Frequently Asked Questions
Is a 20-Gallon Air Compressor Suitable for Business Use?
All of the compressors we’ve reviewed here are suitable for business and home use. Generally, it depends on CFM (Cubic Feet per Minute) requirements. Each air compressor indicates the max CFM (Cubic Feet per Minute) output it can generate.
Its CFM (Cubic Feet per Minute) output has to meet requirements so that each tool will operate without issue and efficiently. If you have an air tool based shop, for example, you will need about 5 CFM (Cubic Feet per Minute) per employee.
A 0.5-inch impact wrench will need around 5 CFM (Cubic Feet per Minute) at 90 PSI (Pound per Square Inch). Hence, your compressor’s CFM (Cubic Feet per Minute) should be higher than that.
It follows that if you have two workers operating these wrenches at the same time, you will need at least 10 CFM (Cubic Feet per Minute). The use pattern for these tools is to use them for about 25 seconds and then stop while the tier is changed. Body shop mechanics might need sanders and grinders for 25 minutes peruse.
You need to know how you’ll be using the machine because you need higher CFM (Cubic Feet per Minute) at constant usage levels.
What can I do with a 20-Gallon Air Compressor?
A 20-gallon air compressor can be used for multiple things if you need to use it for more simple DIY projects it will easily be suitable for this, or if you need to use it for business use or use in a commercial shop, then it will also be ideal for this too.
How long can a 20-Gallon Air Compressor Tank Last?
Air compressors have quite a long life and should be able to last you between 20 to 30 years, which is also equivalent to 40,000 to 60,000 hours of work.
One thing you should look out for is whether or not the air compressor comes with any key features; for instance, some guarantee that they can last up to four times longer, so this is always something you should look out for.
Size Does Matter
No matter which model you choose, take care of it, and it will take care of you for many years to come. If it runs on oil, let it run dry once in a while, and you’ll need a new one before you can ask yourself what you’ve done.
This is why oil-free options like the ones reviewed here are best. We hope this article has been helpful. Thank you for reading!
