Oil vs Oil Free Air Compressors

Oil-Lubricated Air Compressors

Air compressors that are lubricated with oil are the most conventional form of air compressor. Lubricating the engine with oil, which helps the compressor last longer, is a need for these machines. Additionally, the oil’s ability to dissipate heat contributes to the engine’s ability to stay cool.

When compared to oil-free compressors, oil-lubricated compressors often have a longer lifespan and require less maintenance than their oil-free counterparts. This is one of the many advantages of oil-lubricated compressors.

Oil-Free Air Compressors

Lubrication with oil is not necessary for the operation of oil-free air compressors. Instead, they rely on a variety of techniques to maintain the engine’s temperature and keep it oiled. Compared to oil-lubricated types, these compressors are often smaller, lighter, and more portable; nevertheless, they require more maintenance. On the other hand, oil-free compressors may not have the same level of durability as their oil-lubricated counterparts, thus they may not last as long.

Advantages of Oil-Lubricated Air Compressors

1. They’re More Durable 

The fact that oil-lubricated air compressors are constructed to survive for a long time is among the most significant advantages they provide. It is less probable for the compressor to incur wear and tear due to the fact that the oil serves to lubricate and preserve the interior components of the compressor. Because of this, oil-lubricated air compressors tend to have a lifespan that is far longer than oil-free versions.

2. They’re More Efficient

The ability of the oil to maintain a cool temperature throughout the inside of the compressor is one of its principal roles. This helps to increase the overall efficiency of the compressor because it reduces the amount of effort that is required to keep the temperature from fluctuating too much.

3. They’re More Powerful

Oil-lubricated air compressors are typically more powerful than oil-free ones, which is yet another advantage of these types of compressors. This is due to the fact that the oil helps to maintain the internals of the compressor operating smoothly, which enables the compressor to work harder and create more air.

4. They’re Quieter

In general, oil-lubricated air compressors are quieter than oil-free types. This is due to the fact that oil-lubrication makes the compressors more efficient. This is a significant benefit to consider if you are seeking for a compressor that will not interfere with your activities at work or at home.

Disadvantages of Oil-Lubricated Air Compressors

1. They Require Regular Maintenance 

One of the most significant drawbacks associated with oil-lubricated air compressors is the requirement that they undergo routine maintenance. This involves doing routine oil changes and keeping a close check on the level of oil in the vehicle to make sure it doesn’t drop too low. If an oil-lubricated air compressor is not properly maintained, its lifespan might be significantly shortened, and its overall efficiency will suffer as a result.

2. They’re Not as Portable  

Oil-lubricated air compressors have a number of drawbacks, one of which is that they are not as portable as oil-free ones. This is owing to the oil reservoir, which normally results in a greater amount of weight. In addition, transporting oil-lubricated air compressors can be a messy endeavour since the oil may spill out while the compressor is in motion.

3. They’re Not as Clean 

Because they don’t require oil to function, oil-free air compressors are far more environmentally friendly than their oil-lubricated counterparts. This is one of the most significant benefits of oil-free air compressors. If you plan on utilising your compressor at home or in an office setting, this is an essential factor to take into mind.

Advantages of Oil-free Air Compressors

1. No oil needed

This is by far the most significant benefit offered by oil-free air compressors. You won’t ever have to bother about changing the oil or topping it off because there is no requirement for oil in this system. Furthermore, oil-free air compressors are significantly simpler to carry since they do not have the potential to leak oil while being transported.

2. More portable 

Oil-free air compressors offer an additional benefit in the form of increased portability in comparison to oil-lubricated ones. This is due to the fact that there is no oil reservoir in them, hence their weight is often lower. Oil-free air compressors take up far less space, making them much simpler to store than their oiled counterparts.

3. Cleaner 

Oil-free air compressors are far more hygienic than their oil-lubricated counterparts, which is one of the most significant benefits associated with oil-free devices. This is due to the fact that there is no requirement for oil, which means there is no oil that may seep out and generate a mess. In addition, because there is no oil for dust and filth to adhere to, oil-free air compressors have a lower propensity to gather the two.

Disadvantages of Oil-Free Air Compressors

1. They’re Not as Efficient 

The fact that oil-free air compressors are not as energy-efficient as oil-lubricated ones is one of the most major drawbacks associated with these machines. This indicates that they will take more energy to operate, which will ultimately result in greater expenditures to maintain.

2. They Create More Heat 

The fact that oil-free air compressors generate more heat than their oil-lubricated counterparts is one of the most significant drawbacks associated with these machines. This is due to the fact that oil assists in the dissipation of heat; in its absence, the compressor would run at a higher temperature.

3. They’re Noisier 

Another disadvantage of oil-free air compressors is that, in general, these machines produce more noise than their oil-lubricated counterparts. This is due to the fact that the absence of oil might cause the compressor to vibrate more, which results in an increase in the amount of noise produced.

Which Type of Air Compressor is Right?

After learning the benefits and drawbacks associated with oil-based and oil-free air compressors, you are in a better position to choose the model that meets your needs. If you are looking for a compressor that is not only strong but also long-lasting, you should consider purchasing one that is oil-lubricated. On the other hand, if you want an alternative that is both less expensive and simpler to maintain, an oil-free compressor can be the best choice for you.


How can I make my small air compressor quieter?

There are a few different approaches you may take to lessen the noise produced by your portable air compressor. To begin, put a soundproof inclosure around the equipment. This will assist in reducing the amount of noise that is produced by the compressor. In addition to this, you may put your compressor on a mat designed to absorb noise. This will contribute to the absorption of vibrations and the reduction of noise.

Are oil-free compressors quieter?

Compressors that do not use oil do not always have a lower noise level than compressors that do use oil. On the other hand, they could be more effective and demand a lower level of upkeep.

Is an oilless air compressor better?

Compressors that don’t require oil offer a number of benefits. They are more effective while also requiring less upkeep on your part. In addition to this, oil-less compressors are often more quieter than their oil-based counterparts.
