The DEWALT D55146 is a 4-1/2 gallon, 225 PSI air compressor built for professional trim nailing and general jobsite air. Its high-pressure tank stores more usable air, while the 5.0 SCFM pump recovers quickly, so you stay productive when running a finish nailer or air stapler. The maintenance-free, oil-free pump eliminates routine checks, and the vertical stand plus collapsible handle let you tuck it away in tight spaces between jobs.
Large 10-inch non-flat pneumatic tires and a balanced carry handle make the D55146 easy to move around the site. When the workday ends, the unit stands upright to cut its footprint in half. A protective metal console shields the 2-inch gauges, couplers, and regulator from jobsite bumps.
Residential painters, carpenters, and remodelers who primarily use brad nailers, finish nailers, and air staplers will get the most from this compressor. It’s also a strong choice for gas or diesel mechanics using air chips or nozzles, provided you stay within the 225 PSI rating. If you need a quiet, portable compressor for smaller trim projects, the DEWALT D55146 is a dependable workhorse.
225 PSI max tank pressure provides industry-leading usable air and consistent nailing performance.
5.0 SCFM at 90 PSI recovers quickly, keeping up with continuous fastening tasks.
Oil-free, maintenance-free pump eliminates oil changes and service intervals.
Vertical stand and collapsible handle cut storage space in half.
10-inch pneumatic tires and high-visibility console make job site moves simple.

Pancake compressors are common for trim work, but the D55146 gives you more usable air at a higher pressure. The 225 PSI tank provides a larger reserve, so the motor doesn’t cycle as frequently. If you’re doing extensive trim installation or using multiple air tools, the faster recovery and larger tank make a noticeable difference.
Many job sites have limited floor space. The D55146’s vertical design lets you lean it against a wall or corner, taking up a fraction of the floor area of a standard horizontal tank. The collapsible handle also means it can ride behind a seat or in a van without jamming.
It is ideal for finish nailers, brad nailers, staplers, air blow guns, and other tools that operate within 225 PSI and 5.0 SCFM at 90 PSI.
Yes. The vertical stand allows the D55146 to rest upright, and the collapsible handle saves space when storing.
No. The DEWALT D55146 features an oil-free, maintenance-free pump that runs without lubricant.
It operates at 78 dB, which is quieter than many conventional compressors and comfortable for residential or shop use.











Small but powerful.
Fills my tires fast. The wheels are handy.
I needed an air compressor for my nail gun and this one is compact enough for my tiny garage. It pumps up to 225 psi quickly. The oil-free motor means no mess. It's a bit loud, but not unbearable. The wheels actually help when moving it around.
I frame houses and this compressor keeps up with my nailers all day. It's heavier than the pancake style, but the wheels and handle make it easy to move. The 4.5 gal tank gives you plenty of reserve. The 225 psi lets it recover fast. The only issue is the noise, but that's expected. Great value.
Works good, but the regulator is touchy. Other than that, fine.
I've had many compressors over the years, and this is a good one for the price. It starts easily, even in the cold. The oil-free design is nice because I don't want to mess with oil levels. It runs a bit loud, but I wear ear protection anyway. I use it for filling tires and occasional air tools. Recommended.
Great little compressor.
The pressure is more than enough. It's heavy but stable.
I do mobile detailing and need to blow out cars. This fits in the trunk and has enough power to run my air gun. It takes a little while to fill the tank, but it's not bad. The vertical design saves space. The rubber feet keep it from sliding. Good product.
Works well.
It's everything they say. Loud but powerful.
