There are many different types of air compressors out there and they all work differently. This can make choosing one difficult, especially if you don’t know what to look for. The best way to choose an air compressor is to determine your needs and requirements. This will help you decide what size air tank, CFM and PSI capacity is needed to power your tools effectively.
Power
The power of an air compressor is determined by three primary metrics: horsepower (HP), pressure (PSIG) and capacity (CFM). It’s important to know these numbers before you purchase an air compressor. For example, a framing nailer will require much more HP than a tire inflator. This is because the tool requires a high PSIG to push the air through its pneumatic system, which uses pressure to drive tools like hammers and screwdrivers.
Size
The size of the air compressor unit is often a key factor. It should be big enough to support the tools you plan on using, but not so large that it causes pressure drops and inefficiencies. To get the right size for your needs, look at what type of tools you intend to use and how often. Then, calculate the CFM and PSI required by your tools.
Weight
It’s important to consider the weight of the component parts. This isn’t a problem for the homeowner, but it can be a challenge for contractors and commercial users alike. A high-end unit may weigh in at over 250 pounds, while a mid-range model can top out at around 80. Copper, which is used to construct the evaporator and condenser coils, accounts for much of that weight.
Noise
Air compressors are noisy machines that generate a lot of vibration. This is largely due to the fast-moving parts of the machine, as well as residual vibration from the suction process. Thankfully, there are some things you can do to make the noise of an air compressor less of a nuisance. The first thing you can do is move the intake pipe outside of your garage. This will help to significantly reduce the sound of the air compressor and allow it to run quietly. Additionally, you can install earplugs to help protect your ears from the noise as well.
Warranty
The warranty is one of the most important things to look for. It can make the difference between having to pay $3,000 for a repair, or having it repaired free of charge. The warranty on a compressor should cover both materials and workmanship. This is a good sign that the air compressor remanufacturer you are considering is taking pride in their product and will stand behind it.
