First and foremost, it’s necessary to understand what compressor oil is used for, in order to better understand and comprehend the importance of proper lubrication.
Compressor oil plays multiple roles:
There are several types of compressor oil, each with its own specific application and benefits. Let's take a closer look:
Mineral oil is derived from refined crude oil and is typically recommended for smaller compressors, units used intermittently, and home and DIY applications.
Benefits:
Synthetic oils are chemically engineered for superior performance, making them ideal for professional applications, industrial environments and compressors running for long hours.
Benefits:
Expert advice: If you operate a rotary screw compressor or run your units continuously, synthetic oil is usually the best choice.
Beyond the type of oil, the application, the type of compressor, and even the overall environment in which the oil will operate also play a role in the selection of lubricant. We explain everything:
Different compressors have different lubrication requirements. For example:
For instance, heavy daily use requires a more durable oil, while occasional light use may be fine with mineral oil.
The environment, meanwhile, affects the reaction of the oil and its "evolution" in the environment in question. Indeed:
In general, it’s always recommended to refer to the manufacturer's manual or handbook, because if you use an oil that is deemed “not recommended”, it may reduce the lifespan and efficiency of your machine and void the warranty.
Oil grade refers to viscosity and additive composition. This is another important factor to consider when choosing your compressor.
Correct viscosity ensures:
Maintenance is (as with all compressed air equipment) key to ensuring that your compressor lasts a long time and to quickly correct, or even anticipate, oil-related problems. For example:
Some additional maintenance tips:
The type of oil to be used depends on the compressor type, the usage, and the operating environment. What we recommend is that you always check your manual first.
Correct oil ensures proper lubrication, prevents overheating, and preserves efficiency.
No. There are Oil free compressors, and they are ideal where oil contamination must be avoided.
This is not recommended since generic oils don’t protect adequately, which results in shortening equipment lifespan and in causing higher oil carryover.
Risks include:
Our expert advice: Always use the recommended type and grade.
