How to Pick the Quality Air Compressor?

With the world gradually knowing about the best air compressors' never-ending usage, one common question is in the air. That is, what exactly are the criteria to select a decent one? Worry not; we’re here to help.

Air Pressure

You’re working with the air here; it’s only natural that checking the air pressure is mandatory for you before selecting one of these machines. There is a standard for measuring pressure, commonly known as the PSI. Generally, you need at least 90 PSI for an air compressor to work properly.

More pressure, the better might not always be the case here, but if your tool has two stages where the first one can build up to a PSI of 90 and the second one can build up to 175- you’re all okay with the pressure.

Just be sure to check if there are obstacles in the hose- because that can be a major issue in your compressor reaching its full potential.

Horsepower

Depending on your preference and usage, you can determine exactly how strong your air compressor should be. Unfortunately, many of the manufacturers often overstate the horsepower while advertising their products. But we have an extensive process that can help you measure the horsepower accurately.

All you have to do is check how much electricity it consumes. For example, a basic five horsepower motor is supposed to consume up to 24 amps or 220 volts of electricity. That should be more than enough for you to do basic household or DIY works.

However, if you prefer to do more, you can always pick air compressors with more capacity.

Oil-free

This here is a very common debate between people working with air compressors. Both Oil-free and Oil-lubricated ones have their advantages and disadvantages, and it all depends on your jurisdiction at the end of the day. All we can do is put in the pros and cons of both the types; the rest is all up to you.

Oil-free air compressors are a fantastic companion for someone who cares about the environment or someone who doesn’t want to spend a lot on these tools. Moreover, oil-free ones are cheaper, easy maintenance, and definitely environment friendly—no risk of oil spills on the inside of the air dryer, no extra expenses.

However, Oil-lubricated air compressors are relatively expensive, work quietly, and are able to do the work much more efficiently. It’s faster and quieter, but at the same time, the oil can cause all the trouble in the world, as aforementioned.

Size of Tank

Let’s be honest with this; tank size doesn’t really matter much when it comes to air compressors, mostly because nobody stores air inside the compressor; it is for instant actions mostly. Having said that, the tank size of your tank will be essential if you want to consider the costing. Bigger tanks cost more than the smaller ones.

Bigger tanks can hold on to a lot of compressed air, but unless you need a lot, lot of compressed air for massive initiatives, you don’t really have to spend that extra buck for a big tank. However, sometimes smaller tanks might stop midway; this is never the case with big ones.

Portability

The larger the compressor, the lesser the portability. While this is a very common thing to understand, the issue isn’t as big as it seems. Unless you’re using one of those gigantic 80-gallon compressors, most of the relatively smaller ones come with wheels and pneumatic tires.

Starting from 3 gallons, we can safely say that 30 or 20 gallon air compressors are easily portable, be it with wheels or some other mediums. Some of these tools also come with handles, so portability is often not a big deal with them. However, make sure the size of your machine actually reflects on the usage.

Noise

Like we’ve said before, noise can be a major issue if you’re living in any neighborhood, and you tend to use the compressor on a regular basis. If your tool is an Oil-free single state one, it will indeed cause many sounds, and your surroundings won’t really be happy.

Now you can take care of it in a couple of effective ways. One, you can opt for the much quieter, Oiled compressors. But they’re expensive, so another choice for you might be to find a bigger place that will muffle the sound.

Your garage can be a brilliant option here. Do understand that bigger compressors make more sounds- so you should keep that in check.

How to Install an Air Compressor? 

Air compressors work by receiving natural air and shrinking its volume so that the air becomes highly pressurized. You have to proceed with caution because a simple malfunction on your part might start you off the wrong foot.

Accurately installing your air compressor is a step in the right direction. Today we are here to answer your question, "How to set up an air compressor in the right way?"

Select the Spot 

Firstly, you have to determine the adequate room needed for your air compressor to cool off. If it doesn't have enough room to vent, the compressor will run hot. Ensuring more space for the machine goes a long way. Allow the compressor to exhaust, so it doesn't trap hot air within the frame.

Place It Near a Power Outlet 

Air compressors need to run on electricity, and it's important that a power outlet is near the workspace. Make sure that you don't give the compressor too much amperage, which might lead to a failure. 6 Gallon pancake-style compressors are compatible with regular household sockets.

Choose the Right Hose Length 

If you invest in a long air hose for use in your garage, there's always a chance of pressure loss. Your compressor might deliver the right PSI level, but going through a long hose will create less pressure on the tooltip and decrease pneumatic tools' efficiency. A 50 feet hose for a home garage is of the perfect length.

Add Filters and Separators 

Eliminating moisture in between the tank, inlet valves, and pistons call for a good filtration process.

Since oil can reach the tank from the motor and create an imbalance, we advise you to install a filter to the air outlet. It will stop lubricants from affecting your workpiece. Moreover, sanding, blowing, and spray painting will be of premium quality.

Electric vs. Gas Air Compressors

To be very honest, if you consider performances or efficiency, there isn’t much difference between the electric and gas air compressors.

But you’re not looking for an average compressor that will ‘just do’ the job, right? You’re looking for the best option available, and this is why you need to know the differences between Electric and Gas air compressors.

Gas Air Compressor 

Stating the obvious to start with- these tools are run by gasoline. While it is true that with the resurgence of electricity, spending bucks on a machine that runs on gas sounds a bit ridiculous, but there are tons of positive aspects to it.

First things first, electricity might be scarce in places, and without a proper electrical hookup, the electric ones would cease to exist.

Technology might have advanced a lot, but at some point, one might have to get back to the analog way, and when there’s no electricity, a gas compressor might be your savior.

These tools work with unloader valves that depend on the pressure inside, unlike the automatic system. This means it can work on a continuous basis- thereby being a good option for larger projects.

However, there’s one catch to this otherwise useful air compressor. They can’t be used indoors. The fumes, the noise, and the overall hassle are just too much for indoors.

Inhaling these toxic fumes can prove to be dangerous, and working with highly flammable gasoline indoors is always risky. These machines aren’t quite portable either.

Electric Air Compressor

It’s no surprise that electric compressors are more available on the market, mostly because they’re much, much easier to use with a minimum amount of hassle. A convenient and cost-effective tool, electric compressors are widely popular because electricity is more than available now in urban and suburban areas.

Contrary to the bulkier gas air compressors, the electric ones are portable, lightweight, and highly versatile. Coming with different designs and shapes, the compressor looks lucrative as well.

There’s this start-stop automatic switch in it that can shut the motor down if the pressure reaches its limit. The same will occur if the pressure drops below a certain value.

A very common issue with these electric machines is that extension cords won’t work with them. This is why if you consider outdoor works, it’s not very feasible.

It doesn’t matter how powerful the air compressor is; it is useless without a plug-in place. For heavy-duty jobs that require constant pressure, these electric devices tend to underperform.

The following discussion comes to one conclusion- there are no clear winners here, but you. It all depends on where you want to use it. For heavy outdoor compression tasks, gas-based air compressors are a must. And for basic indoor work, you choose the electric one—no in-between.

Air Compressor Cleaning and Maintenance

Keeping an air compressor for running air-powered tools at the garage is not a luxury. If Brad Nailers, angle grinders, nail guns, air ratchets, and hammers are in your daily vocabulary, you need an air compressor to drive these hand tools.

As for the construction crews, this pneumatic machine will help you run jackhammers, impact wrenches, sanders, and many more.

You have to run frequent maintenance checks on your air compressor to prevent clogs, over-heating, corrosion, and pressure drops. Catch up on our air compressor maintenance tips right now!

Check for Leaks 

Detecting air leaks is difficult because there is no smell to it. You can listen for a sound or use soapy water to condensate traps and hoses. If you see bubbles form, it means that there's a leak. Oil leaks will be visible.

You can grind the leaky spots, which are most likely to occur around the drain and connection points. Up next, you may use a brazing torch and patch it up.

Monitor the PSI Output 

The pressure (PSI) level that you get on the tooltip should be exactly what you chose on the regulator knob. If you see lower PSI levels on your pneumatic tool, checking for leaks and worn out filters is an excellent place to start.

Too high of an incoming voltage and amperage is also not something your air compressor wants. Don't forget to test the cooler quality for long-lasting performance and an impressive duty cycle.

Unclog Intake Vents 

You have to replace hoses, intake vents, and attachments when they have corroded. If not, there will be leaks that can stress the motor. We will also suggest that you keep the connection points free of dirt and grease.

Change the Pump Oil

Excessive grime, sludge, dirt, and discoloration of the pump oil sample means that it's time for an oil change. It will help you avoid many device failures at crucial times. After you've exceeded several hundred service hours, fully replace the pump oil. It keeps the motor healthy.

Oil vs. Oilless Air Compressors 

This here is a very tricky debate with no clear winners. As discussed before, even though Oil and Oilless- both have similar tasks, the way they do it is quite different. To put things into simpler measures, the work of compressing air is done by a piston chamber, and to keep it work smoothly and efficiently; it needs constant lubrication.

Moreover, this lubrication is done in different ways in the two types. For Oiled compressors, they lubricate the piston with oil directly, whereas, for the Oilless ones, permanent lubricants like Teflon are used. Both these processes have their positive and negative aspects, time to discuss them.

Oiled Compressors

If you want a smooth, quiet business, this should be your pick. Oiled compressors are high-maintenance, expensive, and efficient tools that you can use for a long, long time.

Is it less portable? Yes. Is it more complicated than the oil-free ones? Yes. But at the same time, it is way more durable due to the continuous maintenance and provides you premium service.

Oil-less Compressors

If you want a compressor that is cheap, portable, and very low maintenance, then you really should give this one a go. These compressors are lightweight machines with very few complications and easy usage.

However, it’s not that good in the long run. The sound is very loud, and at some point, the working particles might wear off. Still, it is a feasible option for irregular users.

Our suggestion for you is that if you need the compressor for daily use, then the Oil lubricated one would be a more peaceful option for you and your neighbors. However, if your goal is to use the tool very, very occasionally, in that case, a simple, inexpensive Oil-Free compression would make a good option.

Frequently Asked Questions

What CFM do I need for air tools?

CFM is the volume of air that your air compressor delivers at a fixed PSI level. Air tools such as paint sprayers, nail guns, and crown staplers don't require more than 4 CFM.

For driving pneumatic tools for home use, a pancake compressor suffices. But when it comes to industrial applications, you may need 30-150 CFM depending on your power tool.

How do I increase the CFM of my air compressor?

The most effective way to increase the CFM of an air compressor is to dial its regulator down. You have to remember that the airflow rate and the pressure are negatively proportional. It means that when you have less pressure in the air tank, the CFM will increase accordingly. So, the lower the pressure, the higher the CFM.

How can I make my garage compressor quieter?

To make your air compressor quiet, you can install noise blankets or noise barriers. This way, you don't have to change the motor. You can also try putting the machine in an enclosed area or put concrete blocks around it.

Installing a decent muffler on its intake port also decreases the noise level of an air compressor. If you have an extension cord, transfer the machine far from your workspace.

How often should I change the oil in my air compressor?

You must change your air compressor oil, or else it will lose its optimum viscosity levels. Changing the compressor oil once a year is what we generally advise. But if you use an industrial air compressor, you might need to change it more frequently.

How long should an air compressor last?

Good air compressors are very durable, and their average life expectancy is higher than any motor-powered electronics. An oil-free compressor will last approximately 40,000 hours. Provided that you ensure proper maintenance, your air compressor should give 10 to 15 years of service.

Can a pancake compressor run a framing nailer?

Yes, any pancake style compressor that delivers at least 2.6 SCFM and has 150 PSI pressure can run a framing nailer for both home and semi-professional use. Any 4 to 6-gallon BOSTITCH or DEWALT pancake air compressors are suitable for framing nailers.

Do air compressor tanks explode?

Air compressor tanks can explode for a few reasons. Manufacturing defects are hardly the cause. The most common reason why air compressor tanks explode is the build-up of rust inside the tank. It happens when you don't drain the tank daily after use.

Is a two-stage air compressor better than a single-stage?

Two-stage compressors are best for industrial applications and construction processes. They are better than the single-stage alternatives and efficiently run at a higher CFM.

Are air compressors dangerous?

Air compressors run hot and produce high noise levels. Apart from that, air compressors are safe to use. You have to drain the tank daily and pay attention to its duty cycle.

Conclusion

From driving an impact wrench to firing a nail gun, the uses of an air compressor are plenty. However, choosing the best air compressor was an easy task. Its flow rate, duty cycle, motor quality, and ultra-quiet operation set it apart from the rest.

We are talking about the WEN 2289 10-Gallon air compressor. It delivers 4 CFM at 90 PSI, offers an extended duty cycle up to 120 minutes, and is equipped with a powerful 1.5 HP motor.

Porter-Cable Oil-Free UMC Compressor is our second favorite. Although its flow rate is slightly lower than that of the Wen compressor, it offers an additional 30 PSI Bonus air to avoid pressure drops. It provides 3.5 CFM at 90 PSI, which is pretty close to our winner.
