BUYER’S GUIDE
In this buyer’s guide section, we’ll look at everything you need to know regarding air compressors and which model is right for you.
Electric Vs. Gas Air Compressors
Air compressors are either electric or gas-powered, and the type of power plant in the machine determines the power and psi on offer. Electric air compressors are the most common type, but they have limitations on the range.
You have to use an electric model with an extension cord, and if there’s no power outlet anywhere nearby, your air compressor will be useless.
Gas-powered models don’t have the same issues with the range as electric models. Gas-powered air compressors allow you to wheel then around anywhere you go. Take them on job sites, or wheel them around the factory.
Typically, gas-powered models are the top choice for contractors, but many businesses use electric models as well. With a gas-powered model, the tank capacity limits the run time of the machine. However, this shouldn’t be a concern, as all you need to do is fill the tank and continue with your work.
Gas-powered models are also more expensive, and you can expect to pay a premium for having all that pressure available.
SCFM Vs. CFM – What’s the Difference?
When evaluating the candidates for your air compressor, you’ll need to pay attention to the two most important specifications on these machines. The CFM and SCFM are the factors that determine the volume of air the compressor moves during operation.
Cubic Feet per Minute or “CFM” specifies the filling rate of the compressor. Gases like air change weight and density at different temperatures and humidity levels.
Therefore, you’ll need to ensure your model can work in cold weather conditions if you live in the northern parts of the United States.
SCFM is a more comprehensive metric that stands for “Standard Cubic Feet per Minute.” SCFM measures the machine’s performance at a specific pressure and temperature, allowing you to compare the performance between models.
If you want the compressor to power pneumatic tools, then go for the highest number possible when selecting your machine.
Many homeowners and contractors make the mistake of thinking that larger tank size is the way to go. However, a large tank doesn’t mean much if the refill rate is higher than the maximum air draw of the compressor.
If the tank size is close to the SCFM or CFM rating, then go for the larger size tank. Larger tanks let you operate the compressor for extended periods when using pneumatic tools. You won’t have to wait for the tank to fill while using your air-wrench.
The compressors filling rate drops as the pressure inside the tank increases. This operation would make sense, since its more challenging to compress 150-psi than it is to compress the air to 50-psi, and the motor powering the pump requires a constant electricity source.
It’s critical to check the pressure measurement for evaluating the SCFM and CFM. Using this strategy gives you the best method for comparing the performance of air compressors.
Size of the tank
If we are using a piston-type compressor we should determine how large our tank should be. If we are operating it for low duty applications, i.e. when using a nail gun we can use one with a small tank.
But in case we want to work for extended periods of time a compressor with a large tank would be preferred.
Oil-Free Operation
When reviewing the air compressors, you’ll notice that some offer an “oil-free” operation. Oil-free compressors are the preferred choice, as they require less maintenance.
Oil-free models mean you don’t have to worry about oil leaks, keeping your home and workshop clean. There’s no disposing of old oil, and you don’t need to check the oil levels in the machine before operation. Let’s not forget about the environmental impact caused by dumping used oil.
Oil-based compressors also require you to replace the air dryers from time to time, increasing the maintenance costs associated with owning the machine.
However, oil-free compressors aren’t as durable as oil models, and they don’t offer you the same long service life you get from oil-based machines. Oil-free air compressors also tend to run louder than oil-free models.
Motor Power
When selecting your air compressor, make sure you also pay attention to the power output of the machine. The horsepower of the motor determines the power of the refill action of the machine. Look for machines with high horsepower if you’re a contractor.
Max PSI Air-Pressure
Another critical consideration for choosing your ideal air compressor is the psi the machine produces during operation. PSI, or Pounds per Square Inch, refers to pressure the compressor operates in a normal environment.
Air compressors require at least 90-psi to be effective. You should avoid compressors offering less than 100-psi. Contractors using pneumatic tools with the machine will require a minimum operating pressure of 125-psi to be effective.
Most air compressors operate in two stages. In the first stage, the machine builds the pressure in the air tank to around 90-psi. In the second stage, the machine boosts the pressure up to operating levels of between 125 to 200-psi, depending on the model.
Tank Capacity
The tank capacity refers to the volume of air stored inside the machine at full capacity. Tank capacity is only useful for contractors or workshops that have plenty of tools working at the same time through split lines.
If you buy a powerful machine with a high SCFM, then you don’t have to worry about the tank capacity, especially if you’re using the compressor for DIY projects.
In most cases, the compressor will be strong enough to replace the air as so as you finish using your tools.
However, you need to note that air compressors with larger tanks typically cost more. Therefore, if you’re a homeowner looking for the best machine to use around the house, don’t focus on tank size as a significant qualifying component of your air compressor.
Try to analyze the requirements of the air tools that will be used.
Consider the pressure and volume requirements of any tool. For e.g, Heavy-duty tools will require more pressure and thus more volume. If one fails to choose a compressor that is large enough for the intended use, the work efficiency will decrease to a considerable extent.
Choose between piston-type and portable compressors:
Piston-type compressors rely on a motor which builds up air pressure when it gets depleted. They store compressed air in tanks.
Portable compressors do not offer tanks and thus run continuously in order to deliver air.
Look at the horsepower (HP) of the air compressor.
Range for horsepower on an air compressor is between 1.5 and 6.5 HP which can be used for small and medium-sized applications. Air compressors with larger HP are usually reserved for industrial uses.
