9 Best Oil Free Air Compressors Reviews 2021 | Easy To Use

It’s not that oil-lubricated air compressors are not good, but it is quite evident that a lot of people prefer oil-free air compressors as their daily drivers, and this is not without any reason.

They come as maintenance-free machines, but they also provide several other advantages, such as making less noise.

So, how do you choose the best oil-free air compressor for yourself?

There are a lot of options available in the market, which often gets you confused.

Today we will be going through the top 10 picks along with their pros and cons. Make sure you go through all to make the best choice.

Buyer’s Guide

Before I list down the top picks, there are some points I want you to be aware of first.

There are the points which you strictly need to consider if you want to make the best choice.


The volume of the tank is one of the most important features of an air compressor. If you fail to choose a compressor with an appropriate tank, it will be a bummer.

Either you will have to carry a lot heavier compressor, which you don’t need, or you will be refilling the compressor again and again amidst your work.

So, make sure you first analyze your needs, find out what volume would be enough for the things you will be working on, and then choose the tank volume that suits your needs.


The pressure is another very important thing which should be paid attention to before buying the air compressor.

Again, you need to know the requirements of the projects you will be working on and choose a compressor that provides more pressure than your requirements.

However, if you have small home tasks such as inflating tires, balls, or even powering small tools, this would not be an issue as most air compressors provide pressure enough for such tasks.

However, if you need more pressure, always check the specs of the compressor first.


When we talk about oil-free air compressors, noise is always a very important feature.

Most people buy oil-free compressors to work at home, which requires the noise levels to be kept to a minimum.

So, always go for the model, which makes the least noise possible if you are going to be using the compressor within your home.


Finally, the quality of construction is also pretty important when you think in the long term. Many people fail to notice this at first, but this is what eventually matters the most.

You don’t go out and buy air compressors every year, and if you buy a good one, it will easily last you for about four to five years.

Top 9 Oil-Free Air Compressors Reviews

I went through all the top-rated oil-free air compressors available and the ones with the best performance.

After reviewing them personally and going through customer reviews and ratings, here are the top picks that I came up with.

1. CRAFTSMAN CMEC6150K Air Compressor

Sitting at the top spot of my list, this is one of the finest products that I laid my hands on.

CRAFTSMAN is a brand known for making high-quality tools, and this air compressor is no different.

Coming in pancake style, it has a 6-gallon tank, which is a very appropriate size for dealing with small home tasks and comes with an accessory kit as well, carrying everything you will need.

The maximum pressure it can deliver is 150PSI, which is more than enough, and it’s great for working in cold conditions as well.

  • 150PSI max pressure
  • 13-piece accessory kit
  • Easy start-up in cold weather
  • Easy to use


  • A bit heavy to move around often

2. PORTER-CABLE C2002 Pancake Air Compressor

This is a very similar product to the previous one we saw; however, the only difference is that this one carries the tag of PORTER-CABLE on it.

Both have quite similar specifications and come in a similar price range, this one takes the lead with quicker recovery time, even though it has the same 6-gallon tank.

The water drain valve is very convenient to use while the rubber feet make the compressor very stable and easy to use.

  • Affordable
  • Quick recovery time
  • 150PSI max pressure
  • Easy starting in cold weather


  • Not so portable

3. PORTER-CABLE CMB15 Air Compressor Kit

CMB15 is a very decent-looking electric-powered air compressor that is available at a very affordable price tag.

However, it comes with a tank volume of only about 1.5 gallons, which is not much for heavier tasks but still very usable for small home tasks.

The good thing about this size is that it makes the tool very portable and you can move it while working, which is great.

Moreover, the recovery time is short, so even if you run out of air while working, it won’t take long to fill it up again, and the 120V motor is great for easy start-ups in chilly weather as well.

3. BOSTITCH BTFP02012 Air Compressor

If you want a top-quality air compressor for your mild home usage, which will not wear out anytime soon and you are bothered by a lot of noise as well, this is the best compressor to go with.

Making maximum noise of only about 78 dB, it has a very quiet functioning motor, which is amongst the most durable ones as well.

The tank is 6-gallons, again a very convenient size for a variety of jobs, and the high flow regulator is there as well for better airflow.

4. California Air Tools 8010 Air Compressor

This is amongst the premium quality compressors when we talk about oil-free air compressors.

Coming with a full steel body, you will not have an easy time finding something with a better construction quality than this one.

Moreover, it functions very quietly, only around 60dB, which is seriously good and can easily be used inside your home.

The volume is 8 gallons, but the tool is still very portable; it features tires.

  • Very portable
  • Ultra-quiet operation
  • Steel tank; very durable
  • Great value for money


  • Not so compact

5. California Air Tools 20020 Air Compressor

Coming from the same manufacturer and the same high-quality steel tank, this is kind of an upgraded form of the previous compressor we saw.

Having a 20-gallon tank is truly a monster, and I would not recommend it for your home usage.

With this size, it is extremely hard to move it around and is suitable for people who like the compressor to stay in one place but need to be compact.

The noise is quite less, only around 70dB, while it carries a powerful 2HP motor to fulfill all your tasks easily.

  • Powerful motor
  • Quiet operation; 70dB
  • 20 gallons tank

Yet another top-of-the-shelf product by the same manufacturer, this product comes with either aluminum or steel built tanks, which both are very durable and efficient in the long run.

It has twin tanks, a volume of 9.2 gallons, and a powerful motor of 2HP.

So, if you need something heavy-duty but need it to be a bit portable as well, go for this one without any more thoughts.

  • Very quiet; 60dB
  • Powerful 2HP motor
  • Aluminum twin tank

Coming with a low amp 120V motor, it will have no difficulty starting up even in cold weather and has a powerful 1/2HP motor as well.

Moreover, I liked the build quality of this thing. The thermal overload protection is a great thing to have, while a handle is also provided for easy handling of the machine.

Frequently Asked Questions

Let’s see some of the most frequently asked questions by the beginners and try to answer them.

What does Oil-Free Air Compressor mean?

It refers to the compressors which don’t need oil lubrication regularly.

How do I maintain my oil-free air compressor?

Check the air filter regularly. Drain the tank when not in use and check the safety valve of the compressor. This is what all you have to do.

How do oil-free air compressors work?

They are electric-powered and use the oil within the gearbox of the compressor.

Upon compressing the air inside the tank, they make pressurized air pumped to the tool connected to them. This is pretty much how they work.

It depends upon the quality and brand you choose. They can last anywhere within a year to 5 years based on those features.

Can you lay down an oil-free air compressor?

Yes, as long as there is no water in the tank.

Which is better oil or oil-less compressor?

Both have their pros and cons. An oil-lubricated compressor is better for heavy-duty and long-term usage while the latter is better for minor usage and low noise levels as well as less cost.

What is a good psi for an air compressor?

There are different opinions on this; however, at least 90PSI is considered par for a good air compressor.


We have seen how oil-free compressors are great for coming in at a great price point and not needing any maintenance costs as well.

They are pretty much the perfect picks for most minor tasks you could do at your home garage.

However, choosing them is the hard part, and after going through the products listed in this article, I hope you will have an easier time while choosing the most suitable pick for you.
