What are oil-lubricated compressors?

Oil-lubricated air compressors are the air compressors that have an attached oil dipper to compressors’ bottom. The oil dipper splashes oil randomly from the crankcase reservoir to the internal parts and in the bearings of the compressors.

That helps to keep them lubricated. This is one of the most common forms of air compressor lubrication and mostly used in the reciprocating type of air compressor. The benefits that these types of air compressors offer are unmatchable. Here are a few of them.

With smaller size compressors the horsepower and the CFM both are less, and the portability of these compressors get them extra marks. True. But the user has to spend a lot of times again to fill this kind of tanks.

Is oil-free better than lubricated air compressor?

The oil-free and the Oil Lubricated Portable Air compressors have got perks and cons of their own. It mainly depends on your requirement. Well, the oil-free compressors are cheap, lightweight and produce a similar amount of airflow and pressure as that of the lubricated air compressors. But they are too much loud.

When placed in a room, they produce so much noise that at times it becomes difficult to sit there. That is among one of its main disadvantages. And it turns most of its consumers to switch to the Oil Lubricated Portable Air compressors. Especially, those with kids or elderly people at home.

Surely it is not going to damage the earbuds but it disturbs the mind.

Another catch is its durability. The oil-free compressors cannot serve long compared to the lubricated air compressors. That is because of its friction model that wears and tears the parts inside. The compressor goes out a few months after the purchase.

In a way, though it is cheaper, the durability factor forces the consumer to shop again. In every way, it apparently appears to be expensive to Oil-Lubricated Air Portablecompressors.

What is the best oil for the air compressor?

The Oil Lubricated Portable Air compressors require thick lubrication weightage in the summers or hot climate. On the other hand, the thin film is better for the cold weather. In this regards two different oils would be required to make proper use of the compressor.

Before you change the oil of your compressor it is better to study the manual. It has the complete information that what grading would be best for that compressor. Further, one of the best consumer recommendations includes Royal Purple Synfilm Recip 100 High-Performance Synthetic Air Compressor Lubricant.

This is a 30 weight lubricant, which equals ISO 100. Such oils are beneficial for all the climates. But they are best in the hotter ones.

If you are living somewhere in the cold climate or often have low temperature, then you would need a 20 weight oil. The Powermate Px P018-0084SP is one such example that is good for the low temperature or cold areas. This oil is detergent-free and it is synthetic. Certainly, this means that no carbon deposits as well as frictionless operation. Just like the Royal Purple this oil is also an all-weather lubricant. However, make sure to go through the manual before making any purchase.

What viscosity is air compressor oil?

The air compressor oils have varied viscosity. Commonly it is perceived that the viscosity of the oil is graded to run the Oil Lubricated Portable Air compressor in specific climates. But actually, the viscosity grading is to suit the mechanism inside the compressor.

The viscosity of the oil is very important when choosing the right oil for the compressor. Generally, the 20W or the 30W oils are available in the market. The 20W or 20 weight oils are thin and flow smoothly through the parts. Based on their watery attribute they are recommended for cold climates.

As thick viscosity can cause the machine to not operate properly. And even you may face difficult starting it up.

The 30W or 30 weight oils are best suited for the Oil Lubricated Portable Air compressors operating in the hot climate. They tend to reduce more friction compared to the thin oils. This reduces the heat generation in the machine as well as omits any wear and tear.

Consequently, the compressor performs smooth. Besides W or weight, the viscosity is also noted as SAE.

That is an equivalent measurement of oil viscosity. In addition to that, some oils are also labeled in ISO. The ISO scale is widely used to measure the viscosity of the lubricant.

Can I use regular motor oil in compressor?

Compressor oils need to be free from the detergents. But motor oils or the engine oils have the detergents included in them. The detergents affect the performance of the compressor. Alongside it also effects its durability. Certainly, the performance goes down as well as the durability is shrinking.

As a result, your compressor may not last longer than expected. Ahead of that, the detergents deposit carbon on the components increase the friction. The increased friction causes wear and tear. Although some of your friends may recommend using the motor or engine oil in the Oil Lubricated Portable Air compressor.

But that is not a good practice. They may even state that they have got no issues with it. It is because the issues start appearing with time.

Using a synthetic compressor oil means to increase the life of your compressor. The synthetic ability in the oil removes any friction in the components. Along with that, it keeps the parts running smoothly.

This enhances the performance of the Oil Lubricated Portable Air compressor. And it also increases its durability. Ahead of that, using the synthetic compressor oil may also increase its durability. This may reduce the maintenance cost over time.

What can I substitute for compressor oil?

Using the compressor oil in the Oil Lubricated Portable Air compressors is the recommended practice. But if in case, you wish to replace it, then some options may come handy. Although the compressor oils have everything needed for a compressor.

And even they cover every part within the machine. However, due to reasons like, unavailability of the right oil you may use the substitutes. Well, the hydraulic oils serve as one of the fundamental substitute. Especially they are beneficial for the low-temperature areas. There they could serve as the much-needed lubricant for the machine.

Besides, the transmission fluids are also another good substitute for the compressor oils. They have the ability to work as hydraulic oil. Ahead of that, they do not let the carbon deposit on the parts. Further, they even work as the coolant.

Additionally, they are also anti-oxidant, means the parts will remain rust-free. The synthetic oils could also do the job. But they are limited for a specific use. Well, the climate does not matter them at all. Instead, they can work in every situation.

These are best recommended when there are carbon traces in the machinery.

How do I change the oil in my air compressor?

Changing oil in the Oil Lubricated Portable Air compressor is like a walk in the park. First, make sure to read the manual for the oil changing methods. Generally, the Oil Lubricated Portable Air compressors have a similar method of changing the oil.

But usually, that differs is the pin location. Well, it is different than changing the oil in the car. And it would be better to be prepared else things could go wrong. When changing the oil, first locate the drain plug. The drain plug flows the oil out of the compressor.

Check for any obstacle that may cause trouble while draining the oil. You will need a pan or a bottle in which you could drain the oil. Plastic pans and bottles would be better to use as the drain catchers. Now put the pan or bottle under the drain plug and let the lubricant flow out of the compressor.

Most of the compressors may not require lifting to drain the oil stuck inside. But some may do. Ensure the complete drainage. After the oil has drained completely, plug the drain hose closed. When pouring the oil into the compressor do use a funnel. This makes it easier to add the oil in.

Why oil is used in the compressor?

The compressors need oil to run at full efficiency. Not all compressors need oil. Some compressors work without any lubricant. And compressors like the Oil Lubricated Portable Air compressors require oil. Comparatively, the oil compressors are more efficient and durable than the oil-less compressors. It is required to put the right oil only to make the compressor running for long and perform smoothly.

Well, compressors without oil are definitely cheap. Even they do not have any additional expense of lubricants. But they are less durable and live for very short time. This is because the machine inside the compressor is similar to the oiled compressors.

And when it does not get any lubrication, the parts start wearing out. Although the oil-less compressors come lubricated. But soon as that lubrication dries out, it starts deteriorating. And such compressors cannot be oiled because there is no inlet valve for the oil.

This is why the bigger compressors with great pressure and airflow use oil. It keeps the inside parts save and free from any friction. As a result, the maintenance cost is reduced and the lifespan is increased. We recommend reading the manual to know which oil is best for your compressor.

Can I use hydraulic oil in my compressor?

The hydraulic oils are different than the compressor oils. But they have some features that make them usable in the Oil Lubricated Portable Air compressors. First is that the hydraulic oils have lower viscosity. Means they are best suited for the cold climates.

If you are living somewhere with a cold climate, the hydraulic oils could be used instead of compressor oils. The oil flows smoothly within the parts compared to the compressor oil. As it is thinner, it lubricates the parts inside faster. And as a result, the compressor remains normal.

Well, the hydraulic oils are best for the crank-case or the pump compressors. Further, in the cold climates, it is better to use a 10 weight hydraulic oil.

Ahead of that, the hydraulic oils do not get oxidized. This lubrication quality keeps the material away from rust. Similarly, when put in the compressor, the inside parts will remain rust-free. Additionally, the compressors include sealants inside.

These are added to ensure the oil storage within the machinery instead of allowing it to the airlines. And the hydraulic oils are made to work with the sealants are similar material. Hence, it will cause no trouble to the compressor.

How much compressor oil do I need?

Every compressor has a different requirement for the oil. The instruction for the oil measurement could be read from the manual. Some of the Oil Lubricated Portable Air compressors require half a liter oil. But some may suffice with a couple of ounces.

The oil measurement depends on the size of the compressor. Every time the same amount of oil is to be poured inside. Any variation in the measurement could cause trouble. Trouble may include heat generation to the component’s failure.

The worse is that the compressor will stop functioning. So better read the manual to see how much oil you should pour in the compressor.

Besides, the frequency of the oil change depends on the usage. First, the type of the Oil Lubricated Portable Air compressor matters. If that is a reciprocating compressor, it may require oil change every three months.

This is also defined as after every 800 hours of operation the oil needs to be changed. But if that is a rotatory Oil Lubricated Portable Air compressor, it requires oil change after every 7000 hours of operation.

However, if you do not use the compressor frequently, make sure to change the oil once after every 6 months. As the oil stored in the compressor could cause damage.

Can I add too much oil to AC compressor?

Adding too much oil to the AC compressor is never recommended. Only fill it to the top when needed. Needed is judged by the dipstick. If the dipstick goes low on oil, the compressor will require to be filled to the top. Besides, this could also be judged by the behavior of the compressor.

If it is getting hot frequently or is creating too much noise, it means it needs oil. The recommended way is to change the oil when needed rather than adding to it.

But if the oil was changed recently before the behavior changed, the topping up would suffice.

Well, if too much oil is added to the compressor, it may flow to the airlines. When the compressor is unable to adjust the oil in the machinery, it starts flowing it out. Since there is no other way for drain then the drain plug. The compressor starts flowing it into the airlines.

And it comes out with the air. Although, most of the compressors have a separator that does not allow oil into the airlines. But in situations like overfilling the compressor, the separator may stop working. In that very situation, remove the excessive oil.

Conclusion

Considering the facts of the article, choosing the right compressor or saying that this one is better than the other one is tough.

  • The right compressor will be the one that best fit your requirements.
  • Always consider things like how much supportive crew you have.
  • There are also things like electricity and other things that you should keep in mind. That if you will get an uncut power supply in your workplace or you have to work with the oil-lubricated or the gas engine compressor.
  • Also, have a look at your budget before opting for any kind of portable air compressors.

However, no matter what air compressor you choose, maintaining them is a very important aspect to maintain their longevity. It is essential to maintain the inner components of the air compressor properly. The developers schedule this maintenance task, and you will get it most likely in the user manual.

Whether oil-lubricated or not, if maintained properly and used in the right applications, they will give a long-time service to the users.
