Best Air Compressors Buying Guide
Air compressors can be used for several purposes: inflating tires or specific tools in your workshop. Also, air compressors come in diverse sizes and shapes, such as the ones reviewed in this article. Choosing one of the compressors outlined in this piece will save you money and help you make the best choice.
Knowing what to look for when scouting for air compressors will help you further narrow down your selection. This section will list some essential tips that should help you make an informed decision! Let's get started.
What Makes Air Compressors Unique?
Air tools are generally smaller and lighter than those made using mains or battery power because they usually do not need a heavy motor or battery. While they're powered with an electric source, the energy is at once converted into kinetic energy, similar to how a combustion engine works!
The use of electric-powered tools is discouraged in some places due to the risk of electrocution or electrically triggered fires. Air compressors are generally safer because they don't use any power unless they're on and running which means little can go wrong electrically. If your work environment is such that it has combustible gases, the compressor will help keep working conditions ideal!
Another unique benefit of air compressors is that they are more affordable than hydraulic or electric tools. Furthermore, air systems are cost-effective to install, and they have lesser maintenance requirements.
What Should You Look Out For When Buying Air Compressors?
Before you go out hunting for an ideal air compressor, there are a few things you should be on top of. With a plethora of options out there in the market, choosing the right one requires being armed with the right level of information!
Portability vs. Tank Size
If you get a bigger tank size, you will be able to operate different air tools simultaneously for an extended period before the pressure falls to refill more air. But with more giant tanks, the compressors are bulkier and heavier, making it quite complicated to maneuver. Using a smaller tank will limit your ability to operate for long because it stores less air. However, smaller tanks offer more portability or movability because you can attach rubber wheels, making them easier to convey around. The point is, weigh your requirements well so you can pin on the right air compressor accordingly!
Free Air Delivery
Free air delivery determines the air volume produced by the compressor, and it is measured in CFM. If you are someone that has many pneumatic tools and you want to use multiple devices at the same time, it is required that you stack up the CFM requirements from the air tools and ensure that your compressor-free air delivery surpasses or equals it for a seamless experience.
Petrol vs. Electric Compressors
Ideally, it would help if you used a petrol compressor outdoors or move the compressor from one worksite to the other where there is a shortage of electricity. But note that it is not entirely safe to use a petrol compressor in an enclosed area for the sake of safety.
The electric motor compressor is usually the top pick for most industries because it costs less to buy and maintain. The electric option comes in triple or single phase, so you be sure of the power source you are using.
Each PSI compressor comes with a different PSI level. The PSI will determine the level of power the air being produced is. For instance, if the air tool comes with a requirement of 150PSI, the compressor needs to pressurize a minimum of 150 PSI for it to optimally. You also need to ensure that your air tools are not working with an excessive PSI because it can adversely affect your air tools.
The duty cycle represents the ratio between when your compressor is cooling and when it is being operated. If you want to optimize the compressor, you shouldn't let it work for more than 60% of the time. Also, if you observe that your compressor quickly runs out of air, you may need to get a bigger tank!
Ability To Withstand Moisture Problems
The longer you use your compressor, the hotter it will become, leading to increased moisture problems. When the air gets compressed, it heats up, and water gets released when it is compressed. Also, when the air becomes hotter, the condensed water from the system will increase, thereby causing more moisture in the compressor. The ideal way to eliminate the moisture issues associated with your compressor is to buy a larger one to reduce the workload.
Compressor Life Expectancy
One other important factor you should consider when selecting a compressor is life expectancy. You may become disappointed if you buy a compressor that only lasts for half the time it is promised. There are several brands of compressors out there that are created to last more than five times the span of regular compressors.
You should find out the life expectancy of the compressor before you pay for it - we suggest scouring through customer reviews.
Best Air Compressor FAQ
Q: How can I know the CFM of my compressor?
A: To correctly calculate the CFM of your compressor, multiply the tool's required SCFM by 1.2. This will give you an accurate estimate.
Q: How do I maintain an oiled air compressor?
A: You will need to periodically change the oil as neglecting the maintenance will lead to irreversible damage and affect the product warranty.
Q: Which is quieter between oil-less and standard compressors?
A: The standard compressors are usually quieter than the oil-less option. The reason for this is that they are liquid lubricated.
Q: What tools can an air compressor run?
A: There are loads of air tools - this includes nail guns, impact wrenches, paint sprayers, and more! You'll need a good air compressor to run everything. In most cases, you'll find an air compressor powering the tools that fall in the 10 - 110 CFM range.
