operators upgrade to synthetic oils to reduce maintenance and extend service intervals.

Choosing the Right Gardner Denver AEON Oil

The right AEON oil depends on:

  • Compressor type (stationary vs portable)
  • Operating temperature and duty cycle
  • Food-grade or compliance requirements
  • OEM specifications
  • Desired oil change interval

Matching the oil to the application (not just the brand name) is what protects your airend and keeps your compressor running efficiently.

Gardner Denver AEON Oil Replacements

We carry high-quality replacement compressor oils that meet or exceed Gardner Denver AEON specifications. These oils are formulated for performance, cleanliness, and long service life without unnecessary downtime.

Direct Replacement Lubricants for Gardner Denver AEON Oils

Many facilities actively search for terms like “AEON compressor oil replacement” or “AEON 9000 equivalent”. In most cases, they are not looking to change how their compressor operates. They are looking for an oil that delivers the same protection, cleanliness, and service life without being tied to OEM branding.

A true direct replacement lubricant for AEON oil is selected by matching performance characteristics, not just the name on the label. When properly matched, a replacement oil performs the same function inside the compressor.

A proper AEON replacement lubricant is evaluated against:

  • Base oil type (PAO synthetic, food-grade synthetic, PAG, or petroleum)
  • ISO viscosity grade
  • Oxidation and thermal stability
  • Varnish and deposit control
  • Expected drain interval

When these criteria are met, the compressor does not “know” whether the oil is OEM-labeled or a replacement. It simply sees consistent lubrication and protection.

AEON 9000 SP Equivalent Oils

AEON 9000 SP is the most commonly referenced AEON oil, and it is also the most frequently searched for replacement or equivalent options.

A direct replacement for AEON 9000 SP should be:

  • 100% synthetic (PAO-based)
  • ISO 46 viscosity (where specified)
  • Designed for continuous-duty rotary screw compressors
  • Rated for extended drain intervals
  • Highly resistant to oxidation and varnish formation

When these requirements are met, a replacement lubricant can provide the same level of protection and service life expected from AEON 9000 SP.

AEON Oil Compatibility & Changeover Considerations

Before switching from OEM AEON oil to a replacement lubricant, it’s important to understand compatibility.

  • PAO synthetics are generally compatible with other PAO synthetics
  • PAG oils (AEON PG) are not compatible with PAO or petroleum oils
  • Petroleum oils should not be mixed with synthetic oils without proper flushing

If your oil label references AEON but you are unsure which version applies to your compressor, identifying the correct oil type first helps ensure a smooth transition.
