This type of air compressor is most favorable, no doubt. But is it really for you?

Let’s have a look at the pros and cons to find out the answer-

    • Made to use for commercial purposes.
    • It can serve you for long hours.
    • Less noise, so, not bother others.
    • Reliable performance.
    • No heat issue found while using it regularly.

What We Didn't Like
  • Require regular maintenance.

  • Lots of parts are used

An oil air compressor is a heavy-duty compressor, which is mainly used for industrial and commercial purposes. Let’s have a look at their features and benefits-

Strong Built Quality
An oil-based air compressor is usually made from cast-iron and has a new metal shield to protect its body. So, if something hit the compressor, it will not break easily.

So, these are reliable and last longer. If you are going to use an air compressor for a long time, then an oil-air compressor is the best choice.

Less noise
Oil air compressor creates less noise. If you live in a populated area, then less noise is preferable. Because you will not get any complaints regarding noise.

Powerful
Bigger models need more power. An oil air compressor is more significant than an oilless compressor. So, it takes more power.

It takes more power to complete a big task. This is a powerful tool that is used for commercial and industrial jobs. Those jobs are heavy indeed. So, you have to have a powerful air compressor to complete this job.

In that case, an oil compressor is the only alternative to an oil compressor.

Lasts Longer
Oil air compressor lasts longer. Thanks to its heavy-duty metal body.

Though the metal body makes it heavier, it is well protected. And it is not a problem for industrial use.

You can do all compressed air work by an oil-air compressor. There is no limitation like an oilless air compressor.

So, you are getting all the jobs done and longer lifespan from an oil-air compressor.

Performance
It can withstand any severe condition and serve you. You need regular maintenance and changing the oil. You will not face any hassle to use it.

You can use an oil-air compressor the whole day without getting any heating issue on break.

Weighty product
This is a summary of the oil-air compressor. Uses, lifespan, portability, and durability are the primary concern from my point of view. What do you think?

Yes, you should think about that if it can serve your purpose or not. And then those factors. So, move to the next section to know about oilless air compressor and you will able to make your decision.

What do you think about the term “oilless”? The term oilless is a bit confusing here. It doesn’t mean that it can run without oil. Yes, it still uses oil. But the oils are set and sealed by the manufacturer. That means no oil can evaporate or escapes by other means.

You don’t have to add oil for its lifetime. That’s it. Isn’t it simple?

Let’s have a look at the features and benefits of an oilless air compressor-

No maintenance
Compared to an oil-air compressor, it requires no maintenance. Its oilless function minimal the maintenance need.

So, you are getting less hassle to maintain.

Cost-effective
An oil-free air compressor is made for home uses and DIY-ers. And fewer parts are used to make it. There is no extra metal protection. That makes it affordable in price tag.

It is a great advantage for homeowners and DIY-ers as they are not going to heavy use with an air compressor.

Portable
If you are working on small projects in various places, you should have the portability option.

The oilless air compressor is lightweight. So, it is easy to transport from one place to another.

High Quality of air
This is an oil-free model. There is some sensitive area where the air compressor is used. Such as food processing area. There you can’t use an oil-air compressor. Because it can release oil with compressed air. Though it is very negligible but not acceptable in a food processing area.

So, oilless air can help you in this regard. Because it does use oil, but the oil is in sealed condition. And its air is free from any harmful objects.

This is a summary of an oilless air compressor. You may now understand the term oilless and its uses. You can get this if it matches your requirements.

Are you still confused? Well, read the below section for head to head comparison. I think it will make stuff clear to you.

Comparison of size

An oil air compressor is more significant compared to the oilless air compressor. And that is why it is more powerful. But not portable.

On the other hand, oilless one is small and requires less space. You can quickly move it to your project area if you want.

Winner: It is depending on your need.  Are you a heavy user and going to do jobs only in one place? If yes, then go for the oil-based otherwise oilless is best for you.

Comparison of cost

We know that oil-based is more significant and influential. That’s why it is pricier. The minimum price of an oil-air compressor is $600.

On the other hand, an oilless air compressor can be found at only $200. Surely it is a low price regarding its versatile works.

Winner: If you compare the price, then oilless is the winner for sure. And if you compare price with type work, then oil-based is the winner.

Comparison of type of job

What kind of air tool are you going to use?
That is the prime concern. An oilless air compressor can run two nail guns simultaneously. And as I told you previously, it is ideal for home application.

And the oil-based air compressor is for industrial, such as for construction jobs. Are you a professional in such a job? Then it is for you.

Winner: It also depends on your job type. So, choose according to your job type.

Comparison of build-quality

The oilless compressor can break down quickly, and it does by the single metal hit. As it is built with fewer parts, it happens for that reason.

Comparatively, oil-based is made from cast-iron with other metal to protect. Thus, it is durable and excellent in build-quality.

Winner: No doubt, an oil-air compressor is a winner.

Comparison of uses of power

Oil-based is more considerable and works more big jobs than oilless. So, it will require more power comparatively oilless. Though air compressor is a power-hungry machine. It is just a comparative discussion.

Winner: Less power is the winner. So, the oilless compressor is the winner.

Frequently Asked Questions (FAQs)

Question #1: How do oil-less air compressors work?
Answer: Oilless air compressor brings air from outside via unloaded valve, and the air is filtered through an inlet air filter. Then the air compressed and stored in the tank.

Question #2: Do compressors need oil?
