How to Look to Pick the Right Shop Air Compressors
Now that the reviews are done and dusted let us get on with some valuable pointers. This section will provide some key aspects you could look for when purchasing the best shop air compressor for the money.
So, read through this section to get the best out of your money!
Low Noise Levels
Noise levels are a critical aspect of any air compressor. Extreme noise can cause irreversible damage to the ears.
The human ear can usually work correctly under 80 dB of noise, and anything above that starts to feel uncomfortable.
When buying an air compressor, always inspect the maximum noise level it can attain beforehand. Anything below 70 dB is good to go. However, even better would be below 60 dB.
This should not be hard to find, as many models are being designed to be as quiet as possible.
Portability is a necessity if you are on the move a lot. A portable air compressor certainly makes life easier and more convenient.
Portable compressors weigh between 30-50 pounds at most. Beyond this mark, it becomes slightly difficult to transport them.
Also, check if the air compressor is equipped with wheels or a pulling handle, as these would make it easier to drag it across.
Decide On the Tools to Be Used
This is perhaps one of the most important aspects of getting the best budget shop air compressor, and a wrong selection may prove to be beyond costly.
As a guideline, you should always remember that high power, high-performance tools require more air pressure to operate. Hence, if you are using a compressor for industrial or factory level applications, you would need more pressure, usually over 120 psi.
The opposite is also true. For operating lightweight tools, such as a nail gun or something similar, a low-pressure compressor will work just fine.
CFM stands for cubic feet per minute, and it is essentially the amount of air the compressor can pump out in a minute.
A high CFM rating indicates that the compressor can pump out air very fast and in large quantities too.
Moreover, the CFM rating once again depends on the type of tool you are going to use. Most devices generally require 4-6 CFM, but heavy-duty tools like grinders need above 8 CFM to work correctly.
It is thus wise to make sure you have a good idea of the CFM rating you need for the job at hand.
The pump of old model compressors usually required oil to operate. While many new models do not have that requirement any longer, there are still some models that do.
If possible, always go for oil-free compressors, as these types of air compressors are way easier to maintain. They require zero maintenance, as you do not have to check on oil levels from time to time.
They also save you some cash, which would otherwise go into buying oil at exorbitant prices.
Like any other machine, a compressor requires a power source to operate and work efficiently. This power source could be in the form of electricity from the mainline, a battery, or fuels, such as diesel and gas.
Out of all power sources, electricity-powered compressors are the right choice if you live in an urban area or if your workspace does not have any electrical issues.
It is much cleaner for the environment and takes up less cash to power. Battery run compressors are the right choice if you travel around a lot and take the compressor with you for work.
You may not always have a power source nearby, in which case the battery can provide useful energy. However, the battery itself needs to be charged and also has a definite lifespan, so be aware of that.
Fuel-run compressors are still standard in many parts of the world where electricity is scarce. They get the job done, but at a huge tradeoff. The emission released from the compressor is very harmful to the environment and can be poisonous to breathe in.
Hence, a fuel-powered compressor cannot be placed indoors at any cost and should always be placed outside.
Benefits of Shop Air Compressors
Using a best air compressor can have several benefits. Here, however, we will discuss the most common ones.
Air is Cheap
The most significant benefit of using compressors is that they use air. Air, unlike petrol, coal, or gas, is completely free!
This means no buying costs, taxes, or losses. Air is also incredibly easy to acquire since it is all around us 24/7. Even if you need to fill up on air for a refill, it will cost you significantly less than the same amount of petrol or oil.
You Can Clean with It
Contrary to what many people think, air compressors are not just for refilling tires or powering tools. One primary use of air compressors is cleaning.
The high-pressure air that exits the compressor can rid of the toughest stain, dirt marks, and even debris. This air can be used to clear roads, pavements, and sidewalks.
More importantly, there are no harmful gases involved during operation or no usage of toxic solvents and chemicals.
Just direct, simple air to get some cleaning done.
Using Power Tools
Another use of air compressors is to operate power tools. Nowadays, many power tools like nail guns are engineered to run with air.
The reason for this is that battery or electricity-powered tools are more expensive and ultimately end up consuming valuable power. They can also be a bit more unsafe to use.
However, with air compressors, you can operate heavy-duty tools like nail guns. You will be pleased to know that the performance will be the same, and you will not even notice any difference.
Carry Them Anywhere
Shop air compressors are lightweight and hence portable. If you move around a lot, you can just take one in the back of your car and get going. You can also use them anywhere you go.
Frequently Asked Questions
So it is time for the FAQ section of this article. After all that reading, you probably have some questions you may want answering.
Worry not. This section will address the most common inquiries and provide concise answers.
How Many Amps for a Shop Air Compressor?
This is a common question and one that has more than one answer. Before that, it is essential to know that the amps a compressor uses are dependent on the type of function it performs.
Heavy-duty compressors operate on a voltage rating of 220 V. These have larger motors and rotate at a faster rate, which is called the RPM.
These heavy-duty air compressors run on 23-24 Ampere (amps) of current. Note that this is the standard requirement and is the general case.
For light or medium compressors, the voltage rating is about 110V. These compressors have smaller motors and thus have to work harder to keep the components running.
These air compressors draw in 33 amps on average. The larger requirement is because the motor needs more power to run things smoothly, as it is comparatively smaller in size than the heavy-duty compressor motor.
How Do I run Air Lines in My Shop?
Running an airline through your shop is easy if you get the right things to work with. First off, you need steel piping, about 0.75’’ in diameter.
For compressors, most of the pipes will be threaded in advance, so use an adjustable wrench to join them end to end.
If any part needs to be cut off, use a tube cutter and not a knife. By joining the tubes end-to-end, you will have one end fixed to the air filter set to the compressor.
The other end will be fixed to an air supply.
How to Plumb Shop Air Compressors?
This is more of a multiple-step process, but we will try to explain the process as briefly as possible.
First off, you have to decide what you will use the compressor for. Based on the type of work you hope to achieve, set out the compressor in a place where its noise will not cause disruption.
After the initial set up, connect and assemble the piping system. This procedure is outlined in the previous question, and it requires you to create a piping network across the room.
Next, make sure that a filter is installed before the compressor. The filter will remove dust, and thus clean air will go into the compressor.
Next, before connecting the filter and piping system, you will need a rubber hose. The diameter of this hose should be based on how much air you need to feed into the compressor. This is further dependent on what the compressor will be used for.
Make this decision carefully. After that, connect the rubber hose to the piping system on one end and the filter on the other end. Tighten the attachment point with a wrench to ensure air does not leak out.
What Does the Dryer Do in My Shop Air Compressor?
The primary purpose of the dryer is to dry the air. Compressed air can contain water, and this water, if allowed to accumulate, would damage the compressor.
Hence, a dryer ensures the air moisture-free, keeping the compressor safe.
How to Make Shop Air Compressors Quiet?
Air compressors can make quite a lot of noise, and despite newer models being made quieter, they can still disrupt the workspace.
One thing you can do to make them quieter is to ensure the bearing are well lubricated. Usually, bearing tends to make a lot of noise when they vibrate due to friction.
Well, lubricated bearings will solve that issue.
Reposition Air Intake
Compressors generally make the most noise when taking in air. This is a lot like a vacuum cleaner sucking in dirt.
If possible, position the air intake valve outside the workplace. This will reduce noise levels drastically. However, make sure that connections are secure.
Get a Silencer
A silencer is a great tool that works well on cars and bikes. It can also be modified to work on compressors.
Moreover, the silencer should be fitted on the air intake valve, and if fitted correctly, will result in a drastic reduction of noise.
Put the Compressor in a Different Room
This is the final thing you could do, and it is to place the compressor in a separate room entirely. This would also mean that you will need more piping to get the compressor from a distance.
But, this is the last resort if all other methods don’t work out.
So that concludes our review of the best shop air compressor. We saw that the C2002 has a high capacity, high pressure but generates noise. The 6 gallon air compressor from Craftsman and the BTFP02012 have similar specs, but the BTFP02012 edges out in quieter performance.
Dewalt's compressor packs quite a punch in terms of pressure, and the 8010 from California tools ticks many boxes in terms of runtime, capacity, and low noise levels.
Finally, the JC10 is perfect for trips or tours and is the most compactly built of the lot.
However, based on raw performance, we would suggest the 8010, as comes with accessories, a low noise level, a large tank, and more than enough pressure, making it the perfect fit for any workplace.
