DeWalt D55146 Air Compressor Review 2020

DeWalt D55146 Air Compressor

When it comes to having the best gear at the worksite, nothing compares to a high-quality air compressor. Many power tools these days run on air, meaning that you have to have a versatile and commanding machine to get the job done. Not only that, but an air compressor can help in a variety of ways, including cleaning up dirt and debris that comes from working.

So, with that in mind, let’s take a look at the DeWalt D55146 Air Compressor. As far as high-performance machinery goes, DeWalt is one of the best brands out there, and the D55146 is as powerful as it is durable. Whether you run a small shop or work on the go, this compressor will provide everything you need and more.

High Output

When you’re looking at different air compressors, the most important aspect is how much air it can generate. Most power tools have certain requirements as to the amount of air and the pressure needed to make it work, and the D55146 has plenty to go around. One of the biggest indicators of performance is the SCFM rating, which stands for Standard Cubic Feet per Minute. In this case, the DeWalt Compressor gives you 5.0 SCFM, which is higher than most portable units. It’s enough to power three framing nailers without any problems.

As for pressure, this machine has an operating psi level of 90, but it can max out to 200 if need be. Overall, you will get exactly the level of performance that you need, no matter what it is you’re doing.

Quiet Operation

One of the biggest issues with air compressors is the noise. This problem is especially problematic if you work in a small shop where you have to listen to the machine operating nearby. With a 1.8 horsepower motor, you would think that this unit would be loud, but that is thankfully not the case. In fact, the D55146 operates at only 78 decibels, which is about as loud as a vacuum cleaner. While it’s not exactly whisper-quiet, compared to many other similar sized machines, it is a vast improvement. You shouldn’t need ear protection when using this compressor.

Easy to Move

One of the biggest problems with air compressors is that as you get more powerful, they become much more cumbersome and harder to move. After a certain threshold, it is much easier to keep the machine in a fixed location, rather than hauling it from place to place.

While the D55146 is almost at that threshold, DeWalt has made it extremely versatile with how well you can maneuver around the job site. First, it comes with a thick, sturdy handle on top so you can grab it easily and take it wherever you want to go. Second, two ten-inch tires on the bottom help you get from point A to point B quickly and efficiently. Although the unit does weigh over eighty pounds, it’s still as portable as a smaller model. Also, the tires are rugged and air-filled so that they can go over almost any terrain with ease.

High-Capacity Tank

Another primary feature of air compressors that you should pay attention to is the size of the tank. The way that the machine works is that it draws air in and compresses it internally so you can get higher psi levels. With that in mind, the larger the reservoir, the more you can draw from and the faster you can work.

Smaller tanks have to refresh all the time because the air depletes rapidly. In this case, however, the D55145 comes with a 4.5-gallon capacity, meaning that you can use your tools with impunity and won’t have to wait for a refresh cycle every two minutes. That’s part of the reason why you can operate multiple devices at once, which wouldn’t be possible with a smaller unit.
