Best oil lubricated portable air compressor (Reviews & Buyers’ Guide)

bestoil lubricated portable air compressor

Are you in dilemma on what means of power to use when driving your tools? Do you know that air is the most powerful source of energy yet it freely exists in the atmosphere? This is true but most people don’t know and that’s why they end up making poor workshop decisions. The invention of an air compressor is one of the shaping schemes that make science interesting. An air compressor is a tool that stores air under pressure which is in turn used to power air tools. In this article, I am going to take you through the best oil lubricated portable air compressor reviews and buying guide.

An oil-lubricated air compressor is advantageous since they generally run quietly compared to oil-free air compressors. Moreover, the oil reduces friction thus minimizing wear and tear on the contact parts. Portability is also important since you’ll have to move your unit from one place to another. Meanwhile, let’s start with the reviews of the best air compressor in the market.

Best Oil Lubricated Portable Air Compressor Buyer’s Guide

Any DIY enthusiast, hobbyist, contractor, or mechanic must arm themselves with an air compressor that can keep up. After going through our well-researched list above you are now welcomed to this section where we give more insights on what to look for in your air compressor. Without much ado, let’s delve into the factors to consider when shopping for the best oil lubricated portable air compressor:

Horsepower

Horsepower is a vital factor to dig into before buying an air compressor. Unfortunately, most manufacturers lie on the exact horsepower of an air compressor to increase their sales. The most reliable manufacturers are the Industrial Series that provide accurate horsepower ratings. The horsepower determines the amount of work an air compressor can run. For instance, a highly rated unit can run heavy-duty tasks. 

Air Pressure (PSI)

The air pressure is measured in pounds per square inch (PSI). A good air compressor should have higher shut-off pressure. That means it should provide a higher pressure than what your tools needs. Most air compressors build pressure in two stages such that when you subtract the pressure loss due to couplers and hoses restriction it is still enough to power your tool. 

Cubic Feet Per Minute (CFM)

Pneumatic tools demand a certain volume of air to run. This is measured in cubic feet per minute (CFM). It is the amount of air that an air compressor can deliver in a minute. You will observe that most CFM ratings are marked at 90 PSI which is the pressure most air tools require to run. A good air compressor must provide an airflow that is more than the demanded CFM from your tool. Therefore, before buying an air compressor you must first check the CFM requirements of your tool. 

Tank Capacity

Yes! Size does matter when it comes to air compressors. The tank size determines the amount of air that can be stored in the compressor. When working on continuous jobs like spraying you cannot break until you finish getting a uniform coat. Therefore, you’ll have to get a larger tank size to continue with the project without stopping to refill. Actually, this also saves time. However, if you can work intermittently then a small air compressor is fine. Small tanks are also advantageous because they are portable and fills up quickly. The size of the tank is measured in gallons. 

Duty Cycle

The duty cycle is an important aspect when shopping for your air compressor. This is the time taken by an air compressor to run continuously before stopping. For instance, an air compressor with a 50% duty cycle means it can run for 30 minutes and rest for another 30 minutes. If you run them past the duty cycle the unit will become too hot and this reduces the service life. The higher the duty cycle the better and those units with 100% duty cycle are the best since you can run them continuously as you wish. 

Life Expectancy

I know that you’ve worked hard to get the cash in your pocket and every time you spend you must act wisely. You’ll love value for your money, right? So, you must go for brands that last longer. To arrive at durable air compressors you must choose well-known brands that have been in the market for many years and are still doing better at air tools manufacturing. I’ll advise you to choose an air compressor with a longer life expectancy to enjoy most of its services. You will see that durable air compressors are a bit costly but the difference in prices is very little. So, spend a little more cash to get a product that will serve you for a longer period. 

Wrap Up

Now that you are armed with the buying guide you can go back to the reviews above and choose the best oil lubricated portable air compressor of your choice. Remember to settle on one unit that offers what you need. An oil-lubricated air compressor in general lasts longer since the oil reduces wear and tear of contact parts. 

All you need to do is to list your preferences and match them with the specifications provided to come up with an informed decision. Happy shopping!
