9 Best Oil Free Air Compressors: Our 2020 Reviews

When it comes to completing tasks around your home, garden, and garage, an air compressor is one of the most underrated tools that you can own. Whether you are filling a tire with air, cleaning up the sawdust after a DIY project or powering a spray gun to paint your home, an air compressor can help you every step of the way.

But choosing the best air compressor for your needs can be a tricky job, with different brands, types, and sizes offering a huge range of positives and negatives for every option around. And, one of the most confusing questions (if not the most confusing) is whether to buy an oil or an oil free version… which is why we thought we’d put some information together to help you out.

Buying an oil free compressor is a worthwhile investment, but you want to ensure you buy the right one!

Oil vs Oil Free Air Compressors

So, what are the main differences between oil vs oil free air compressors?

  • Oil air compressors require regular oiling, whereas oil free air compressors do not (they are pre-lubricated)
  • Oil free air compressors require less maintenance
  • Oil air compressors are generally heavier in weight
  • Oil free air compressors are usually cheaper
  • Oil air compressors are more durable
  • Oil air compressors are quieter

6 Key Considerations when Buying an Oil Free Air Compressor

When you are looking at buying an oil free air compressor, there are 6 key things to consider before completing your purchase:

  1. What are you using your air compressor for? If you are only using it for small jobs, you will only need a small system. If you are using it for large jobs, however (like painting your car or completing some renovations), you are going to need a larger capacity tank.
  2. What brand of air compressor you are considering? Always purchase an oil free air compressor from a reputable brand, ensuring it has a good warranty and range of replacement parts and accessories to allow for a long lifespan.
  3. How quiet are you hoping your oil free air compressor will be? Oil free air compressors are generally louder than their oiled counterparts, however, there are options on the market that are quieter than others. Air compressors generally range between 40 to 90 decibels (dBA), and you will regularly find options that run at around 75 dBA classed as ‘quiet’.
  4. What PSI, or pound-per-square-inch, do your tools need? To ensure you can run any tools effectively, you need to ensure that an air compressor will provide the correct air pressure for any tools to run properly.
  5. What horsepower do you need? Horsepower (HP) is the measurement of power an air compressor motor produces, and the higher this number is, the more work an air compressor can do to deliver a higher PSI.
  6. What CFM (cubic feet per minute) specifications do your air tools have? CFM is the measurement of the overall air volume an air compressor generates, and different tools have varying requirements.

It offers 3.00 CFM at 40 PSI and 2.2 CFM at 90 PSI, with a quick tank fill time of around 165 seconds. Just because it is quiet, however, does not mean it is without faults. The California Air Tools Steel Tank Air Compressor is a heavy machine that can be a little tricky to move around, especially considering the odd angle of the small handle. It can also overheat quite quickly, so the temperature needs to be regularly monitored, and if the drain ball valve is opened all the way, it can become very noisy. Don’t let these aspects put you off however, as the California Air Tools Steel Tank Air Compressor is a great machine and the best on the market when it comes to ultra-quiet operation.

Our 2020 Oil Free Compressor Buying Guide

So, after reading all of that information, you’ve decided to buy an oil free air compressor. Where to from here? Well, you’ll be happy to know you’ve already made one of the hardest decisions – oil vs oil free – so here is a 7 Step Buying Guide to purchasing the best oil free air compressor for your needs. These tips and tricks will make this job a little easier, so we recommend getting out a pen and paper for this one, you are going to need it!

Step 1: What is your budget? One of the first things to consider is your budget. How much are you willing to spend? How much would you like to spend? If you are new to buying air compressors and are unsure as to how much machines cost, do a little bit of research before you answer these questions so you are being realistic with your price expectations. And, remember, you generally get what you pay for, so paying for a more expensive air compressor now may stop you from buying a cheaper option and then having to replace it in a few years.

Step 2: What are you using your oil free air compressor for? After you have decided your budget, you need to decide what you are using your oil free air compressor for. Is it for small DIY projects around your home, or is it for large-scale projects for extended periods? Either way, write down all the types of jobs your air compressor will be used for and try to be as thorough as possible. This will be used, in combination with steps 3, 4 and 5, to decide the power and size requirements you will need for an air compressor.

Step 3: What tools are you hoping to power with your air compressor? Next, write a list of all the tools you wish to use your oil free air compressor with. Whether it be a nail gun, a paint sprayer, an air hammer or something different altogether, write all these tools down in as much detail as possible.

Step 4: What are the power requirements of your tools? Now you have a list of the power tools you are hoping to use with your new oil free air compressor, try and write down the power requirements of your tools (e.g. what CFM and PSI they require) and these will set the parameters for your new machine. For reference, a drill usually averages 3-6 CFM at 90 PSI and a framing nailer generally averages around 2.2 CFM at 90 PSI.

Step 5: Where are you using your oil free air compressor? Where are you going to use your air compressor? Will it be moved around a lot? These questions will affect the height, weight and depth measurements that are most suitable to you, as well as the components which allow the machine to be moved around (such as handles and wheels). And let’s not forget about a protection cage, which will be needed to protect the air compressor from the elements, and to protect you from burning yourself on the air compressor or getting caught in moving parts.

Step 6: What oil free air compressor brands are available? After you have completed steps 1-5 above, you have likely put some ideas down on paper as to the size, type, and power requirements for an air compressor to suit your needs. Now it’s time to see what brands are available, and which ones offer models in line with your demands. If in doubt, always go with well-known brands who have experience producing air compressors, as they usually contain better warranty options and have longer lifespans. Check out brands like Dewalt, Briggs & Stratton, Porter-Cable and Hitachi, and you should be able to get an understanding of the prices and styles of air compressors available.

Step 7: Where are you looking to purchase your oil free air compressor? Are you hoping to get in-store and look at models in person, or are you happy to research and purchase online? Some people prefer to see items before they buy them, whereas others are happy to purchase from places like Amazon without having viewed the item in person first. Although purchasing online is generally easier, it doesn’t always mean it’s the best option, so make sure you do your research before you buy. Amazon is a great place to start!


Can you lay down an oil free air compressor? This is a bit of a tricky one, as there isn’t a set ‘yes’ or ‘no’ answer. If you have a brand-new oil free air compressor, laying it down shouldn’t be an issue. If it has been in use for a while, however, laying it down may cause maintenance and other problems due to a leakage of water and dirt from the tank. If you have to place the machine on its side though, ensure the tank is empty (absolutely no water) and it is firmly secured.

Are oil free compressors good? It all depends on what you need your air compressor for! If you are after an air compressor for heavy-duty usage, then an oil free compressor will not suit your needs (and you’re likely going to say they aren’t good!). If you are after a compressor for occasional use around your home and small-scale DIY projects, then an oil free air compressor is perfect.

How do oil free compressors work? Oil free air compressors work in the same way as oil air compressors, but the big difference is the lubrication. Both types use a piston to draw in air, and that air is then sent to a storage tank in a compressed form. For an air compressor to work at peak efficiency, the chamber that the piston is located in must be suitably lubricated. For oil air compressors, oil is used regularly. When it comes to oil free air compressors, however, they are pre-lubricated before you purchase them (using mostly Teflon) which lasts for the life of the machine and the pump is therefore protected by a Teflon coating. Oil free air compressors, therefore, need less maintenance and do not require regular oiling, whereas oil air compressors need systematic oil checks and refills.


All in all, the best oil free air compressor will change depending on your needs and circumstances. If you are completing small DIY jobs occasionally in your backyard, you will only need a smaller unit with lesser power and capacity. On the other hand, however, if you are frequently using your machine for large-scale projects for extended periods across different areas, you are going to require something with larger capacity, more power and the ability to be easily moved. Either way, the variety of models on offer ensures that there is something to suit everyone, no matter your needs. And, although all models have both pros and cons, there is a huge range of benefits offered by oil free air compressors that cannot be ignored. Just ensure you complete thorough research before you make a purchase and look at all the options available before making a decision. Good luck!
