The DEWALT D55140 is a compact electric air compressor that packs enough 135 PSI performance to drive trim and brad nailers, while the 1-gallon tank keeps it easy to carry. Made in the USA, this compressor is a practical choice for finish carpenters, remodelers, and homeowners who need a reliable air source without dragging a 30-gallon tank around.
A 2.6-amp motor powers the pump and recharges the 1-gallon tank quickly for short nailer bursts. The small tank is ideal for trim work, pin nailers, topping off tires, and other jobs where you need short bursts of air rather than continuous high-volume flow. Its lightweight design and built-in handle make it easy to move from room to room or up a ladder.
If you mostly use 16-gauge finish nailers, 18-gauge brad nailers, or inflate tires and sports gear, this compressor matches your air demand without being oversized. For continuous high-demand tools like framing nailers or air sanders, choose a larger tank compressor.

If your work centers on trim nailing, 1 gallon is usually plenty. A trim nailer uses a burst of air, and the tank recharges between nail placements. For continuous-use tools, choose a larger tank. This model is best for mobile finish work where a heavy compressor would slow you down.
Finish and brad nailers are intermittent tools. They don’t need a huge air reserve the way framing nailers do. That makes the D55140 a natural fit for baseboards, casing, and shoe molding.
Thanks to the carry handle and compact footprint, the D55140 tucks into a truck cab or closet shelf. Put it on a stable flat surface and keep the hose from kinking.
No, it is designed for trim and brad nailers; a framing nailer needs higher air volume.
The 1-gallon tank fills quickly for typical trim cycles.
Check the included manual for maintenance requirements.
Fills tires fast. Good size.
This compressor is quiet and compact. It runs my nail gun without issues. The 1-gallon tank is adequate for small jobs.
I bought this to power my nail guns and inflate tires. It's surprisingly quiet for an air compressor. The 135 PSI is more than enough for my needs. It's lightweight and easy to carry around the house. The tank is small, but it refills quickly. The build quality seems solid. It's a great value.
Works fine for occasional use. The hose is a bit short. But it's a good little compressor.
I'm not a professional, but I needed a compressor for my nail gun and to inflate car tires. This one is perfect. It starts quickly and doesn't shake too much. The 1-gallon tank means it runs more often, but for home use that's fine. It's much quieter than my friend's larger model. The handle makes it easy to move. I'm very happy with it.
Keeps up with my needs.
It's quiet and compact. The pressure gauge is easy to read. I like it.
This compressor works, but it took a long time to fill a tire. Also, the tank is small, so it cycles often. Fine for very light use.
