For so long, high maintenance costs and health problems have made people lose faith in air compressors. The costs of replacing filters, for instance, or dealing with messy oils and impure air are just some of these problems. However, modern manufacturers have resulted to oil-free air compressors that are less expensive to maintain and more efficient as well. If you would like to know more about these machines and perhaps get to invest in the best oil free air compressor for your DIY projects, read our oil free air compressor reviews guide below.

However, it is probably important to understand how these oil-less machines operate before selecting any single of them. For instance; there are air compressors cooled by an air cooling system while others are cooled by a water cooling system. In addition, different oil free compressors have different pros and cons. But we shall discuss this later on in our guide.

Benefits of Oil Free Air Compressors

Generally, both oil lubricated and oil free air compressors are capable of providing efficient services. As such, most buyers don’t really give much thought about the type of air compressor they want to buy. However, these days many people have become aware of the dangers associated with oil lubricated air compressors. Manufacturers have in turn responded by engineering oil free air compressors which have the following benefits.

1. They are light and smaller – A typical oil free air compressor features a 10 gallon or less air tank. They have an overall small size and weighs less than 50 pounds. In turn, these machines are easy to carry. Some can just be lifted with the help of a handle, while many will still feature padded wheels for maneuverability.
2. Lower cost of maintenance – Most people buy oil free machines because they cost less to maintain. With the absence of collecting oil laden condensates for instance or absence of filters to replace, the owner spends much money in maintenance.
3. Energy Saving – Oil free air compressors have low discharge pressure, which in turn helps save on power consumption. In addition, these machines unload horsepower faster, further increasing energy conserved.
4. Have reduced oil change intervals – True, many oil free models do require an oil replacement every year. However, oil flooded machines demand regular oil changes, which implies more mess to deal with in the long run.
5. They provide clean and reliable air at all times – Oil free machines supply high quality air that in turn helps protect your tools and your own health as well.
6. Fewer maintenance costs – Many oil free air compressor feature high quality construction and components. They are easy to control and are engineered to enhance performance as much as possible.
7. Oil free air compressors are generally cheap.

What to Look for in the Best Oil Free Air Compressors

Oil free air compressors are cheap and do not rely on oil for regular operation. But what else do you need to know about these machines before you spend your money? Can you find an industrial oil free machine for instance? Are there two stage air compressors? Continue reading to learn more.

Usually, oil free air compressors operate almost similarly to an oil lubricated air compressor. The biggest difference is that the latter models have to be lubricated with oil from time to time. With that in mind, ensure you confirm you are about to pick an oil free machine before you pay for it. This is because some manufacturers indicate their compressors don’t need regular oil replacement without clarifying that they must be lubricated.

• Ease of Transportation

  Oil free air compressors are generally built for DIY projects, which is why they should be light and easy to transport. A good machine, for instance, should weigh less than 50 pounds and come with never flat wheels for better maneuverability. They may feature a pancake design or horizontal tank, but the bottom line is that they should be portable.

• Efficient

  Efficiency in any air compressor is measured by how much air flow they can handle, their motor’s power and ability to recover air quickly. For many oil free models, an air flow of between 1.5-5 CFM at 90Psi would be ideal. A motor with a 1 HP and the ability to achieve up to 150 PSI would also be a better choice as it would help you with whatever DIY project you may have in mind.

• Power Source

  If you are avoiding an oil lubricated compressor for health reasons; also avoid a gas powered machine. Instead, opt for an electric compressor which is technically more convenient at home and for the small jobs you may have. In any case, modern air compressors are designed to function with normal 120V home sockets. Note however that electric models may have short power cords, in which case you may need to invest in a good extension cord.

• Tank Size

  Air compressors tend to cost more or less depending on the size of their air tanks. A 10 gallon air compressor, for instance, may cost much more than a 2 gallon machine. With that in mind, assess your workload and invest in an appropriate air compressor.

Conclusion

Finally, while the best oil free air compressors will have big tank sizes and more powerful motors, they may not be worth buying when you only need a machine for DIY projects. Instead, it is wiser to evaluate the power tools you need to operate, re-visit our oil free air compressor reviews and pick the most suitable machine for your needs. That way you will probably get to save more money while you still settle for a machine perfect for your needs. After all, that’s the best way to do business.
