Considerations for Selecting the Type of Air Compressor Pump Oil

There are some things to take into account when selecting an air compressor pump oil type, including:


How efficiently an oil can lubricate a pump depends on oil viscosity.

The thickness and flow ability of the oil is determined by its viscosity. The viscosity of the oil has to be compatible with the range of temperatures that the compressor operates, and consideration should also be given to the oil’s viscosity index (VI) rating, as higher VI ratings signify greater performance throughout a wider range of temperatures.


Certain oils may include additives like corrosion inhibitors, anti-wear agents, and detergents. These additives can help the oil operate better while safeguarding the compressor pump from harm. The individual needs of the pump should be taken into consideration when choosing oil additives.


When choosing an oil type for an air pump, compatibility is crucial.

Ensuring the oil is suitable with the compressor’s seals and other parts is crucial.

The pump can sustain damage and lose the manufacturer’s warranty if the incorrect type of oil is used.

Oil’s life

The oil’s lifespan is a vital factor to take into account because it has an impact on the compressor’s maintenance needs and overall operating costs. Mineral oils often last less time and need to be changed less frequently than synthetic lubricants.

Hence, in the long run, synthetic oils might be a more economical option.


Environmental elements including humidity, temperature, and air quality can have an impact on how well the oil performs. When choosing an oil that can survive the conditions under which the compressor runs, it is essential to take these aspects into account.

For instance, high temperatures can hasten the breakdown of oil, while high humidity levels can cause water to contaminate the oil.

The reason why rotary screw air compressors require oil

Oil is required by rotary screw air compressors to lubricate the compressor pump’s working parts and preserve the system’s effectiveness.

Rotary screw compressors need oil to make sure that the internal parts function properly, as opposed to oil-free compressors, which depend on specifically created coatings and materials to prevent friction.

These are some explanations for why screw compressors require air compressor oils:

Lubrication: To reduce friction and wear, the internal rotors, bearings, and gears of a rotary screw pump must be greased. Air compressor oils create a thin coating between the moving parts, decreasing wear and friction and extending the compressor pump’s lifespan.

Cooling: By absorbing heat produced during operation, the oil also aids in cooling the pump. This lessens the possibility of internal component damage and helps keep the compressor from overheating.

Sealing: The oil also aids in sealing the compressor pump’s interior parts, reducing air leaks and maintaining the system’s effectiveness. The oil aids in forming a barrier between the rotors and other internal parts, slowing the escape of compressed air and lowering the power needed to run the compressor.

Cleaning: The oil also aids in clearing out pollutants and debris that may be amassing in the pump. The impurities are carried by the oil to the oil filter, which eliminates them from the system and aids in preserving the compressor pump’s effectiveness.

How often do you have to change the oil compressor

The kind, manufacturer’s recommendations, and operating circumstances are only a few of the variables that affect how often the oil needs to be changed in compressors and internal combustion engines.

Compared to screw compressors, reciprocating compressors need more regular oil changes, and older engines and reciprocating air compressors frequently utilize non-detergent oils.

For optimum performance, it is crucial to keep the oil level at the proper level, change the oil frequently, and replace the oil filters.

It is essential to choose the proper oil-lubricated air compressors, and it is best to abide by the manufacturer’s recommendations regarding oil type and viscosity.
