Choosing the right air compressor lubricant depends on the type and application. For example, if the compressor is used for heavy, continuous, or high temperatures, synthetic or semi-synthetic oils are recommended. For general, less demanding applications, mineral or semi-synthetic oils are more suitable. Furthermore, the oil viscosity grade is important, with higher grades suitable for machines with high outlet temperatures. Budgetary considerations and oil life are also important factors.
Factors for Lubricant Selection
• Type of Air Compressor and Application:
• Piston Compressor: Choose oil with high temperature resistance, such as grade 68 oil. For heavy, continuous use, use synthetic or semi-synthetic oil to extend service life.
• Rotary/Screw Compressor: Choose grade 32 or 46 oil. For 24-hour screw compressors, choose high-quality, heat-resistant synthetic oils (such as grade 32) to reduce sludge and extend service life.
• Operating Temperature:
If the compressor is required to operate in confined spaces or in areas subject to high heat, choose heat-resistant oils, such as synthetic or semi-synthetic oils. For optimal performance and reduced oil deterioration
• Oil Change Frequency:
• Synthetic oils have a longer lifespan than conventional oils, making them ideal for those who don’t want to change oil as often.
• Extended Life Synthetic Oils can last up to 16,000 hours.
• Budget:
Synthetic oils are more expensive than conventional oils, but may be more cost-effective in the long run due to their longer lifespan and reduced maintenance costs.
• Specialty Applications:
• Food Industry: NSF-certified H1-class oils are recommended for safety.
Reminders:
• Maintain the correct oil level:
The oil level should be at the level indicated by the red dot on the oil gauge. Overfilling will cause excessive carbon buildup, and underfilling will damage parts.
• Regular Oil Changes:
Oil should be changed at the specified intervals, not just by adding more.
• Choose oil from a trusted source:
Consult a professional for the most accurate and appropriate advice.
