Key Features

Understanding the specifications of the Dewalt air compressor is essential if you want to make an informed decision. These specifications are factors that make the product one of the best on the market.

This unit may not necessarily be what you are looking for, but you will at least know from reading the specs what the product is all about. The highlights of the Dewalt 30-gallon capacity air compressor lie in the fact that it is user-friendly and allows you to work for longer consecutive periods.


The Dewalt 30-gallon compressor weighs 190 pounds. While this does seem a lot, it is nothing compared to the power of the machine. The weight also directly affects the portability of the machine. It is tougher to carry the machine from one place to another but if you only want to move it around in one area, you can do this easily. The rubber pads allow the machine to grip the surface and can be removed when it needs to be moved.


The air compressor is not noisy at all as it uses an oil-lubricated pump. Oil pumps tend to be much quieter than the other ones and run much more smoothly. Most of the issues in air compressors occur because the pump gets stuck or because it goes completely dry. With the oil pump, you can clean it up yourself and replace the oil. This is one of the easiest tasks in maintaining an air compressor and does not cost much. The refill process is so quiet that you can continue a conversation while the tank fills up.

Energy use

The Dewalt compressor is very energy efficient. It starts on electricity, which means you do not have to worry about the availability of gas or ever-rising gas prices. Electricity is available everywhere and, especially in your workplace, you will have an abundance of outlets.

Just plug in the air compressor to start it up immediately. You will save on costs in the long run because electricity is an affordable commodity.


You can use as many tools as you like with this air compressor. You just have to calculate the total pressure the tools need so that you do not overexert the pump. The Dewalt 30-gallon capacity air compressor provides a total of 155 PSI, which should be sufficient for most needs. If you are doing a task that requires one tool but a lot of pressure, you can remove the other equipment attached to the air compressor. After doing your work, give the machine time to refill. Once it has cooled down, it can be used again with any tool.


The air compressor can run easily for one hour if you are using it at an average power. It has a larger storage capacity compared to the other compressors in the market. Just be sure to let the tank fill up properly before you start it again. If you are not careful, you will wear out the tank soon and this can be dangerous for your work as well as the well being of the machine. Be smart in your investment. The 30-gallon air compressors are quite popular because of their industry-beating storage. However, you can shop air compressors by gallons.

  1. If you are using the machine for a lot of heavy work, you will have to give it a rest after use. The Dewalt air compressor will need at least fifteen minutes to cool down and recharge before using it again.
  2. The number of tools that you can attach to the air compressor depends on the pressure each tool needs. You have to calculate this pressure before you start attaching tools. If too many tools are attached at once, the results might not be satisfactory.


How do I check which tool is using the most pressure?

Checking which tools use the most pressure is an individual process. You must clip one tool at a time to the machine and let it run. The gauge will show you the amount of pressure it is using and then you can evaluate whether the work is satisfactory. To make sure that you are not overtaxing the machine, try out one too at a time. This is the easiest process although there are other ways to do the work.

How do I clean the Dewalt 30-gallon air compressor?

Maintaining the Dewalt 30-gallon compressor is an easy process. You will find a release valve on top of the machine. Whenever you are done using it and are about to pack it, open this valve. This releases all the excess air and vapors, leaving behind only the right amount of air pressure.

You can also use normal cleaning rags and brushes to clear the machine of dust. Do not use oil in the machine as it can mix with the air and cause damage to the pump.
