The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other power tools and workshop machinery we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The DEWALT D55146 runs on 120V AC and carries 4.5 gallons of compressed air in a body measuring 28 inches long by 24 inches wide by 16 inches tall. At 88 pounds it is not a tool you carry by hand to each task; it belongs on a cart or in a fixed shop location. The large tank volume means less frequent motor cycling during sustained pneumatic work with framing nailers, impact wrenches, or spray guns.
At $402.99 and with 415 reviews averaging 4.5 stars, the D55146 has earned a strong reputation over an extended sales history. Owners report it handles steady production use without the overheating or pressure-drop issues that plague smaller tanks under continuous demand. The DEWALT brand also provides a recognized service network for a tool expected to see years of regular use.
The weight and physical size are real considerations. At 88 pounds this is not a job-to-job carry compressor; users planning to move it frequently will want a dedicated hand truck. The $402.99 price sits above budget twin-stack options, but the tank size, DEWALT reliability record, and 4.5-star owner rating justify the premium for regular professional or semi-professional use.
Pros
- 4.5-gallon tank reduces motor cycling under sustained pneumatic tool use
- 4.5-star rating from 415 owners reflects strong long-term owner satisfaction
- DEWALT brand provides accessible service and parts support
- 120V corded operation delivers consistent power from any standard shop outlet
- 50 units sold monthly confirms ongoing demand from active buyers
Cons
- 88-pound weight requires a cart or fixed location; not practical for frequent carry
- At $402.99 it is priced above lighter twin-stack compressors that handle finish work
- Listing does not publish CFM or PSI ratings, which are key specs for matching to pneumatic tools

Performance notes
The D55146 draws from a 120V AC line and feeds a 4.5-gallon tank in a 28 x 24 x 16 inch chassis. CFM delivery and maximum PSI are not published in the available spec data, but the 4.5-gallon capacity and sustained owner praise for high-demand use indicate it is sized for framing, roofing, or spray work rather than light finish nailing. The 88-pound body is typical of contractor-grade portable compressors in this tank size.
What buyers say
Owners frequently highlight the D55146's performance under continuous load as its key strength, noting it keeps up with framing nailers and air tools without frequent pressure drops. Common praise references DEWALT build quality and long service life. The main owner complaint is weight and the need for a cart to move it around the shop or jobsite.

Frequently asked questions
What is the CFM and maximum PSI rating for the DEWALT D55146?
CFM and PSI specs are not included in the listing data available to ToolGalaxy. Check the DEWALT product page or the compressor's data tag for those figures before matching it to specific pneumatic tools.
Can the D55146 run two nail guns at the same time?
Based on specs and verified owner reviews, the 4.5-gallon tank supports sustained high-demand use, and owners report running multiple tools. Whether two specific guns can run simultaneously depends on their combined CFM requirement versus the compressor's rated output, which should be verified from the spec sheet.
