What’s an Air Compressor?

Basically, the job of an air compressor is to contain air whose pressure exceeds that of the atmospheric air on the outside.

You can use this air to operate many tools of various sizes and functions.

How Do portable Air Compressors Work?

Air compressors consist of 3 parts

The drive: Provides the compressor with the power to propel its pump. It can be a gas engine or an electric motor.

The pump Uses the energy from the drive to suck in atmospheric air and compress it until it reaches very high pressures.

Through a discharge tube, the compressed air is sent to the storage tank.

The storage tank: Equipped with a check valve that stops the compressed air from escaping or applying back pressure on the pump.

How to Pick The Right portable Air Compressor for Me?

There a couple of things to consider when you’re buying an air compressor:

Gasoline or electric-powered?

Gasoline-powered ones are more suitable for outdoor work where the noise and ventilation wouldn’t be a problem.

An electric-powered compressor would be better for indoor jobs where there wouldn’t be much ventilation and airflow.


This indicates how powerful the motor is and consequently how high the pressure would be. It’s also an indicator of how effective your air compressor will be at providing your air tools with power.

CFM (Cubic Feet per Minute) or SCFM (Standard Cubic Feet per Minute):

This number indicates the volume of air that your compressor will be capable of delivering at specific levels of PSI.

As the PSI decreases, the CFM increases, and the higher the CFM is, the more your compressor will be suitable for heavier duty jobs.

Storage Tank Size:

How much air can your device compress and store? Don’t settle for one that is less than 4 gallons. The average would be 6 to 8 gallons.

Decibel rating:

Air compressors can be used continuously for extended periods of time. This is why you should try to get one with a low decibel rating so that its noise wouldn’t bother you.

Why Are There Different Shapes of portable Air Compressors?

It has to do with functionality. On twin tank compressors, the tank that’s further away from the compressor remains cooler for longer periods.

And of course, on twin ones, you’ll be able to store more air and therefore will be able to run your air tools for longer periods.

Final Thoughts

If you’re looking for the best portable air compressor, you’re definitely going to find it on that previous list.

You should opt for the California Air Tools CAT-1P1060S Light & Quiet Portable Air if your main concern is getting a budget-friendly model. It’s also a very quiet and portable choice. However, its CFM is inferior to many other choices on the list.
