What Features You Should look in 20 Gallon Air Compressor

1. Its the CFM that Counts

If you are not into air compressor terminologies, then let me tell you about CFM. CFM is actually cubic feet per minute. It is the measure of air delivered to your tool.

A 20-gallon air compressor can deliver 4 to 5 CFM to your tool.

In an ideal condition, an air compressor tends to supply 20% more air than your tool requires.

Sometimes it becomes quite problematic when your device consumes all of the air delivered and causes you to wait until the compressor catches up again.

For example:

if your tool uses 2 CFM at 90 PSI, then always pick up an air compressor that claims 3 CFM at 90 PSI.

2. PSI
It is the amount of air pressure pumped by a compressor out per square inch. It means that if you are using an air compressor continuously, it will drop its PSI and ultimately will need a tank refill.

You must be confused about the relation between CFM and PSI.

There is an inverse relationship between CFM and PSI. The more air you use, the less pressure will be left behind. In other words, the less air you use will result in higher air pressure in the compressor.

3. Size of Motor

The motor of an air compressor is the main part that cannot be ignored. It works in compressing air into the tank and refilling.

Always look for a good quality motor for air compressor. Also, keep in mind the affordability ranges of oils and fluids that you will utilize in the maintenance of the motor to avoid wear and tear.

4. Tank Size

If you are searching for air compressors, you may have noticed that each air compressor has a different tank size.

Tank size does not interfere much with the efficiency of your air compressor. However, larger-sized tanks can hold a sufficient amount of air as compared to a small-sized tank of air compressor.

One of the massive benefits of a large size tank is that it can fluently power your tool with air without fear of need of refilling the tank.

Larger tanks have pre-compressed air that supplies your tool continuously without causing you to wait for the air to be compressed.

Electric VS Gas

While analyzing the features of electric and gas air compressors, you will end up with the pros and cons of both.

Gas air compressors will deliver enormous power to your tool but produces so much noise. This will have bad effects on where you want to use it.

Electric air compressors, on the contrary, are way quieter. You can easily use it wherever you intend to use without any disturbance in the vicinity.
