How To Buy The Best 4 Gallon Air Compressor
Power And Pressure
The power and pressure of a compressor is measured by CFM and psi as the common metrics. CFM is the amount of airflow while PSI is the amount of pressure inside the tank. A 90 psi and upwards is enough for most compressors. The CFM is the most important factor to look for because it shows how much air is being delivered.
If you will be carrying a compressor from place to place, then portability should be considered. It should be lightweight and comfortable enough to carry around.
Easy Tank Drain
This is a vital factor that you ought to look for in every compressor. An easy tank drain ensures you get rid of all water logged in the machine that might otherwise undermine its effectiveness.
Accessories are crucial but you have to look for what you need. An air compressor should come with all the accessories that you require for your tasks and applications.
A good air compressor should not be too loud for the comfort of the people around. Some machines are louder than others. The noise levels should at least range between 60 decibels and 90 decibels. The lower the better.
I hope the list above will be helpful to you when searching for a good quality and reliable 4 gallon air compressor. The final choice entirely depends on you.
