Other Considerations

Viscosity Grades

Viscosity refers to the oils thickness or resistance to flow. Compressor oils are categorized by viscosity grades, typically represented by numbers such as ISO 32, ISO 46, or ISO 68.

Viscosity affects how well the oil performs in different temperature conditions. Lower-viscosity oils are better suited for cold environments, while higher-viscosity oils excel in hot conditions.

The right viscosity ensures proper lubrication, reducing friction and minimizing wear on compressor parts.

Compatibility

Choosing compressor oil that is compatible with your compressors materials is essential. Incompatibility can lead to corrosion, damage, and costly repairs. Always check the manufacturers recommendations to ensure the chosen oil is suitable for your compressors construction materials, including seals, gaskets, and metals.

Oil Additives

Compressor oils often contain additives to enhance their performance.

Anti-wear additives reduce friction and wear on compressor parts, extending their lifespan.

Oxidation inhibitors prevent the oil from breaking down due to exposure to air, prolonging its life and maintaining performance.

Environmental Impact

Environmental factors like biodegradability and eco-friendliness may influence your oil choice. Biodegradable compressor oils are available for applications where environmental impact is a concern. Always consider the ecological implications of your choice, especially in environmentally sensitive settings.

Alternatives

Alternatives to traditional air compressor oils include automatic transmission fluid (ATF), hydraulic oil, and motor oil. These alternatives offer different performance characteristics and can be chosen based on factors like temperature, environmental concerns, or industry-specific requirements.

The Benefits of Using the Best Air Compressor Oil

Industrial air compressors require regular repair and maintenance to keep them in tip-top shape. Its best to check essential parts such as the intake vents, belts, motor bearings, filters, and lubricants periodically. The air compressor oil needs to be changed every 100 to 200 hours or as specified by the manufacturer.

Using the best air compressor oil for your pneumatic device offers several crucial benefits:

• Improves Compressor Lifespan: Additives in compressor oils protect the machines components and extend the lubricants usable life. These elements also allow the oil to lubricate correctly according to various operating conditions.
• Anti-Foaming: Foam is produced when air bubbles rise to the oils surface, increasing the oxidation within the air compressor. The best-formulated oils reduce foaming to help reduce energy consumption and oxidative stress. This effect prolongs the life of your pneumatic device.
• Improved Viscosity: The best-formulated air compressor oils have better resistance to temperature changes, allowing them to maintain their lubricating properties.
• Demulsification: High-quality compressor oils can protect air compressors from water emulsion by separating water effectively.
• Improves Heat Absorption: Using the correct oil for your compressor helps keep the unit cooler. Well-suited lubricants can absorb the heat from compressed air to prevent overheating.
• Oxidation Resistance: With better oxidation resistance, additives in air compressor oils can better prevent acid formation and improve corrosion resistance. Further, they can protect your machine from rust and degradation, extending its service life and improving its performance.
• Improves Efficiency: Using the right compressor oil boosts its operating efficiency by reducing wear and friction between the machines moving parts. When efficiency is reduced, your sites productivity increases due to less downtime.
• Easy Maintenance: The best oil suited for your compressor can make machine maintenance easier. All the parts will be well lubricated, thus reducing damage from regular wear and tear. This means you dont have to replace parts that often, reducing maintenance costs.

Standard vs. Synthetic Air Compressor Oils

Which air compressor oil is better synthetic or standard oils? These are the two most common compressor oils recommended by pneumatic device manufacturers.

Standard Air Compressor Oils

This type of oil for air compressors has a mineral oil base, which makes it more budget-friendly. Its the type of oil recommended for homeowners and businesses that do not operate their compressors continuously. If you use your machine for light to medium operations, this is the type of oil best suited for your air compressor.

Synthetic Air Compressor Oils

Synthetic air compressor oils are formulated for commercial and industrial use. These oils are better suited for compressors that will be used continuously for many hours. If you use your compressor three or more times a week, its best to use synthetic oils since they can better provide cooling and lubrication for prolonged operations. At Fitz Equipment, we recommend using synthetic oil if youre using heavy-duty commercial air compressors, such as Gardner Denver machines.

Synthetic oils are better than the standard variants when protecting air compressors from overheating. These oils can provide a wide range of protection, an excellent fit for work sites in areas with extreme temperatures. Further, synthetic oils promote quiet operation, which can benefit many businesses.

Oil Viscosity

Many air compressor manufacturers recommend using 20 to 30-weight compressor oil for their machines. A 30-weight oil is thicker or more viscous, which makes it a better choice for air compressors used in worksites located in hotter areas. You can switch to a 30-weight oil during summer but use other less viscous oils during colder months.

Twenty-weight oils are less dense and are better suited for cold start conditions. If you use 30-weight oil in colder environments, your compressor may not start immediately. Its best to use less viscous oil with less weight during winter or in areas where the temperature is usually colder than in other locations.

When to Use Food-Grade Air Compressor Oil

Its mandatory to use oil-free compressed air in any food production process, especially if compressed air comes in contact with any ingredient. In these facilities, its best to use non-lubricant compressors, which produce class 0 purity compressed air. In cases where compressed air will not come in direct contact with any food products, its acceptable to use lubricated air compressors. However, these machines should use food-grade oil.

Air Compressor Oil Substitutes

Sometimes you may be forced to use substitutes for your compressors oil, especially when specialty oils are in short supply. Here are some of the alternatives that can be used temporarily.

• Motor Oil: Motor oil is readily available but may contain detergents that help clean internal combustion engines. If you use motor oil for your air compressor, use one with no engine detergents.
• Automatic Transmission Fluid (ATF): Some ATFs can work well as a substitute for air compressor oil. They can reduce friction and wear during more prolonged operations. Further, transmission fluids can help reduce the heat produced by an air compressor. However, be careful when using transmission fluid since some of these products may contain additives that can damage an air compressor.
• Hydraulic Oil: Hydraulic oil has similar qualities to many air compressor oils. This oil has a lower viscosity, making it a good option for operating compressors in colder climates. In addition, oil can improve corrosion resistance.

Our experts at Fitz Equipment recommend using air compressor oil substitutes only when you have to. Some alternative oils can damage your compressor.
